The Burgundy Coefficient: Rong Xi and her Penchant Habit of Looning

Chapter One

The Library, and a Question That Did Not Belong There

Caleb had chosen the third-floor west stacks of Meridian College’s library for the same reason he always did: nobody came here during lunch except people who wanted to disappear. The windows faced the quad’s maple trees. The radiators clicked like old clocks. The air smelled of dust, toner, and the faint citrus of whatever the janitors used on the tables.

He sat with his back to the poetry section, phone tilted low, stylus moving in short, nervous strokes.

On the screen, a girl in a sailor collar was mid-leap across a rain-slick rooftop. He had been trying, for forty minutes, to get the weight of her landing right. Manhua wanted motion. Webtoons wanted clarity. His hand wanted both and delivered neither. The sandwich in his bag had gone warm and sad.

He redrew the knee.

Then a shadow fell across the screen.

“Wanna chat?”

The voice was bright, a little accented, and completely uninterested in the sacred quiet of the west stacks. Caleb looked up so fast his stylus squeaked.

She was standing with both hands behind her back, leaning forward just enough that her long dark hair slid off one shoulder. Straight bangs. Amber-brown eyes that seemed slightly too large for the rest of her face, as if someone had drawn her first as a close-up and then remembered she needed a body. The body, when his gaze unwisely dropped and then scrambled back up, was soft and generous: white button-down stretched across a full chest, navy pleated skirt sitting on wide hips, thick thighs, white crew socks, brown loafers. She smiled like she had practiced smiling in a mirror and decided the biggest version was the correct one.

Sophomore. Transfer. He had seen her once in the science building hallway, carrying a crate of something that squeaked.

“I—” Caleb said, which was not an answer.

She pointed at his phone with her chin. “That landing is wrong. Her center of gravity is too high. If she is heavy in the chest and hips, the down-force should sit lower. Also the hair. Hair does not freeze like that in wind.”

He stared at her.

“I am Rong Xi,” she added, as if that explained the critique. “You are the boy who draws in here every Tuesday and Thursday. I have been meaning to say something. Today I said it.”

“Caleb.”

“Caleb.” She tasted the name, nodded once, and sat down across from him without waiting to be invited. The chair complained. She did not. “Your lines are good. Your physics are timid. That is okay. Physics can be taught.”

“I wasn’t—” He locked his phone, then felt stupid for hiding it. “I was just doodling.”

“Doodling is how serious things start.” Rong Xi folded her arms on the table. The shirt pulled. A small silver pin on her collar caught the light: a circle, simple, like a balloon seen from above. “Do you like balloons?”

The question arrived with no runway.

Caleb blinked. “Balloons.”

“Yes.”

“Like… party balloons.”

“Like the ones you make,” she said, and then, seeing his face, laughed under her breath. “Okay. Not you. Me. I make them. From scratch. Latex compounding, pigment dispersion, neck reinforcement, burst-pressure testing. The science club is technically a materials club, but everyone calls it the balloon club because I am the president and I am not subtle.”

A librarian far away stamped something. A printer woke and died.

“That’s…” Caleb searched for a word that was not weird and landed on, “specific.”

“Thank you.” She said it as praise. “Most people say childish. Balloons are not childish. Balloons are a thin skin holding a disagreement with the atmosphere. Very romantic, if you think about it correctly.”

He did not know how to think about it correctly. He knew that her smile had a little gap of light at the corner, and that she talked with her whole face, and that his sandwich was still uneaten.

“Why me?” he asked.

Rong Xi tipped her head. “Because you draw girls who look like they might fall, and then you try to catch them with better anatomy. Also because you sit alone and do not look annoyed when people exist near you. That is rare. And because—” She reached into the tote bag slung over the chair and pulled out a crumpled square of burgundy rubber, no larger than a washcloth, matte and wrinkled, smelling faintly of something warm and chemical. “—I finished a new batch this morning and I wanted to show someone who would not immediately ask if I was okay.”

Caleb looked at the deflated thing. It looked like a piece of wet cloth that had decided to be ambitious.

“You made that.”

“I made that.” Pride, unhidden. “Want to see it become a sphere?”

“Here?”

She glanced around the stacks as if considering committing a crime in the poetry section, then shook her head. “Library air is too dry. Also Ms. Pell would kill me. Lab Three. After your next class. You have Drawing II at two, yes? I checked the studio list.”

“You checked—”

“Wanna chat is a door,” Rong Xi said, standing, already stuffing the burgundy square back into the tote. “Lab Three is the room behind the door. If you do not come, I will assume your landing stays wrong and I will be a little sad, but I will survive. If you do come—” The smile again, huge and slightly dangerous. “—bring your phone. I want you to draw the inflation. Nobody draws inflation correctly. They always make it look like a balloon is just getting bigger. It is not. It is choosing a shape.”

She left the way she had arrived: as if the library were a hallway she happened to be using.

Caleb sat very still for a long time. Then he unlocked his phone. The rooftop girl still hung in the air, knee wrong, hair frozen.

He lowered the center of gravity.

Chapter Two

Transfer Students and Other Unstable Compounds

Meridian College sat in a river city that pretended to be smaller than it was. Brick halls, a clock tower that ran four minutes fast, a science annex that had been added in a decade when money existed and then neglected in every decade after. Students called the annex the Greenhouse even though nothing green lived there except the mold behind the autoclave.

Rong Xi had arrived in January, mid-year, from a coastal city on the other side of an ocean. The official story in the student paper was exchange-plus-transfer, materials science track, sophomore standing after credit evaluation. The unofficial story, which Caleb pieced together later from club flyers and the way she said home like it was a laboratory she had misplaced, was that she had petitioned three departments and one very tired dean until someone gave her a bench and a key.

She ran the club the way some people ran kitchens: loudly, generously, with a private system that made sense only after you had burned yourself once.

Caleb’s next class passed in a smear of charcoal and half-heard critique. He packed his bag wrong. He took the long way to the annex so he could tell himself he was still deciding.

Lab Three’s door was propped with a rubber stopper. Inside: wooden benches scarred by a generation of clamps, a forest of ring stands, colored wires in lazy coils, flasks of blue solution that were probably just copper sulfate and looked like magic anyway. Microscopes stood like small observatories. The windows were high and dirty-bright. A chalkboard at the back held a diagram that might have been a polymer chain or a subway map.

Rong Xi sat on the nearest bench as if it were a sofa, legs slanted, loafers dangling, the burgundy sheet held up in both hands like a flag she had not yet decided to claim. She looked back over her shoulder when the door clicked. One eye closed in a wink. The grin was the same library grin, relocated to a room that suited it better.

“You came. Good. The landing can still be saved.”

“I had time,” Caleb lied.

“Everyone has time. Few people spend it on a girl and a piece of rubber. Sit. Not on the stool with the short leg. That one hates strangers.”

He sat on a different stool. She stretched the burgundy sheet between her fingers. It thinned, went translucent at the edges, snapped softly back.

“This is batch R-14,” she said. “Burgundy because I like colors that look like they have a secret. The base is centrifuged latex, not the cheap ammoniated stuff from the art store. I add a vulcanizing paste I mixed myself. Zinc oxide, sulfur, a little accelerator I am not supposed to keep in a dorm fridge. The pigment is iron oxide and a touch of quinacridone so it does not go brown under fluorescent light. Thickness is uneven on purpose. Uneven thickness is how you get a balloon that remembers being a person.”

“A person.”

“You know what I mean.” She didn’t look like she knew whether she meant it. “Soft where it should yield. Stubborn at the neck. If you blow too fast it punishes you. If you are patient…”

She hopped down, then up onto a different stool, closer to him, and put the sheet to her lips.

The first breath did almost nothing. The rubber pouted. Rong Xi’s cheeks hollowed. A faint flush rose along her cheekbones. She held the neck with both hands, thumbs careful, and pushed air in as if she were arguing with it in a language made of lungs.

The burgundy gathered itself.

It became a small plum, then an apple, then something that had opinions about being held. The surface went from matte cloth to skin: taut, glossy, a highlight sliding across the curve like a moving thought. Rong Xi’s eyes widened. A bead of effort stood at her temple. The balloon grew past the size of her head, past the size of a melon, trembling with each added breath, the neck vibrating in her fingers.

Caleb forgot to pretend he was not watching her mouth.

She pulled off, gasping a laugh, and the balloon bobbed between them, already large enough to need two hands. “See? It chooses. This batch likes a round. Last week’s liked a teardrop and then died of vanity.”

“Died.”

“Popped. Same thing if you are a balloon.” She wiped her lip with the back of her wrist, still smiling, a little pinker now. “Your face is very funny. You look like I am performing surgery.”

“You kind of are.”

“Good. Surgery should be watched.” She offered him the neck. “Your turn. One breath. Do not be heroic. Heroic bursts things.”

Caleb had not planned to put his mouth where hers had been. He did it anyway. The rubber tasted faintly sweet and faintly of chalk. The resistance was immediate, intimate, a living no that became a yes only if you committed. He gave it one careful breath. The sphere swelled another inch. His ears felt hot.

Rong Xi took it back as if he had passed a test he had not known he was taking.

“You don’t overblow. Rare. Most boys treat a balloon like a dare.” She tied the neck with a practiced twist, a little grunt of effort, then held the finished globe up. It was the color of wine held to a window. “R-14. First successful sphere of the afternoon.”

“What do you do with them after?”

She looked at him over the curve. “That,” she said, “is a second-date question.”

“This isn’t a date.”

“Not yet.” She set the balloon on the bench. It rolled half an inch and stopped against a flask. “I have office hours that are not office hours. Thursdays, this room, until the building closes. You may come and draw. I may talk about modulus and why people are afraid of things that shine. We will see if your rooftop girl learns how to land.”

Caleb should have said he was busy. He heard himself say, “Thursday.”

Rong Xi kicked her heels against the stool, pleased. The navy skirt shifted. Afternoon light made a cheap halo on the burgundy sphere.

Outside, the clock tower told the wrong time, as always.

Chapter Three

How to Hold a Conversation About Balloons

Thursday became a habit before either of them named it.

He learned the geography of her world in pieces. The club had six members on paper and two who actually appeared. The bench by the window was hers. The mini-fridge labeled DO NOT contained more vulcanizing paste than food. She kept a notebook with swatches of color taped to the pages and burst-pressure numbers written in a tight hand, English mixed with characters he could not read.

She learned that he was a junior in illustration, that he worked nights at the campus copy shop, that he had started the rooftop girl three years ago as a webcomic and then gotten scared of finishing anything people might see. She learned this because she asked, and then asked again when his first answers were small.

Their conversations did not stay on balloons. They kept returning to balloons the way a compass returns to north.

“People think fetish is the only reason an adult would care,” Rong Xi said one Thursday, sitting on the bench with her loafers braced on a lower rung, spinning an uninflated teal sheet around one finger. “Sometimes it is. Sometimes a thing is beautiful and your body notices before your manners do. I am not going to lie to you and say I only love the chemistry.”

Caleb, who had been shading a panel of the rooftop girl finally landing, paused.

“I like the sound,” she continued, almost clinical, almost not. “The creak when the wall thins. I like that it can hold me if I make it strong enough. I like that it is ridiculous and still serious. You can sit on a theorem. You cannot sit on most theorems.”

“You sit on them.”

“I test load-bearing. It is science.” Her mouth twitched. “Also it is fun. Fun is allowed in science if you write it down afterward.”

He laughed, surprising himself. She looked delighted to have caused it.

They ate convenience-store onigiri on the fire stairs. She told him about the first balloon she ever bought, a cheap red one from a night market, how it had wilted overnight and how she had decided wilt was an engineering problem. He told her about the first comic he posted and then deleted. She said deletion was also an engineering problem.

Once, in the library again, she leaned over his shoulder and corrected a fold of fabric on his drawing with a fingernail, not quite touching the screen.

“Your girls are getting heavier,” she murmured. “Good. Weight is honesty.”

He did not tell her he had started drawing from a new reference.

He did not have to.

Chapter Four

The Burgundy One

The afternoon she decided R-14 needed to go further, the annex was almost empty. A seminar had eaten the other club members. Rain pressed the high windows. The fluorescents hummed.

Rong Xi sat on the stool with one knee hooked high, the way she sat when she was about to be stubborn, and inflated the burgundy sheet past the size they had stopped at before. Past a beach ball. Past polite. The sphere crowded the aisle between benches, reflecting microscopes, reflecting her white shirt, reflecting Caleb standing there with his phone forgotten in his hand.

Her breath came in counted pushes. Cheeks flushed. A shine of effort at her lip. The balloon’s skin grew so thin the overhead lights bloomed inside it like drowned stars.

She pulled off, panting, eyes wet with the simple animal brightness of having done a difficult thing.

“If I keep going it will take the ceiling,” she whispered, half joke, half wish.

“Don’t.”

“You say don’t like you are the safety officer.” She laughed, then sobered, palms sliding along the curve as if greeting it. The balloon answered with a low rubber complaint, a sound like a floorboard in an old house. “Feel.”

He did. The surface was warmer than he expected, tight as a drum, trembling with the last of her breath still equalizing inside. His hand looked large and clumsy on it.

“This is the part people do not draw,” Rong Xi said quietly. “The almost. The balloon that has decided not to die yet.”

She hopped onto the bench itself, skirt whispering, and cradled the enormous burgundy globe against her side. From that angle she looked smaller and the balloon looked like a planet she had stolen. Her mouth opened. A soft sound of awe. One hand stayed on the curve; the other hovered as if the air around it might bruise.

Caleb, without asking, took a picture. Then he felt like a thief and showed her the screen.

She studied it, head tilted. “My face is stupid in this one.”

“Your face is—” He stopped.

“Say the sentence.”

“Your face is the point,” he said, and immediately wanted the floor to open.

Rong Xi’s smile went smaller and better. “Okay. Keep that one. Draw it later. Draw the almost.”

She deflated the giant carefully, hissing air out in a controlled sigh so it would not scream. The burgundy collapsed into a wrinkled skin again, intimate and spent. She folded it as if folding a letter.

“Next week,” she said, “if the tensile numbers hold, I make one you can sit on.”

Caleb’s throat did an unhelpful thing.

“Load-bearing,” she added, innocent as a knife. “Science.”

Chapter Five

Members of a Club of Two

The campus noticed them the way campuses notice anything: sideways.

A girl from Drawing II asked Caleb if the transfer in the baby-blue lab coat (Rong Xi did not own a baby-blue lab coat; rumor had invented one) was his girlfriend. He said no and then walked around for an hour feeling like a liar for no legally relevant reason.

Rong Xi, for her part, introduced him to the club’s group chat as “Caleb, who draws the landings,” and then sent a photo of his rooftop girl with the caption progress. He had not given her the file. She had photographed his phone while he bought drinks from the vending machine. He sent back a sticker of a man screaming. She sent back a sticker of a balloon.

They studied together once in the student union and it was a disaster of a different kind: too many people, too much noise, her knee knocking his under the table every time she laughed. She talked with her hands. She stole his fries and replaced them with a lecture on why potato starch would make a terrible balloon film.

“You could try,” he said.

“I have tried worse.”

That night he opened a new layer and sketched her from memory: bangs, the particular slope of her smile, the way the white shirt strained a little at the second button when she inhaled to explain something. He did not draw the balloon. He drew the space where one would be.

He saved the file as `do_not_post.psd` and then sat on his dorm bed staring at the filename like it had accused him.

Chapter Six

Mounted

The day the load-bearing balloon lived, Lab Three was not enough room.

Rong Xi had booked the old process bay in the annex basement—an industrial leftover full of stainless columns, catwalks, and glassware that belonged to research groups who no longer remembered they owned it. The air down there was cooler. Lights hung in long white bones. Everything smelled of metal and old solvent and the sweet edge of fresh latex.

The burgundy thing on the floor was not a party balloon. It was a swollen, glossy continent, low and huge, skin so polished it held warped reflections of tanks and test tubes. It had the lazy animal shape of something that had been a perfect sphere and then yielded, happily, to gravity and to the idea of being sat on.

Rong Xi stood beside it with her hands on her hips, surveying her work.

“R-14-LB,” she announced. “Walls at two-point-one millimeters at the pole, thinner at the equator because I am a show-off. Theoretical seated load: more than me. Practical seated load: we are about to find out. If it bursts, you will pretend you were not here, and I will pretend I died doing what I loved.”

“That’s not funny.”

“It is a little funny.”

She stepped onto it.

The balloon took her weight with a deep, groaning flex. Burgundy sides bulged. Rong Xi’s laugh broke out of her, startled and delighted. She sank, knees spreading for balance, navy skirt riding, white cotton underneath flashing in the gap as she settled astride the curve like a rider who had never seen a horse and did not care. Loafers found the floor on either side. White socks. The balloon breathed under her, a slow rubber pulse.

“Oh,” she said, very softly. “Oh, that’s—”

Caleb had forgotten how to put his hands in his pockets.

She looked at him from that ridiculous throne, cheeks pink, bangs slightly stuck to her forehead, and threw him a peace sign with her right hand as if this were a postcard from a place that should not exist.

“Science,” she declared.

“Science,” he repeated, uselessly.

She bounced once, experimentally. The balloon complained in a register that went down his spine. Her skirt lifted and fell. She was not trying to be obscene. She was also not trying not to be. The distinction lived in the shine of her eyes: I know what this looks like. I made it look like this on purpose. I am still going to call it data.

“Come closer,” she said. “If you stand over there you will draw me like a statue. I am not a statue. I am a person sitting on a disagreement with the atmosphere.”

He came closer. The process bay made their voices small.

Rong Xi shifted, finding a seat that made the balloon dimple. “You can touch it. Not me. It. Unless you ask, and then we will have a different conversation in a different tone of voice.”

He set his palm on the warm taut skin near her knee. The vibration of her small movements traveled through the rubber into his bones.

“Good?” she asked.

“Yeah.”

“You are a terrible liar when you are overwhelmed. It is one of your best qualities.” She peeked at him through her fingers, peace sign becoming a silly mask over one eye, grin lopsided. “Draw this. If you draw this timidly I will know.”

He drew it later, in his room, with the door locked for no adult reason. He drew the columns. He drew the gloss. He drew the honest weight of her thighs and the white edge of cotton and the peace sign and the fact that she was looking at the viewer as if the viewer had been invited.

He did not post it.

He sent it to her at 1:12 a.m. with no caption.

She replied at 1:14:

the landing is correct

thursday same bay if the seals hold

also i liked that you did not make my legs thinner. do not ever do that.

He lay on his back and smiled at the ceiling until the smile got embarrassing even though no one could see it.

Chapter Seven

Playful Banter, and the Other Thing Under It

They became, without a press release, a pair of people who ate together.

Caleb learned she took her coffee with too much sugar and defended the choice as “fuel for vulcanization.” She learned he could not watch horror movies because the sound design made his hands want to draw the monster instead of the fleeing person. They argued about whether a balloon was more like a drum or more like a lung. They argued about whether his rooftop girl should have a name. Rong Xi suggested names until he agreed to Lin, then immediately proposed Lin should meet a balloonist and refused to drop it.

“Cameo,” she said, stealing his last dumpling. “A girl on a roof, a girl on a balloon. Same gravity. Different negotiation.”

“That’s not how genre works.”

“Genre works for me.”

On a Wednesday they got caught in rain between the union and the annex. Rong Xi refused his jacket, then accepted it, then complained it smelled like toner, then walked closer so their shoulders matched weather. Her hair stuck in dark lines to her neck. She looked less like a character sheet and more like a person who had decided to be soaked on purpose.

“In my first language,” she said, watching the gutter flood, “there is a word for the shine on something stretched. Not wet. Not new. The shine of tension. I cannot find it in English. I have been using gloss and it is not enough.”

“You could teach me the word.”

She did. He pronounced it badly. She made him say it until the rain felt like an excuse to keep standing there.

That night he added a small panel to the comic: Lin on the rooftop, looking down, seeing something round and dark and shining in an alley, captioned only with the word Rong Xi had given him.

He still did not post.

The want between them was not subtle anymore. It lived in the extra second she held his eyes. It lived in the way he noticed the second button of her shirt. It lived in the balloon, which had become their private dialect: stretch, hold, almost, yield.

She never pretended the hobby was only academic. He never pretended he was only documenting.

When she asked, once, sitting on the smaller classroom balloon in Lab Three with her skirt doing what short pleated skirts do, “Does this bother you?”

He said, “It bothers me in the direction I like.”

Rong Xi went red to her ears and then laughed so hard the balloon squeaked.

“Okay,” she said. “Then we continue.”

Chapter Eight

Bigger Than the Room

R-14-LB’s successor was an act of cheerful arrogance.

She built it over two nights, mixing pigment until the burgundy went from wine to something wetter, almost edible. She talked while she worked. Caleb handed her clamps and tried not to think about how domestic it felt, two people in an empty bay making a ridiculous planet.

When they inflated it with the filtered compressor she was allowed to use after filing three forms, the balloon grew until it occupied the aisle like a landed animal. Low. Wide. Gloss shining under the long lights. Large enough that when Rong Xi climbed on, her legs could not close. She sat in the saddle of it, peace sign already rising, white undershorts a frank little flag, loafers planted wide on the tile as if she were bracing for takeoff.

“Do not look away,” she said, and it was not only teasing.

He didn’t.

The balloon took more of her than the last one had. It swallowed her seat, hugged the backs of her thighs, made a sound like a held note. Rong Xi’s breath hitched. For a second the science-club president vanished and there was only a girl feeling something she had engineered specifically so she could feel it.

Then the grin came back, wicked and shy at once.

“Write in your notes,” she said. “Subject is stable. Subject is showing off. Subject would like the artist to stop standing like a coat rack and come here.”

He went.

Up close the rubber smelled like her work and a little like her skin. She took his hand and placed it on the balloon beside her hip, not quite on her, a border they could both see.

“This is still a conversation about balloons,” she whispered.

“Is it?”

“It can be two conversations at the same time. I am very talented.”

He kissed her.

It was not a cinematic kiss. It was a slightly off-center, rain-remembering, finally kind of kiss, and the balloon under her gave a shocked little groan as she leaned into him. Rong Xi made a noise into his mouth that he would later refuse to classify as data.

When they separated she kept her forehead against his.

“Good,” she said. “The landing is correct.”

Chapter Nine

What Went From a Light-Hearted Intrusive Greeting

They dated the way students date when they already have a shared room full of dangerous hobbies: badly scheduled, intensely, with too much walking across campus in weather.

He posted the webcomic.

Not the drawings of her. Those stayed in the folder called `do_not_post`, which he renamed `rong_xi` because lying to a filename was beneath them now. He posted Lin, the rooftop, the rain, the small shining thing in the alley. A modest number of people liked it. One comment said the physics of the landing were surprisingly good.

Rong Xi screenshotted the comment and sent it with twenty balloon emojis.

The club gained one more actual member, a first-year who wanted to make biodegradable party décor and who treated Rong Xi like a minor prophet. Rong Xi taught the first-year to never cheap out on the neck. Caleb sat in the corner and drew and was occasionally used as a sandbag when something needed to be held down.

On a Saturday in late term they took a cheap balloon—store-bought, red, beneath her standards—up to the clock tower stairs and let it go just to watch it fail against the bricks. Rong Xi declared the failure educational. Caleb declared her educational. She elbowed him and then held his hand with the determination of someone who had decided holding hands was also a tensile test.

“In the library,” she said, “I almost did not stop. I almost walked past. You looked like you wanted to be a wall.”

“I’m glad you didn’t.”

“I know. I am very wise.” She bumped her shoulder into his. “Wanna chat was a stupid line.”

“It worked.”

“It worked because you are the sort of person who answers stupid lines. Do not change that. I have more stupid lines.”

He believed her.

---

Chapter Ten

Coefficient

Finals arrived and tried to ruin everything, as finals do.

They survived in the process bay and the west stacks and a twenty-four-hour diner that served eggs that tasted like the grill they were born on. Rong Xi wrote a paper on elastomeric hysteresis with a straight face. Caleb turned in a portfolio that included, on the last page, a study of a girl sitting on a dark sphere, cropped high enough to be allowed and honest enough to be her.

The professor wrote strong sense of volume in the margin.

Rong Xi, reading it over his shoulder, whispered, “Volume. He has no idea.”

On the last night before winter break, the campus emptied into suitcases. Snow started, undecided. Lab Three’s radiator clicked. One burgundy balloon, medium, well-behaved, sat tied to a ring stand like a pet.

Rong Xi perched on the bench in the same white shirt, same navy skirt, same socks and loafers, as if the character reference had followed her into the real year. She held his hand in both of hers and swung her feet.

“I am going home for three weeks,” she said. “Home is loud. I will send you photos of night-market balloons that will disappoint me. You will send me panels. We will not pretend we are casual.”

“Okay.”

“Also.” She looked at the tied balloon, then at him. “When I come back I want to make a clear one. See-through. Harder chemistry. If it works, you can see the air. If it works too well, you can see me being ridiculous on purpose. I am warning you now so you may practice your face.”

Caleb practiced his face. It did not help.

She kissed him again, softer than in the bay, and then flicked the burgundy balloon so it bobbed.

“A thin skin holding a disagreement with the atmosphere,” she said. “That is still the definition. It is also, inconveniently, a definition of dating.”

“That’s the worst metaphor you’ve made.”

“You will quote it later when you are trying to be romantic. I know your type. You draw girls in the air and then you look for someone who can teach them gravity.”

He could have argued. He put his forehead against hers instead.

Outside, the clock tower told the wrong time.

Inside, the balloon shone, patient, holding its breath for as long as the knot would allow.

Epilogue

Clear Intent, But a Life for Two

In spring, a clear balloon occupied the process bay for exactly eleven minutes before Rong Xi declared the batch a beautiful failure and started the notes for the next one. Caleb sat on the floor with his back against a column and drew her standing in the wreckage of shine, laughing, hair full of static, already reaching for the next sheet of unformed color.

On his phone, between the panels of Lin and a photo of a night-market stall she had sent at an hour that made no sense in either time zone, there was still the first picture: a sophomore on a library Thursday, except it wasn’t the library. It was a girl on a bench holding a wrinkled burgundy square up to the light, one eye closed, asking a question that had not belonged in a quiet place and had built a louder one.

Wanna chat?

He had. He still was.

The landing, at last, had weight.
