Sammi found the “news” she was looking for in the way the Su Causeway hummed under her boots.
She wasn’t walking anywhere in particular—just along the familiar spine of stone, letting the morning crowds flow around her: porters with baskets, scholars with rolled scrolls, tourists squinting up at the stacked houses.
But her thoughts were back on the airship and at the opera.
On Xiangyun, moth-wing heart beating itself sore against the glass of Eriko’s lighthouse mind.
On Eriko in the little black dress, looking simultaneously astonished and dangerous.
On herself, and the way jealousy and protectiveness had twined together in her chest like two suspicious snakes who were trying to learn to dance.
She found Brother Wei exactly where she should have expected: striding slowly down the Causeway with his begging bowl in one hand and a folded sheet of philosophy in the other, halo ticking gently above his head.
“Good morning, half-enlightened one,” Sammi said, falling into step beside him.
“Good morning, fully-conflicted one,” he answered without missing a beat.
Sammi snorted. “That obvious?”
“You’re talking to the man whose halo has a feedback loop,” Wei said. “Your heart is loud today. What troubles it?”
She hesitated, then—because she liked how Wei never pretended that feelings were less complicated than theology—told him.
About Xiangyun’s crush and Aya’s spell. About the kabedon in the corridor. About the way Eriko had blushed, how Sammi had both wanted to wrap her in blankets and drag her back into the dress just to look at her again. About guilt: I put her in that dress, I set the beacon brighter.
Wei listened, bowl cradled in his palms like a portable shrine.
When she finished, he said, “You love Eriko. You also love stories. These two loyalties are currently rubbing together like unfiled gears.”
“Xiangyun is a story too,” Sammi admitted. “One I don’t want to crush.”
“Mm.” Wei’s halo spun once, thoughtfully. “There are vows that separate the world into what is permitted and what is forbidden. And then there are spaces made for… experiments. For truths that cannot breathe under ordinary roofs.”
He glanced up toward the green line of hills beyond the lake.
“At Lingyin Temple there is such a space,” he said. “A hidden shrine to Guanyin—Jizo to your Eriko. There, women can pledge themselves as hierodules for a day: attendants of the bodhisattva of mercy. Within that service, a little chamber is opened that sits… sideways to ordinary time.”
“Sideways,” Sammi repeated.
“Actions taken there do not erase consequences,” Wei said carefully, “but they are held gently. Karmic weight is… redistributed. Hearts may try on shapes they could not bear to wear forever.”
“And you’re suggesting,” Sammi said slowly, “that Eriko and Xiangyun—”
“I am suggesting nothing,” Wei said quickly, halo jittering. “I am merely describing an architectural feature of the spiritual landscape. What you do with topological possibilities is your department.”
But his eyes were kind.
Sammi walked on in silence for a while, the idea knocking around inside her like a loose marble.
“Could mercy look like…letting a different story happen, just once?” she asked finally.
Wei smiled. “Mercy has worn stranger costumes.”
Back at the Round Story apartment, the building let her in with a little questioning creak: Well?
Eriko stood at the round window, arms folded on the sill, chin resting on them. From here the lake was a sheet of light; the Opera House a ridiculous crown at the north end; Jin’s airship a little figure eight of shadow as it circled above the docks, testing some new whim of lift.
Sammi slipped her arms around Eriko’s waist from behind, pressing her cheek between Eriko’s shoulders.
“You look like a poem checking its rhymes,” she said.
Eriko made a soft, rueful sound. “I’ve been thinking about Xiangyun,” she admitted.
“Me too,” Sammi said. “Probably for slightly different reasons.”
Eriko turned in her arms, searching her face. “Are you angry with me?”
“For being magnetic?” Sammi snorted. “Never. For almost getting seduced in a corridor while under the influence of weaponized opera? Only mildly.”
Her expression softened.
“Mostly,” she said, “I’m thinking about…the part of you that lit up when she talked engines. How your eyes go all bright when someone meets you in that weird sky where maths and metaphysics live. I would be a terrible girlfriend if I wanted to lock that away.”
Eriko’s throat worked. “But you pulled me out of that corridor.”
“Yes,” Sammi said simply. “Because you looked cornered, not free. I will always do that.”
She hesitated, heart pounding.
“But what if there were a place,” she went on, “where you weren’t cornered? Where you could meet that side of Xiangyun with all your defenses down, and nobody got…broken.”
Eriko’s brows drew together. “You’ve been talking to Brother Wei.”
“I have,” Sammi conceded. “And he reminded me that some temples specialize in…sideways solutions.”
She told Eriko about the shrine at Lingyin as Wei had described it: a small cell behind a modest door, thick with offerings and incense, where time became soft like clay. Where women, pledging for a day as servants of Guanyin/Jizo, could ask for mercy not only for suffering but for desire itself.
Eriko listened, eyes widening, face going through several equations’ worth of expressions.
“You would…send me there?” she said at last. “With Xiangyun?”
“I would send you to yourself,” Sammi said, carefully. “To Guanyin, whose job description is literally ‘compassion,’ and to whatever configuration of you and Xiangyun feels true when no one is watching except a bodhisattva and some very nosy incense smoke.”
She cupped Eriko’s face.
“I love you,” she said. “I’m not afraid of there being more of you than I can personally occupy.”
Something hot and wet rose in Eriko’s eyes.
“You are absurd,” she whispered. “And terrifying. And I love you so much it hurts.”
“So that’s a ‘maybe’?” Sammi asked, trying for levity and almost managing it.
After a long moment, Eriko nodded. “If Xiangyun wishes it,” she said softly. “And if Guanyin is willing to host our…experiment.”
The building, listening with all its walls, shivered in sympathy. The Su Causeway sent up a faint pulse from below: Approved.
Xiangyun arrived at Lingyin Temple with her heart hammering like a mis-tuned engine.
Wei had met her at Chef Wu’s the day before, offered her tea and an offhand comment: “There is a place where unrequited love can try on a different shape for an hour. No guarantees. But if anyone deserves such a laboratory, it is a metaphysical engineer.”
He had not told her who else might be involved. He didn’t need to. The mere combination of “unrequited” and “laboratory” had sent her mind straight to Eriko, and stayed there.
Now, barefoot on the cool stones, following a novice down side corridors and around quiet courtyards, she tried to convince herself she was simply curious.
The shrine to Guanyin was smaller than she’d imagined. No towering statues; just a modest alcove with a many-armed figure half-hidden in shadow, face serene and a little amused. Offerings crowded the low table: fruit, flowers, folded petitions, tiny toy boats, single earrings separated from their partners.
A nun with a smile that saw too much greeted her.
“You come as hierodule for a day?” she asked.
Xiangyun swallowed. “If Guanyin will have me.”
“The bodhisattva has room for everyone,” the nun said. “But for this particular rite, she has chosen someone to meet you. A reflection you have been… circling.”
She led Xiangyun to a door. The wood was old; the paper panels glowed with a soft, interior light.
“Within, you are outside ordinary time,” the nun said. “What you do there will still be true, but it will not chain any of you. Serve compassion, not fear, and you’ll emerge lighter.”
Xiangyun nodded, palms slick. The nun slid the door open and stepped aside.
Inside, the little cell was surprisingly warm. Tatami mats. A low altar with another, smaller Guanyin in traveling clothes. And beside it, kneeling in simple white robes, hands folded in her lap—
Eriko.
Her hair was loose, black waterfall over her shoulders. The little black dress had been replaced by temple linen, but the effect was only to sharpen the contrast between the familiar mind and this unfamiliar setting.
For a heartbeat, Xiangyun thought: Ah. A vision. The shrine is teasing me.
Then Eriko smiled, small and shy and very real.
“Hello,” she said. “I hear today we are hired by compassion.”
Xiangyun’s knees nearly gave out.
“You—know?” she managed. “About…everything?”
“I know I’m here because Sammi loves me,” Eriko said. “And because you do too, in your own way. And because Guanyin refuses to take sides when love is trying to grow.”
She laughed softly. “Also because Brother Wei is meddlesome.”
The tension in the cell loosened; Xiangyun could breathe again.
“Are you sure?” she asked. “About being here? With me?”
“I am curious,” Eriko said honestly. “And honored. And nervous.” Her gaze met Xiangyun’s steadily. “And yes. I am sure.”
The door slid shut behind them with a final, gentle click. The air shifted—less like something closing, more like a curtain being drawn around a stage.
Outside, bells rang somewhere in the temple. Inside, time loosened its belt and sat down to watch.
What happened between them in that small, ornate room was theirs.
Later, Xiangyun would remember it not as a sequence of acts but as a sequence of recognitions: the way Eriko’s laugh felt when it happened right up against her collarbone; the way hands that usually held pens and diagrams learned the weight of shoulders and hips; how an intellectual rhythm—question, answer, counter-example—transformed into a physical one of approach and retreat and deeper approach.
Eriko, for her part, discovered that being the focus of someone’s undivided attention—mind and body—could be less like interrogation and more like worship. That her own shyness could melt into trust when held carefully enough. That desire, when given permission, had its own clear, precise logic.
There were kisses that tasted of engine oil and temple incense; laughter when knees bumped and hair tangled; long, quiet stretches where simply holding each other felt like a theorem finally balanced.
At some point, Guanyin’s little altar lamp burned low and then mysteriously brightened again, as if the bodhisattva had leaned in, smiled, and decided to give them more time.
At another, Xiangyun’s breath hitched and the world narrowed to warmth, light, and the sense of falling upward. Eriko followed—not as echo but as co-discoverer—eyes squeezed shut, hand clutching Xiangyun’s as if anchoring a proof to the page.
The rhythm of them together rose and softened, rose again, finding variations neither had completely predicted but both recognized with a kind of astonished gratitude.
Outside, on the Su Causeway miles away, the stone felt it.
Not as scandal, but as a deep, pulsing wave of release: one vector of unrequited love re-routing itself into something gentler; one careful mathematician learning yet another way to inhabit her own body; one brave engineer finally letting herself claim joy instead of only maintaining engines for others.
The bridge hummed, pleased.
When Xiangyun finally stepped back out into the corridor, the light beyond the paper panels was not noticeably different. In ordinary time, perhaps an hour had passed. In the cell, there had been enough moments to fill a small lifetime.
She felt…relaxed in ways that had nothing to do with muscles. Not cured of anything—she still loved Eriko; she probably always would—but the ache was no longer sharp. It was more like a familiar, distant mountain: part of the landscape, not a weight on her chest.
Eriko emerged after her, robe straight, hair slightly disastrous, eyes luminous. They stood facing each other, unsure for a second what shape to take now.
“Thank you,” Xiangyun said, the words too small but all she had.
“Thank you,” Eriko echoed. “For seeing me. For sharing…all that…and still being you.”
They leaned in, foreheads touching for a moment in a simple, quiet benediction that felt as holy as anything in the shrine.
Then Eriko smiled—a little shy, a little wicked. “Sammi will want to know everything emotionally and absolutely nothing anatomically,” she said.
Xiangyun laughed. “Give her my love,” she said. “And my eternal gratitude for lending you to mercy for a day.”
Eriko trotted up the stairs to the Round Story apartment with an unusual lightness in her step. The staircase, sensing the difference, creaked in a higher key.
Sammi was waiting by the round window, leg bouncing, a half-written pamphlet abandoned on the table. The moment she heard the door, she whirled.
“Well?” she blurted. “How do you feel? Did Guanyin throw lightning at anyone? Did Wei’s halo fall off? Are you okay?”
Eriko stopped just inside the room, suddenly shy. Then she crossed the space in three quick steps and wrapped Sammi in a hug so encompassing it knocked the questions right out of her.
“I feel…” Eriko searched for a word. “More spacious,” she decided. “Like someone opened a window in a room I didn’t know was stuffy.”
Sammi exhaled, relief flooding her. “And Xiangyun?”
“Still very much Xiangyun,” Eriko said, smiling. “Still an engineer. Less…compressed by longing. She sends love and reports that Guanyin has excellent structural sense.”
Sammi laughed, then sobered, eyes searching Eriko’s face.
“Do you regret it?” she asked quietly.
Eriko shook her head. “No. It was… a holy experiment. One that let parts of me speak that rarely get a microphone. And now,” she added, stepping in even closer, “I want to bring that voice home to you.”
She kissed Sammi then—unhurried, confident, with a new, subtle rhythm humming under it. Not someone else’s pattern, not Xiangyun’s exactly, but something Eriko had learned about herself in that sideways room and was now weaving into their music.
Sammi felt it: the rise and fall, the patient swell, like waves remembering a shoreline. She shivered, not with jealousy but with awe.
“Guanyin did good work,” she murmured against Eriko’s mouth.
“So did you,” Eriko replied. “For trusting me enough to let me go.”
The building vibrated happily under their feet. Down below, the Su Causeway pulsed once, like a satisfied heartbeat.
Sometimes, it thought, you held the line. Sometimes you moved the boundary stone. And every now and then, when love was brave and foolish enough, you let a new world be created in a borrowed cell and then welcomed its echoes home.
Sammi and Eriko disappeared toward the bed, laughter and low voices trailing after them, carrying that new rhythm into familiar space.
The Round Story apartment, the bridge, and perhaps even Guanyin herself listened, and were content.
Sammi always said the Yue Opera House had swallowed a minor palace and several egos and then decided it was still hungry.
Tonight, the north end of the Su Causeway blazed with its appetite. The Opera House reared out over the lake like a lacquered ship that had forgotten how to sail, its tiered balconies dripping lanterns and decorative outrage. Gilded cherubs wrestled with dragons along the cornices; stone muses held scrolls of legislation instead of lyres. From the highest box, the Thearch’s empty seat glowered politely at the stage.
Sammi adored it.
“Look at you,” she breathed, staring at Eriko instead of the building. “My sleek little theorem.”
Eriko was busy trying not to trip on the marble steps.
The lil black dress—Sammi’s prize from a tailor who owed her for pamphlet placement— hugged Eriko’s curves with scandalous precision. The neckline was modest; the fit was not. Each step made her acutely aware of her own existence.
“I am not sleek,” she muttered. “I’m…compressed.”
Sammi’s grin went incandescent. “Compressed elegance. Very efficient.”
Inside, chandeliers the size of minor planets glittered. The foyer churned with silk, brocade, gears and gossip: court ladies with cleverly hidden spyglasses, foreign merchants with translation charms, theater kids in elaborate makeup fetching drinks for divas.
Near the grand entrance, Brother Wei stood beside a marble column, begging alms and witticisms with equal sincerity.
His gear-halo ticked faintly, now almost—but not quite— symmetrical.
“Spare a proverb for the partially enlightened?” he called to passersby. “Accepting spare change, sharp rebukes, and constructive paradoxes.”
Eriko slowed. “Brother Wei.”
“Ah!” Wei brightened. “Patron saint of argumentative staircases.”
Sammi laughed. “No, that’s mostly Eriko.”
Eriko reached into the small embroidered purse that did not go with the dress but did go with her anxieties. She drew out an old coin—worn, dark, heavy with the touch of countless thumbs.
“This should be in a museum,” Wei said quietly, taking it.
“Tonight,” Eriko whispered, “it belongs in your journey. Complete it, brother.”
Something in the weight of the coin clicked against the teeth of his halo. One tiny cog shifted. The sound was almost lost beneath the lobby chatter.
Wei looked at her, eyes suddenly bright and damp. “I will…try,” he said. “Enjoy the opera. Beware the final syllables.”
The curtain rose on the first act to reveal a set that looked suspiciously like the Su Causeway rendered by someone who’d only ever heard rumors about it.
“This feels targeted,” Sammi murmured.
“It is a satirical opera about municipal infrastructure,” Eriko pointed out.
Onstage, actors in exaggerated court robes argued over bridge budgets while dancers dressed as stones, beams, and bureaucratic seals whirled behind them. Old Handle’s lyrics skewered everyone with equal glee: corrupt officials; forgetful architects; citizens who complained about taxes but insisted on living above tea houses in flood zones.
Up in the highest tier, Aya of the Yue reigned.
She entered in a burst of crimson silk, her sleeves like the wings of furious birds, her gaze a precision instrument. When she sang, the air tightened. Her voice could slip from traditional Yue ornamentation into something almost modern, then back, without dropping a bead.
At the climax of the act, she delivered a final line about “bridges that bear more than they admit” with such precision that the chandeliers chimed in sympathy.
Somewhere, unnoticed, three wine glasses cracked. A minor courtier burst into tears and had no idea why.
In the lobby during first intermission, Sammi vibrated like a tuning fork, half from Aya’s artistry, half from narrative overload.
“She weaponized the rhyme,” Sammi babbled to a circle of Thearch’s concubines and visitors from Seleucia-on-Tigris. “Did you hear how she slipped the scansion just off enough to imply the bridge was complicit?”
“Oh yes,” sighed a concubine in peacock blue. “We shall be referencing it for months. I may have it embroidered on a scandal.”
“Old Handle has outdone himself,” said a Seleucian scholar, adjusting his spectacles. “Though I suspect he is going to be exiled to a garden again.”
Sammi soaked up gossip like a sponge dropped in tea. She didn’t notice, at first, the ripple that went through the floor, up her spine, into the back of her skull.
It was not sound. It was pattern.
The Su Causeway, whose foundations underpinned the Opera House’s flamboyant footings, had been listening. It did not entirely approve of the building’s pretensions, but it enjoyed Aya’s voice and Old Handle’s commentary. More importantly, it had felt the particular resonance of that last syllable.
Aya had pronounced it in the key of Reckless Confession.
The tone ran along nerves of stone and steel, through the Causeway’s length, out into the city. Sensitive hearts caught it like a virus—with varying symptoms.
Cap’n Jin, miles away at dock, suddenly had the urge to tell his airship that he truly appreciated it. Chef Wu almost admitted the secret of his spice blend to a customer before biting his tongue.
And deep in the Opera House, in a corridor near the boxes, Engineer Xiangyun froze mid-step.
Xiangyun had come in her work clothes, because what else was there? Her idea of dressing up was changing into the less-burned tunic and braiding her hair more symmetrically. She felt as out of place in the velvet corridors as an honest invoice in a court archive.
But the opera…that she understood.
Aya’s voice obeyed the same rules as engines: pressure, release, resonance. Old Handle’s libretti were full of hidden mechanisms. Xiangyun sat in the cheap seats and mapped each motif to a gear, each key change to a pressure valve.
When Aya’s last note hit, it went straight through Xiangyun’s calculations and struck that tender, well-defended place in her chest labeled Eriko.
Suddenly the idea of not saying something felt mechanically unsound.
“My system is under-vented,” she realized, a little dizzy. “This is a safety issue.”
She downed a shot of yè from a passing tray—plum, rice, bad decisions—and stumbled out during intermission in search of fresh air, or failing that, one specific mathematician in a little black dress.
Eriko had fled the crowd the moment the lights went up.
Aya’s final note had left her oddly raw, as if the song had peeled back a layer of abstraction. The dress didn’t help; every glance she caught in mirrored panels made her feel like a misprinted diagram.
She slipped into a side corridor where the traffic was thin, leaning back against the cool marble.
I am foolish, she thought. I look like I am trying to be someone else.
She was still arguing with herself when Xiangyun found her.
“Eriko.”
Her name in Xiangyun’s mouth came out roughened by yè, soft at the edges, too honest.
Eriko straightened. “Engineer Xiangyun. Are you—”
“Don’t move,” Xiangyun blurted, and for a heartbeat Eriko actually obeyed because the command sounded less like an order and more like a plea to a misaligned gear.
Xiangyun stepped in, close—so close Eriko smelled metal, engine oil, and plum wine. She planted her right palm on the wall just beside Eriko’s head, leaning in for balance.
It was, unmistakably, the classic anime kabedon pose.
Eriko’s brain provided this information helpfully and then vacated the premises.
“Listen,” Xiangyun said, staring not quite at her but at some point just beyond her shoulder, as if reading equations from the air. “I know you’re taken. By Sammi. Obviously. Engines run better in paired systems, I get it. I respect it. But Aya’s stupid note hit my stupid heart and now I have…unvented declarations.”
Eriko’s blush threatened to achieve escape velocity.
“Unvented—”
“Feelings,” Xiangyun said, wincing at her own word choice. “Pataphysical pressure. Trollish crush on your brain. And the rest of you. I am attempting a controlled release before something explodes.”
She slapped her free hand against her chest. The engines back at dock, miles away, coughed in sympathy.
“I am not—” Eriko swallowed. Her thoughts skittered. Aya’s note still hummed under her skin, making everything feel possible, which was not helpful. “I am not good at…receiving declarations.”
“I’ve noticed,” Xiangyun said, a twisted little smile flickering. “You sidestep compliments like falling tiles. But you deserve to know that someone else sees you as…well, as gorgeous mathematics in that dress, frankly.”
The compliment landed like Aya’s note, and Eriko’s knees nearly gave out.
Somewhere beneath them, the Su Causeway felt the way the pressure in the hall was spiking and thought, No, no, this is going to shear a beam.
It reached for its newest trick: psytrance linkage.
In the lobby, Sammi was mid-story, explaining to a Seleucian merchant the finer points of protest pamphlet typography, when her feet suddenly buzzed.
It was not an actual vibration. More like the floor whispering, very insistently: HEY. HEY. YOUR PERSON. CORRIDOR C. LEFT TURN PAST THE GOLDEN CHERUB THAT LOOKS LIKE IT REGRETS EVERYTHING.
Sammi’s focus snapped into crystalline clarity. The chatter around her dimmed, colors sharpening.
“Excuse me,” she said politely to the circle of concubines. “My structural integrity is needed elsewhere.”
One of them arched a knowing brow. “Domestic emergency?”
“Romantic engineering problem,” Sammi replied, already moving.
The Causeway guided her like a beat in her own pulse. Down the side hall, past a pair of bickering critics, around a cluster of musicians tuning weirdly sentient instruments, to Corridor C.
She turned the corner and saw:
Eriko, pressed mildly but unmistakably against the marble, eyes wide and dark. Xiangyun leaning in, one arm braced above her, the other fisted at her side, shoulders tense. Two faces close; too close. Aya’s lingering spell glittering between them like stray notes.
Sammi’s heart thudded once, very loud.
Then she moved.
“Eriko,” she called, letting every ounce of affection she had pour into the name.
Eriko’s head snapped toward her, relief flooding her face like light through paper. The spell wobbled.
Sammi didn’t yank or shout. She slipped between them like a practiced stagehand sliding into a scene change, one hand on Eriko’s waist, the other gently but firmly nudging Xiangyun’s shoulder back.
“Whoa there, engineer,” she said, keeping it light. “Careful with the metaphysical pressure. These walls are load-bearing.”
Xiangyun froze, horror dawning through the haze of yè.
“I—Sammi—I wasn’t—well, I was, but—oh no.”
She jerked her hand away from the wall as if it had burned her. Then looked at Eriko, at Sammi’s arm around Eriko, and went dead pale beneath the smudges of engine soot.
“I’m so sorry,” she blurted. “That was… Aya’s fault. And mine. And the plum wine. And Old Handle’s structural metaphors. And possibly the moon. But mostly mine.”
Eriko exhaled shakily. “No harm,” she managed. “Just…surprise.”
Sammi felt the tremor in her—nerves, yes, but also that stylishly aroused flush, that unsettled thrill. She tucked Eriko closer, a clear answer.
“Look,” Sammi said, catching Xiangyun’s eye. She softened her voice. “You’re allowed to have feelings. You’re even allowed to say them out loud. You’re not allowed to corner my girlfriend while under magical vocal influence. That’s a safety violation.”
Xiangyun winced. “I’ve violated my own protocols.”
“Next time you get hit with an Aya Note of Reckless Confession,” Sammi went on, “come find me first. I’m structurally designed for overflow melodrama.”
That won a tiny, crooked laugh out of Xiangyun. “You…would let me rant at you?”
“Sure,” Sammi said. “I collect stories. ‘Pataphysical engineer with unrequited crush’ is excellent material.”
Eriko elbowed her gently. Sammi grinned. “I mean that respectfully,” she added. “And I promise to remind you—kindly—that I go home with Eriko.”
Xiangyun scrubbed her hands over her face. “Understood. Absolutely. No more anime poses. The engines will be mortified when they find out.”
“In fairness,” Eriko said, surprising both of them, “it was… structurally impressive.”
They stared at her.
“I mean,” she floundered, “the torque distribution? You didn’t lean on me at all, just the wall. Very considerate load allocation.”
Xiangyun blinked, then laughed—a real laugh this time, giddy with relief and lingering humiliation.
“You are ridiculous,” she said fondly. “And perfect. And I will accept my fate as a supporting character.”
Sammi squeezed Eriko’s hand. “Best supporting engineer,” she amended. “We’ll put it on the playbill.”
From somewhere high above, Aya’s diva instincts pinged: someone is improvising character development without me. She made a mental note to steal this corridor scene for a future opera.
They went back to the lobby together, not quite as a trio—the spacing had changed—but with less static in the air.
Brother Wei, still working the concourse, saw them approach and tilted his head, listening to the faint changes in their heartbeats.
“Ah,” he said. “A nearly-misplaced confession, a timely intervention, three hearts learning about boundary conditions.”
Sammi arched a brow. “You get all that from our footsteps?”
“From your halos,” Wei said, touching his own. “Yours are just invisible.”
He reached into his sleeve and produced a small, folded scrap of paper, pressing it into Xiangyun’s oil-stained hand.
“For when the engines are loud and the illusions louder,” he said.
She unfolded it later, backstage, to find a single line:
Unrequited love is still love; it just travels a one-way bridge. Remember to watch the scenery.
On the other side, in tiny writing:
P.S. There are other bridges.
Her throat tightened—but this time the pressure felt almost…bearable.
When the bell rang and the audience trickled back in, the Su Causeway shifted its attention again. Aya had another act to sing, and this time it had a favor to ask.
In the wings, Aya felt the bridge’s nudge as a prickle along her spine. Old Handle, scribbling last-minute changes on his score, glanced up.
“Hmm?” he muttered.
“The Causeway wants a different cadence,” Aya said.
“Of course it does,” Handle sighed. “The bridge is a worse critic than you are.”
But he adjusted the line.
Near the end of the second act, Aya stood alone at center stage, the orchestra quiet beneath her. She sang of misaligned towers, of roads that almost met, of hearts that had to learn to run on parallel tracks without collision.
On the final syllable, she chose not Reckless Confession, not Shattering Grief, but a rarer mode: Gracious Reconfiguration.
The note flowed out over the velvet seats, climbed the boxes, seeped through plaster and stone. It washed over Sammi, Eriko, Xiangyun, Brother Wei, even Old Handle in his garret, listening through a cracked window as he revised next week’s satire.
It didn’t erase Xiangyun’s feelings; it didn’t mute Eriko’s fluster or Sammi’s possessiveness. It merely…rearranged their vectors, so they lay alongside each other instead of at dangerous angles.
In the dark, Sammi laced her fingers with Eriko’s. Eriko laced back, less self-conscious now, dress and all.
Xiangyun, in the cheap seats, let herself imagine—just once—that she was the heroine in an opera of impossible love. Then she smiled, shook her head, and started designing in her mind a new valve for Aya’s spell-notes: something to divert excess courage into productive channels, like better engine tuning.
Brother Wei felt his halo shift minutely again. Not a full click this time, but a smoothing of motion. Enlightenment, he reflected, might simply be the art of letting other people’s stories pass through you without derailing your own.
When the opera ended in a blaze of applause and satirical fireworks, the crowd poured out onto the terraces overlooking the lake.
The Su Causeway carried them all: concubines and foreigners, critics and monks, the odd dizzy engineer, one exhausted diva, one over-caffeinated librettist.
Sammi and Eriko slipped away to their favorite vantage point, where the Opera House’s reflection shivered in the water like an over-decorated ghost.
“That was…” Eriko began.
“Too many metaphors per minute?” Sammi suggested.
“Exactly enough,” Eriko admitted. She glanced down at herself, then sideways at Sammi. “Did I…look ridiculous?”
“You looked like the theorem that proves happiness is possible,” Sammi said without hesitation. “Also your butt was amazing.”
Eriko made a strangled noise and hid her face in Sammi’s shoulder.
Across the bridge, Xiangyun leaned on a lamppost, feeling the engines’ murmur through the stone.
She watched them for a moment—Sammi’s easy affection, Eriko’s flustered joy—and let her own chest ache in a way that felt oddly…clean.
“Okay,” she told the Causeway under her breath. “Lesson received.”
The bridge thrummed, pleased.
It had shepherded another small crisis into a slightly better shape. Aya had sung the right note; Sammi had arrived in time; Xiangyun had stepped back without vanishing.
Old Handle, somewhere above them, was already rewriting the whole thing into a scene for his next opera: “The Engineer, the Philosopher, and the Bridge That Knew Too Much.”
The night settled around Song Hangzhou like a silk curtain. Lanterns bobbed. The lake held the city’s reflections gently, even the ridiculous bits.
And the Su Causeway, mercurial and proud, stretched itself under the weight of all these intertwined stories, humming with satisfaction.
Tomorrow, there would be letters to deliver, stew to serve, airships to launch, operas to write. But for now, it was enough that everyone had made it through the intermission with their hearts—if not unshaken—at least more truthfully aligned.
Cap’n Jin’s airship was never quite entirely docked.
Even when its mooring lines were looped around the iron rings sunk into the Su Causeway, the little craft trembled faintly, as if remembering clouds.
From most angles it looked like a river junk that had somehow grown a dirigible for a soul. A narrow wooden hull hung under a gas envelope stitched from patched silk and lacquered paper, its surface fluttering with inked sutras and fragments of weather reports. Thin brass ribs curved along the belly like a cage someone had half-finished and then forgotten to close.
From the underside of the hull, a cluster of engines protruded: pipes, gears, vents, and the occasional prayer-flag. They exhaled a steady, contented hum that sounded suspiciously like someone snoring.
That someone was Xiangyun.
Xiangyun was the metaphysical engineer, the other half of the crew and, according to rumor, the one who had convinced the airship to exist in the first place.
She was small, sharp-shouldered, with hair that perpetually smelled of warm metal and rain on stone. Her work clothes were a patchwork of burn holes and ink stains. She slept in a hammock slung between two engine casings; she woke to the tick of gauges and the subsonic murmur of pataphysical equations.
“The engines like to dream,” she explained to anyone who asked. “If I’m not there to listen, they get anxious and the propellers forget which way is forward.”
She said this in the tone of someone discussing perfectly ordinary mechanics, which technically it was—not her fault if reality insisted on being literary.
Their usual route ran from Hangzhou out into the mountains, where the major maths, convents, and hermitages of the Song realm had taken a collective vow of partial internet access.
“We will know all things,” the abbots had proclaimed, “but not about each other’s relationships.”
Under this vow, monasteries were allowed:
Cloud backups of sutra commentaries
Access to mathematical journals and preprint servers
Security patches for the temple routers
They were not allowed:
Personal correspondence
Love letters
Cat pictures
The result, as Cap’n Jin often said, was that the monks knew the latest developments in abstruse topology but had no idea their cousins had had children.
“That’s why I fly,” he’d tell anyone who would listen. “Somebody has to bring them handbills, postcards, and angry letters from aunties. The Dharma may be for all beings, but so is gossip.”
He did it at his own expense, too. The monasteries fed him, the hermits brewed questionable herbal tonics in gratitude, but money? Rarely.
“The universe will repay me in scenic views,” he said cheerfully.
On a bright, breezy morning, while Chef Wu was ladling out breakfast congee to commuters and the Causeway was settling into its daily rhythm, two familiar figures appeared at the airship’s dock.
Sammi arrived first, hair in a scarf the color of riotous sunrise, satchel clanking with notebooks and spare type blocks. She hopped up onto the gangplank as if boarding ships was just walking in a slightly more interesting direction.
Behind her, Eriko climbed more slowly, one hand on the rail, the other clutching a rolled-up sheaf of diagrams. The breeze made geometry of her sleeves.
Cap’n Jin, who had been checking a mooring knot that technically didn’t exist in Euclidean space, straightened.
“Well if it isn’t my favorite balcony-dwellers,” he called. His dark braid snapped in the wind like a flag. “Come to admire my majestic craft?”
“We’ve come to beg passage,” Sammi said. “I’ll admire as a free bonus.”
Eriko nodded, trying to look dignified despite the flush in her cheeks. “I have a number of…theoretical questions about pataphysical lift in small airships.”
“And I,” Sammi added, “have a number of practical questions about mountainous villages and the stories they are hiding from me.”
Cap’n Jin’s eyes sparkled. “A scholar and a storyteller. The engines will be thrilled. Come aboard.”
As they crossed onto the deck, a hatch banged open and Xiangyun popped up like a startled cat.
“Who is putting non-standard weight on my carefully calibrated planks?” she demanded, wiping oil from her hands with a rag that might once have been white.
Then she saw Eriko.
The engines, which were linked sympathetically to her mood, dropped half a note in their hum. The whole airship seemed to inhale.
“Ah,” Xiangyun said, eloquently.
They had met before, of course—brief conversations at Chef Wu’s counter, snatches of talk about configuration spaces and guilty staircases. Eriko’s mind shone for Xiangyun like a lighthouse; the clear, precise way she spoke about impossible things made Xiangyun want to diagram her sentences and then frame the diagrams.
Now, seeing her on the deck, xiangyun’s heart did something complicated and non-Newtonian.
Eriko smiled politely. “Good morning, Engineer Xiangyun. It’s kind of you to permit us aboard.”
“Not kind,” Xiangyun said, then remembered to tack on, “I mean, it is kind, but it is also scientifically necessary. I’ve needed another observer for my engine notes.”
Sammi, who had the social perception of a gossip column in human form, clocked the way Xiangyun’s gaze hovered around Eriko like a satellite.
She stepped casually closer to Eriko, looping their arms together.
“As long as the scientific necessity includes both of us,” Sammi said, sweet as steamed buns but with a definite underflavor of mine.
Xiangyun’s eyes flicked to their joined arms, then away. Her jaw tightened, just for a heartbeat, before smoothing into a rueful smile.
“Of course,” she said. “The engines already know you come as a set.”
Behind them, the hull gave a faint creak of agreement.
Before every departure, Xiangyun performed a pre-flight check that looked, to the untrained eye, like a cross between a maintenance routine and a ritual.
She tapped each gauge three times, listening for the tiny answers. She checked the tension of the propeller chains, the alignment of the brass fins, the angle of the remains of last week’s rainbow still caught in the rigging.
“Is all this strictly necessary?” Sammi asked, watching her trace a pattern of concentric circles on the main engine casing with a stick of red chalk.
“Only if we want to arrive where we mean to,” Xiangyun said. “Airships don’t just move through space. They move through about-ness.”
Eriko’s eyes lit. “Intentional vectors?”
“Exactly.” Xiangyun turned to her, suddenly animated. “If your primary purpose is trade, you get one kind of path—stable, well-marked, full of other merchants. If your primary purpose is pilgrimage, different currents, more unpredictable weather, higher likelihood of birds with opinions. Our purpose—”
“—is delivery of letters and unasked-for enlightenment,” Cap’n Jin cut in. “So we get the scenic routes.”
“The pataphysical structure of a small airship,” Xiangyun continued as if he hadn’t spoken, “relies on being more narratively interesting than the ground. That’s what pulls us up.”
Eriko looked like someone had handed her a new axiom set for the universe.
“So lift is proportional,” she said slowly, “to story density per cubic meter.”
“Among other factors,” Xiangyun agreed. “Weight, temperature, number of unresolved romantic tensions on board—”
Sammi coughed.
Xiangyun winced, then added briskly, “—and the quality of the captain’s hat.”
Cap’n Jin touched his battered cap protectively. “This hat has seventeen successful landings in it.”
“And three very impressive crashes,” Xiangyun pointed out. “Which is why the engines respect it.”
Sammi grinned. Eriko flipped open her notebook and began scribbling equations with suspicious speed.
The Causeway, listening under their feet as ropes were cast off, decided it approved. A small airship leaving from its railings made the whole day feel more expansive.
When the propellers spun up, the ship rose with the air of a sigh fulfilled. The Causeway let them go, relishing the tug, then settled back as the hull cleared the last lanterns.
Hangzhou slid away beneath them: steampunk houses leaning over canals, the glint of Chef Wu’s tiger-oven, the long curve of the Su Causeway itself, stripes of shadow and stone.
The lake shone like a polished mirror, reflecting a second ship that flew upside down beneath it, keel kissing clouds. The reflection-ship winked at them and then dissolved into ripples.
Sammi pressed her face to the rail, laughing.
“You see that?” she called.
“Of course,” Xiangyun said. “Our airship has a counterpart in the water’s imagination. Very good luck. Unless you fly low.”
They rose over the city walls, over terraced fields, into the embrace of the mountains.
At each hermitage, Cap’n Jin brought them down with the swaggering grace of a man who trusted both his ship and dumb luck. Monks in practical robes trudged out to meet them, hands ink-stained from digital sutras printed on rice paper. They traded parcels: bundles of scrolls going out, sacks of tea and carefully wrapped jars of pickles coming in.
At one convent, a stern abbess inquired whether Cap’n Jin had, once again, smuggled any “unsuitable magazines” inside the bundles of algebraic geometry.
“Perish the thought,” Jin said, finishing a wink he never quite started.
The abbess opened the bundle and shook out three hand-printed zines with titles like “The Metaphysics of Staircases (Illustrated)”.
Sammi beamed from the deck. The abbess sighed but tucked them under her arm.
At a mathematicians’ retreat carved directly into the rock, Eriko disappeared for nearly an hour into a heated discussion about topologically interesting noodles. Xiangyun hovered at the edge of the group, listening more to Eriko’s questions than the answers.
When Eriko finally emerged, cheeks flushed, she found Xiangyun leaning against the railing, pretending to adjust a valve that didn’t need adjusting.
“How do you keep them from falling off?” Eriko asked, nodding toward the engines. “The equations, I mean. They’re all so… delicate.”
Xiangyun shrugged. “I don’t. I fall with them. I just make sure the ship falls in the same direction.”
“That sounds terrifying,” Eriko said—and then, softly, “and familiar.”
Their eyes met; something unspoken jumped between them, a spark that searched for tinder.
At that precise moment, Sammi appeared, shuffling a stack of hastily scribbled interviews.
“You two ready?” she chirped. “The hermits have run out of tea to offer and have started boiling their socks.”
Xiangyun stepped back. “Ready,” she said, voice only slightly tight.
Eriko reached for Sammi’s hand as they climbed back aboard. It was instinctive, casual, utterly clear.
Xiangyun watched their joined fingers. Then she squared her shoulders, patted the nearest engine casing, and whispered, “All right. We fly on unrequited parameters. We’ve done worse.”
The engine hummed in sympathetic, slightly melancholy agreement.
By late afternoon, mist had gathered in the valleys like thoughts that didn’t want to settle. Their final stop was an old monastery perched on a ridge, its roofs layered like stacked questions.
As they descended, bells rang—a slow, off-kilter pattern, like someone had dropped a standard chime sequence and put it back together wrong.
“That’s Brother Wei’s doing,” Cap’n Jin said. “He’s been here re-calibrating their alert system. Or mis-calibrating. Hard to say.”
They touched down on a flagged terrace. A small group of monks approached, led by Brother Wei himself, gear-halo gently spinning above his shaved head.
The halo was a delicate mechanism of interlocking brass cogs, suspended just beyond his skin. Today it ticked with a faint, uneven rhythm, as if one tooth somewhere was not quite catching.
“Ah, my accidental taxi,” Brother Wei greeted them. “I am in need of transportation.”
“To where?” Jin asked.
Wei smiled faintly. “To wherever the Su Causeway is.”
“That,” Jin said, “we can do.”
As the monks loaded a single modest bag onto the ship, Eriko studied Wei’s halo with the fascination of one engineer looking at another’s half-finished project.
“I thought you were undergoing retreat,” she said. “To correct your… percentages.”
“Indeed,” Wei sighed, climbing aboard. “It turns out you cannot integrate enlightenment by parts. The error term remains.”
“Can I write that down?” Sammi whispered, already doing so.
Wei sank onto a coil of rope, the halo whirring as if settling into a favorite groove. “They say the Causeway has acquired…opinions,” he said. “And that it remembers the old days when mountains were more metaphorical. I thought perhaps a change of supporting infrastructure might shake something loose.” He glanced up. “At the very least, I can get decent stew from Wu again.”
Xiangyun, who had a soft spot for all beings who lived partially embedded in machinery, patted his shoulder.
“The Su Causeway specializes in emotional load-bearing,” she said. “It’s a good place to rest your gears.”
The airship turned toward home.
By the time they reached Hangzhou, the sun was sliding behind the western hills, turning the lake into molten copper.
The Su Causeway rose ahead, stone spine glowing. From this height, it looked like a single, thoughtful brushstroke drawn across the water.
As the airship descended toward its moorings, the bridge felt the familiar tug of their approach. The stress currents in its stones adjusted. It tasted the incoming load: engines still buzzing with distant mountains, letters in satchels, one half-baked enlightenment with mechanical garnish.
Ah, thought the Causeway. The monk with the lopsided halo.
It remembered Brother Wei’s earlier visits—his meditative pacing, the way his thoughts had thrummed against its surface like a drum slightly out of tune. The Great Shaking had rearranged many things; perhaps it could shuffle his insights as well.
The ship bumped gently against the mooring posts. Ropes flew; hands caught.
Brother Wei stepped down onto the stone and stopped.
His halo ticked louder, sudden.
Beneath his feet, the Causeway experimented with a very small tremor—nothing anyone else would register, just the architectural equivalent of a throat-clearing. A ripple rolled along the stones, up through the soles of his sandals, into his spine.
“Mm,” he said.
The halo spun, hesitated, then clicked forward one notch it had never reached before.
Gear teeth met where they had always failed to meet. A tiny curl of displaced ignorance evaporated with a soft pop, like a soap bubble being punctured by a well-aimed koan.
Sammi, stepping down behind him, saw the gear ring adjust.
“Did your hat just fix itself?” she blurted.
“Enlightenment is not a hat,” Wei said automatically. Then he lifted a hand, touched the halo, and frowned in wonder. “But…something shifted.”
The Causeway, emboldened, tried another trick. It remembered the keen little quake from the day of the Thearch’s crossing and reproduced a gentler version: a barely audible thrum corresponding to the resonance of two people finally finding each other.
This time, the vibration carried not only through Brother Wei’s bones but through the brass of his halo. Several smaller cogs wobbled, then settled into new alignments.
Visually, the change was subtle; structurally, it was a minor revolution.
Brother Wei blinked.
For a moment, every sound on the Causeway—the merchants shouting, the distant hiss of steam, the plop of oars—fell into a pattern he could almost see. A web of interactions: stew leading to conversation, conversation to courage, courage to small earthquakes, earthquakes to slightly improved governance.
“Oh,” he said softly. “I see. Not all the way. But further.”
“How much further?” Eriko asked, eyes sharp with curiosity and concern.
Brother Wei considered, listening to the tiny ticks above his head.
“I would say,” he replied, “I am now approximately three-quarters enlightened, with a margin of error of… five percent.”
“That’s a notable improvement,” Xiangyun said.
“Is the remainder important?” Sammi asked.
“Very,” Wei said. “It is the part that keeps me from being insufferable.”
The Causeway preened a little, in a granite kind of way.
Chef Wu, hearing the ship had returned, sent over a tray of stew and tea as a landing tax. The four of them—Sammi, Eriko, Xiangyun, Brother Wei—gathered near the moorings to eat, bowls cupped in hands gone cold from altitude.
“So,” Sammi said between spoonfuls, “how does it feel, Brother Wei? Any new revelations about the nature of reality? Subtle insights? Sudden desire to reorganize all the temple shoe racks?”
Wei flexed his toes thoughtfully. “Reality still appears annoyingly persistent,” he said. “But it feels… kinder. The errors seem less like failures and more like… annotations.”
Eriko’s gaze drifted along the length of the Causeway, up to their own crooked building with its round window-eye, now glowing softly in the dusk.
“The Su Causeway is good with annotations,” she said.
“It is,” Wei agreed. He turned his head, halo spinning with deliberate slowness. “And you two? Any shifts in your own…percentage?”
Sammi’s grin turned mischievous. “Oh, we are fully, gloriously, statistically-inappropriately in love.”
Eriko elbowed her, but didn’t deny it.
Xiangyun, watching, felt the familiar pinch in her chest. It hurt in that clean way that said: this feeling is real, even if it never lands where you wish. She took a deep breath, letting engine-smoke and stew-steam fill her lungs.
The engines, sensing her mood, shifted into a low, reassuring purr.
“You know,” she said slowly, “unrequited isn’t the same as unproductive. Pataphysically, I mean. An asymmetrical vector still moves the ship. Sometimes more efficiently.”
Eriko turned to her, expression serious. “You deserve symmetry too, though,” she said.
Xiangyun met her eyes, then laughed softly. “One miracle at a time. Today I got to show you how lift works. That’s already better than last week.”
Cap’n Jin, who had been quietly eavesdropping from the edge of the group, raised his tea cup toward the bridge.
“To small ships, overloaded stories, and load-bearing friendships,” he toasted.
The Causeway accepted the dedication, feeling the pressure of their feet as both literal and metaphorical. It carried their weight, their bowls, their half-fixed enlightenments, and their hearts with equal competence.
That night, long after the last tram had rattled to its depot, the Su Causeway lay awake.
It replayed the day’s vibrations: the airship’s departure, the letters exchanged in mountain winds, Brother Wei’s halo click, Xiangyun’s quiet courage, Sammi and Eriko’s laughter spilling onto its stones.
Once, it had existed only to connect shore to shore, garden to garden, palace to poets. Now it found itself doing…more.
I am not merely a road, it realized, somewhat startled. I am also a…correction mechanism.
Not for morality or law—those flowed over it like rain. No, its gift seemed to be subtler: nudging souls and structures a few millimeters closer to where they fit, whether that was a rebellious apartment building, a slightly crooked monk, or a tiny airship that refused to obey normal physics.
Very well, the Causeway decided. If the mountains have their hermitages and the palaces their courts, I shall be the place where things align by accident.
Far above, Jin’s airship swayed gently at its moorings, half in this world, half in footnotes. Xiangyun slept with her hand on a warm engine pipe. Brother Wei dreamed of staircases that led simultaneously up, down, and inward. Sammi and Eriko, in their round-window apartment, lay tangled and content, the building humming approval under their bed.
The Su Causeway held them all, stone and story intertwined, quietly pleased with its new hobby.
Tomorrow, it thought, it would see what else needed a small, strategic shake.
