Sharing Scars

pairing: beefy grumpy!bucky barnes x sunshine!reader (soulmates au)

warnings: mentions of torture/pain, soulmate bond that shares injuries, emotional intensity, angst with comfort, soft tenderness, mutual pining, fluff in the end.

summary: You’ve spent your whole life carrying Bucky’s pain—every Hydra scar, every mission injury, every break in his body echoing in yours. Careful to the point of smallness, you swore you’d never add to his burden. But when fate drops you into the Tower’s medbay, the man behind all those phantom aches finally stands in front of you—and he isn’t ready for the truth you’ve been holding all these years.

a/n: inspired by this ask. i loved everything about it. immediately locked in to get this written out like it deserved 🥹💛

------------

You learn to count time in pain.

Not the ordinary kind—stubbed toes or paper cuts—but deep, bone-dragging pain that drops like a storm out of a blue sky, leaving you breathless and clutching the edge of the kitchen counter while the kettle screams. It starts when you’re small. You’re tracing the outline of a sun on construction paper and your wrist burns as if someone pressed a brand to the inside of it. You cry. Your mother doesn’t tell you it will be okay. She holds you and says, in the voice she keeps for truths that don’t bend, “Your soulmate must be very brave.”

You don’t know what “Hydra” is. You don’t understand the hiss of electricity you sometimes taste at the back of your tongue, the static that makes your hair lift before the pain crashes down. You only learn to breathe through it. Count. In. Two. Three. Four. Out. Two. Three. Four. The first language you become fluent in is not English; it’s endurance.

By twelve, you’ve got a system. Ice packs in the freezer. Soft clothes. Sneakers unlaced but ready by the door in case you have to pace the hallway at three a.m. to convince your body it’s yours. You keep a notebook that looks like it should be full of heart doodles; it’s filled with dates and symptoms, a crude map of someone else’s suffering laid over your growing-up years. You get good at noticing the patterns. There’s no point asking why. The why hurts almost as much as the when.

There are months that feel like mercy. Weeks where your life is ordinary: school, hot chocolate, friends who tease you about the way you patch them up after PE like a one-girl med tent. It’s always been there, that impulse. If someone’s scraped a knee, you are half a step ahead with antiseptic and steady hands. Your teachers write “calm under pressure” on your report cards. You shrug. They don’t know that pressure lives in your marrow like weather.

You decide early: if your soulmate is going to live a life like this, you will build a life that can help him. You won’t drag him under with your pain. You’ll be careful—hyper-careful, the way other people are with words they only say once. You keep to sidewalks. You clip your nails. You never push a dull knife through a tomato. Your high school friends call you “grandma” because you keep band-aids in a silver tin and text to make sure everyone gets home safe. You smile and let them laugh because this is the only way you know to love a stranger: become a place that doesn’t hurt.

You work, study, volunteer at the free clinic even when the head nurse warns you the hours will wring you dry. You learn to read vitals like sentences and stitch skin like you’re coaxing something holy back together. When pain hits—sharp, crushing, electric—you excuse yourself, breathe behind a door, splash cold water, return. Patients call you sunshine. You don’t feel like light, not really. You feel like a glass lamp with a storm inside it, but you’ve gotten good at making the outside glow.

You hear his name before you meet him like a rumor in a language you almost understand. James Buchanan Barnes. Sergeant. Assassin. Avenger. Ghost. The way people say it, you could believe he’s a half-made myth wrapped in a man’s body. You watch grainy footage once, because you think maybe you should know what his shadow looks like if you’re going to spend your life holding its weight. He moves like he’s been taught to be both bullet and bruise. He doesn’t look at the camera. He never looks at the camera.

When you get the offer—the Tower’s medbay is hiring, the pay is good, the benefits are better, and the NDAs would make your law professor weep—you read it three times and put the phone down. The Tower. A job where your carefulness might matter; where your quiet hands might do something for the man who’s been hurting you by accident since you traced suns in crayon. You don’t know if he’s there, if he exists the way the headlines claim, if he’s healed or breaking or in between. You only know that your chest says yes so fiercely it feels like a door blowing off its hinges.

New York is less myth and more noise than you expect. The Tower is glass and steel and gravity; it’s also the medbay coffee machine that sputters like a sleepy dragon and a stash of mismatched mugs, three of them chipped. Dr. Cho is as brilliant as the stories promised and almost unnervingly kind. She looks at you the way she looks at the bioregenerative cradle: as if you’re a technology worth understanding. “We do medicine differently here,” she says on your first day, and she isn’t talking about equipment. “We don’t treat the body as separate from the person who lives in it.”

“Good,” you say softly. “I don’t either.”

The first time you hear his voice, you’re inventorying suture kits. It isn’t a dramatic entrance. No alarms. No sprinting down gleaming hallways, no blood blooming across floor tiles. It’s the slow murmur of a debrief drifting through the medbay door someone propped with a lab stool. He doesn’t sound like a ghost. He sounds… tired. Kidding, a little, around the edges, the way people bargain with exhaustion. Someone laughs—Sam Wilson, probably, that warm rasp—and then a lower rumble says, “I’m fine,” and your lungs forget their job. Pain doesn’t spike. That’s new. That’s alarming. That’s relief so sudden it feels like a bruise pressed and found not tender.

You don’t see him. You don’t need to. You sink onto a stool and wrap your hands around your own wrists until the urge to go to the doorway and look—just look—passes. You’ve spent years not chasing pain. You can give yourself one day not chasing a man.

It turns out to be three days, because life is busy and the team rotates through like weather systems: in, out, sometimes dropping with laughter, sometimes with the hard silence of missions that didn’t go the tidy way. You keep their secrets like stitches—neat, small, essential to healing. You make sure there’s always a clean blanket folded on the end of the cot that faces the window. You set aside the mugs that get used most. You learn Natasha’s tell for “don’t ask.” You become very good at saying, “I’ve got you,” and meaning it.

When you finally do see him, it’s not heroic. It’s a Tuesday. You’re rewrapping Clint’s wrist because the idiot archer has decided his tendons work better if wrapped in stubbornness. The door opens. The air changes. You don’t look up because you’re a professional. You tell Clint to stop using his injury as an excuse to avoid dish duty and tie a tidy knot with your teeth while you reach for tape.

“Barnes,” Clint says, because he’s a menace. “Make the sad eyes at her; maybe she’ll guilt-release me.”

“Not a chance,” you say, and glance up on the smile, and that is how you meet the man who has taught you your own pain.

He is larger than the headlines made him. Not in height—though he’s that too—but in presence, like a storm-tossed ship that has decided to be harbor instead. His hair is longer than you’d expected, his mouth softer, his shoulders—God, his shoulders. The synthmesh shirt he’s wearing gives you every detail you don’t deserve. He’s carrying a bruise on his cheekbone like he’s done this before and will do it again.

“Hey,” he says, slow, as if the word might shatter if he isn’t careful. His eyes find you, and something at your breastbone loosens without permission. The thing about learning someone in pain is that you can tell when they aren’t. Today, right now, he isn’t. You exhale a smile you didn’t know you’d been holding.

“Hi,” you return, equally gentle. You will not drop the room into reverence because a man with a tragic dossier walked through the door. You will not orbit him like he’s gravity. You will thread this moment into the cloth of the day, and see if it holds.

“I need a quick look,” he says to the room in general, and to you specifically he adds—almost apologetically—“I took a hit. Nothing big.”

Clint makes a noise that means “define big.” You pat his wrist and say, “I’ll trade you out with Dr. Cho and check Mr. Nothing Big. We’ll see which of you wins the ‘most dramatic patient’ medal this week.” Clint huffs and you stand, finally, on legs that feel steady because they remember what steady has been for years.

“Sit,” you tell the soldier you’ve never touched, and he obeys so instantly it’s almost a prayer. You take in the details that matter: blood at the shoulder seam, sluggish, just enough to tell on itself; a rip at the shirt that’s more resigned than angry; the set of his jaw like he’s holding a drawer closed with his knee while the contents lean hard against it.

“Arm?” you ask, reaching out, hovering your fingers over the metal. He nods. You lift. The weight is mercifully familiar because you’ve trained on the Tower’s simulators; the heat is real and particular. He watches your hands, not your face. You don’t mind. You’ve always known people from the outside in.

The wound is ugly and simple—shrapnel tore a crescent low along his deltoid. It should have felt like your body was being carved open while you slept or ate cereal or argued with insurance forms, but it didn’t. You felt a echo, maybe, last night: a tug, a silent alarm. Not the old lightning. Not the chair.

You’re cleaning it when you see the scar.

At first it’s just another pale seam among many on his shoulder, a crisscrossing atlas of old maps. Then your vision tips, tilts, and your hand goes still. There’s a crescent there, almost the same path as the wound you’re treating, and another line that forked off it years ago, long-healed—no, not years. You know it like you know your own heartbeat. You know it because sometimes you scratch at your upper arm in the shower not because it itches but because you’re remembering something that never touched your skin. You saw this scar once, with your fingers. It was the first time he survived long enough for the wound to become a story. You bled for it and then you didn’t.

He shifts, and the world comes back. You have to breathe, remember? In. Two. Three. Four. Out. Two. Three. Four. You finish cleaning, wrap, tape, and only then, only when the practical magic is done, do you say, “You’re okay.”

He huffs. “Define okay.”

“Alive. Not leaking. Clear for lunch if you promise to actually chew.”

It startles a laugh out of him, rusty and perfect. He lifts his eyes. You shouldn’t have been unprepared; you’ve been preparing for this your whole life. But there’s something about the color—lake-water in shadow, a bruise after the sting fades—that lands in your throat. You could drown there and not mind.

He sees your reaction. He sees everything. His expression changes in a way you’ll learn means he’s thinking about something dangerous like you’re a safe place to put it. “Have we met?” he asks softly, like he’s already sorry for taking a piece of you with the question.

“No,” you say, and it’s true. It’s also the closest thing to a lie you’ve ever told. You swallow, choose gentleness, choose truth that fits in your mouth. “I’m new. First week.”

“You’re good,” he says, as if he’s been doing this long enough to know. He flexes the arm experimentally and doesn’t wince. You watch relief move through him like light. You try very hard not to cry.

“Eat,” you say, because you’ve used up your bravery for the hour. “And come back tomorrow so I can admire my work.”

“Order, huh?”

“Suggestion,” you amend, and then because you’ve been living careful for so long you’ve forgotten what it feels like to let a door swing open, you add, “I make good coffee. As a bribe.”

His mouth does a thing you will think about later, when the city is quiet. “I’ll take it,” he says. “The coffee. And the bribe.”

He leaves. You stand in the middle of the medbay with your heart beating like it’s relearning tempo. Clint slings his legs off the cot and smirks. “So,” he says, “you gave the Winter Soldier a juice box and told him to chew. Bold strategy.”

You make a face and flick his chart. “Go. You’re cleared. But if you open that jar of pickles with your wrist again, I’m telling Natasha.”

You don’t intend to get hurt. You never do. Being careful is your religion. But life, with her crooked sense of humor, likes to test faith.

It happens on a Thursday two months later. The team is out. The medbay is quiet. You’re stocking gauze on the high shelf you shouldn’t be using because you’re five-six on tiptoe and this is a job for someone with a ladder. You tell yourself to be sensible. You tell yourself not to reach. You reach. The metal box shifts. You catch it. Victory, you think, and then the corner kisses the back of your hand with enough enthusiasm to leave a mouthful of glass.

It’s small. It’s nothing. It’s the sort of cut you could put a cartoon band-aid on and call it character-building. You stand there, watching bright blood well up like your body is surprised by its own richness, and you feel something you haven’t felt in a very long time: terror so swift it edges into shame.

You do not hurt him.

You move on instinct. Sink to the stool, grab gauze, clamp down, breathe, breathe. It’s fine. It’s barely anything. You are overreacting after a lifetime of training yourself not to. You sit there counting seconds until the hot panic cools to embarrassment, and then the door slams open so hard the stool skates under you and crashes into the cabinet.

“Where?” Bucky demands, and he’s across the room before you can assemble words for his face. He looks wild. Sweat slicks his temple. There’s road-dust in his hair and blood on his knuckles and a kind of grief in his eyes you have seen before—from the inside.

“Where,” he says again, softer, as his hands find your hands. He pulls your fingers away from the gauze with care that makes you dizzy. When he sees the cut, the relief he lets out is almost obscene, like he’s been holding his breath under a long wave. His thumbs tremble at your wrist. “You,” he says, and the word is as full as prayer. “You. It was you.”

You don’t realize you’re crying until he makes the soft noise people make when they find a fragile animal and want to prove they won’t hurt it. He looks up at you and doesn’t look away. He doesn’t look away.

“I felt it,” he says, simpler than the ownership brand you’ve both been living under. “On the bike, it hit me so hard I thought—” He stops, swallows. Tries again. “I’ve been feeling things for years I couldn’t name. And then months of quiet, like someone was trying not to breathe too loud. I thought I was going crazy or getting better or both. And then this, just now, like a firefly sting, and I knew.”

You laugh, wet and breathless. “Firefly.”

“Don’t make fun of me; I have a limited bug vocabulary.”

He is shaking. So are you. You reach up and touch his face—first time, first real time—and his eyes close like the light’s too bright. His skin is warm. He leans into your palm the way a man leans into a lighthouse in the middle of a ruin. “Hi,” you whisper, because you don’t know what else to do with a moment this large.

He opens his eyes. His hand comes up to cover yours at his jaw, large and steady. You can feel the edge of a scar under the pad of your thumb, the fine, faint seam you traced once with shaking hands while he slept on a cot three rooms over. He lifts your palm enough to kiss the heel of it and the world tilts.

“I’m sorry,” he says, and the apology is too big for the room. “For all of it. For… Christ, you’ve been—how long?”

“All of it,” you echo, but your voice is gentle. “Don’t be sorry you were alive.”

He makes a hurt noise and laughs at the same time. “You sound like Cho.”

“I’ll take that as a compliment.”

“It is.” He swallows. “I kept thinking I had a guardian angel. Or a ghost. Or—” He looks down at your hand again, at the careful little crescent of red sealing itself at the edges. He is not horrified by blood; anyone can see that. He is horrified by this: that his life might land anywhere near yours with sharp corners. “You were careful,” he says, and it’s not a question. “I can feel it. Now that I know, I can feel—there’s space where there shouldn’t be. You made a quiet place out of yourself.”

You laugh again, crooked. “I didn’t want to hurt you.”

He lifts his head. For a long time he just looks. “You can, you know,” he says quietly, because he’s Bucky Barnes and he’s braver than grief made him. “If you want to live. You can stub your toe and burn your tongue and climb a stupid ladder and—” He inhales, wincing like the truth costs him. “I don’t want you small. Not for me.”

The careful thing would be to nod. To say you’ll think about it. To promise a theoretical you freedom tomorrow while you keep yourself wrapped in bubble wrap today. But you are holding his face and his hands are holding your hands, and you have been breathing around this man for years without the words for him. The truth falls out: “I want to be brave in ways that don’t break you.”

He kisses you like an answer.

It isn’t a cinematic kiss; the medbay doesn’t swell with music. It’s clumsy—both of you shaking, both of you a little stunned. But his mouth is warm, and he is careful in a way you understand down to the cell. He is careful the way you have been. He cups the back of your head. It’s not a collision; it’s an opening.

When you pull back, he presses his forehead to yours and exhales. “I won’t always be good at this,” he warns, like you haven’t read the manual written on your own nerve endings. “I’m grumpy. I get it wrong. I—”

“Me too,” you say, so fast and fervent that his laugh chokes. “I’m soft, not stupid. And I’m not here to fix anything. I’m here to be with you while you fix it yourself.”

He is very still. You can feel him rerouting the way rivers reroute after a landslide—slow, hungry, unstoppable. He nods. His hand is still on yours, both of them, metal and flesh, and the balance of them might be your favorite thing you’ve learned so far. “Okay,” he says. “Then be with me while I do this right.”

He kneels.

It’s not a proposal. You’re not ready for that, and he knows it. It’s something older. He’s always had a soldier’s instincts for ritual, and this is one: he kneels, taking your hand in both of his like it’s a flag he’s been carrying too long and is finally returning to its rightful owner. He flips your hand gently so the back faces up. He studies the small, fresh cut the way he studied maps once. He leans in and kisses beside it, not on it, and when he looks up again there’s a wet shine in his eyes he isn’t ashamed of.

“Matching scars,” he murmurs, the words slow with reverence. “A story only we know.”

You breathe out a laugh that doesn’t hurt. “You’re getting poetic on me, Sergeant.”

“Don’t tell anyone,” he says, and stands, and kisses you again like he likes you. Like he will like you in the mornings and the messy middles. Like the bruise-color in his eyes is light coming back, not leaving.

You learn quickly what the Tower already knows: Bucky Barnes is grumpy like a cat is grumpy—performative, selective, deeply amusing when you know the tells. He is also gentle like gravity is gentle: constant, inescapable, the thing that pulls you home. He looms, sure, but it turns out that looming can be a love language. He has to get used to you swatting at his chest when he tries to open your doors for you, not because you don’t like chivalry but because you have hands and you’d like to use them. He has to get used to you laughing in his mouth when he glowers at Tony for teasing you, because the teasing is affectionate and you can handle affection. He has to learn that if he scowls at your coffee mug and says, “You should drink water,” you will hand him a matching mug and say, “You should drink water,” and then you’ll both drink water and pretend you won something.

He worries. You don’t mind. Worry is another word for “I know what it is to be powerless, and I refuse to be indifferent.” He touches your shoulders to feel that you’re solid. He watches you walk down stairs like the stairs have offended him. He loves you with his body like a fortress and with his mouth like a promise. He learns to say “I’m taking a walk” when pain flares, and you learn to say “I’ll come with you” or “I’ll be here when you get back” depending on which kind of alone he means.

The team, of course, knows before either of you is ready to make speeches about it. Natasha gives you a clean nod that means welcome to the club of women who will set the world on fire to keep our boys warm. Sam hugs you once and mutters, “Thank you,” hot and awkward into your hair. Tony pretends to be scandalized and then pesters Bucky with a PowerPoint called “Safe Practices for Pain-Linked Partners,” which includes, among other gems, a slide that reads DO NOT DO ANYTHING DUMB, BARNES, with an animated arrow pointing at your face labeled ALSO YOU.

You live anyway. That’s the point. You stub your toe on the medbay stool and you both yelp and end up on the floor laughing so hard you scare the interns. You burn your tongue on pizza and he licks his own on reflex and makes a betrayed noise so theatrical you cry with laughter. You trip on a curb and he catches you and then trips with you because momentum is a law and the two of you grinning on the sidewalk like a PSA about joy is a fact. Pain happens. It doesn’t own you. The point is, finally, that you’ve stopped letting fear steal the future from you in tiny, obedient bites.

There’s one night—the kind of night New York does best, fog rolling off the river like a secret coming home—when you’re both on the roof because the elevator decided to sulk and the stairs smell like Tony’s latest experiment. You sit with your back against the lip of the roof, knees up, sweatshirts zipped, mugs cradled. The city hums below like an animal settling its bones. Bucky slides down the wall until his shoulder is pressed to yours, metal warm through the cotton.

“You know the worst one?” he asks after a while, like you were already mid-conversation in some parallel life.

“The worst… scar?” you ask. You can feel him smile into his mug.

“Pain.” He tips his head against yours. “The one I hated the most.”

You go quiet the way you do when someone hands you a small, important box. He doesn’t make you guess. He never makes you guess when it matters.

“It was when I realized I was hurting someone else,” he says, soft like a confession into church dust. “Not just in the field. Not—” He swallows. You put your hand over his knee, grounding. He draws a shaky breath. “Sometimes it hit like an echo. Not mine. Quieter. I didn’t know what to call it, and I sure as hell couldn’t tell anyone. But it made me… careful, I guess. More careful than the job wanted me to be. If I could take the hit instead of giving it, I did. If I could remove a fight from a room with my body, I tried.” He huffs out a breath. “Sam says that’s why I’m still alive. Stubborn kindness.”

You blink hard against the sting in your eyes. “You did that for me,” you whisper, and it feels too big and too small at once.

“I didn’t know it was you,” he admits. “But yeah. For you. For whoever you were. I wanted—God, this is sappy—to build a world where you didn’t have to carry quite so much of me. Even if I didn’t get to see it.”

You want to say a lot of things. You choose one. “You do.”

He turns his head to look at you, and the roof becomes a quieter place. “I do,” he says, and then he laughs, soft and disbelieving. “I do.”

You don’t bring up the chair often. When you do, it’s not to pull pain up like a bucket from a well and splash yourselves with it. It’s to set the bucket down between you and say, “This is heavy. Let’s carry it together.” Sometimes he tells a story about something small—how the edges of the metal bit into his palm, how he learned the songs of the machine and where he could hide his mind between notes. Sometimes you tell a story about the day you learned to count breaths. You compare scars. You don’t rank them. You decide the only metric that matters is “we are still here.”

He touches your arm one evening and says, “There,” and you look down and see what he means: a faint pale crescent near your deltoid, one you didn’t get yourself, one you have touched absentmindedly for years. You’ve never loved your body more than in that moment, marked with your shared history like a secret tattoo.

“Matching,” you say, smiling. “I like the symmetry.”

He grins, and his grin is a revelation every time. “I like that I can kiss it,” he says, and does, and the spark you feel is not pain. It’s recognition wearing joy like sunlight.

People ask, later, if it’s hard to love someone whose pain is also yours. You tell them—when you answer at all—that love was never the problem. Love was the reason. You were careful for him, and then he was careful for you, and then you were brave together, and that was the bridge you walked across into a life that had room for both the hurt and the healing.

You don’t keep the notebook anymore. Or rather, you keep it, but you start a new one. The first page isn’t a date and a list of symptoms; it’s a grocery list that reads like a poem—tomatoes, basil, the good olive oil, bread, ice cream, patience—and beneath it, in the slanted hand you get when you’re shy, you write, “Tell Bucky the firefly story.” He snorts when you do, because he pretends to mind being teased. Then he kisses you until you can’t see the page.

There are still nights where pain rolls in without warning and you ride it out together, your breath syncing, his hands anchoring, your voice in his ear counting him through it the way you counted yourself through it for years. There are mornings when he comes back from a run with a split lip because New York sidewalks don’t care how many medals you buried. You clean it; he kisses your fingers; you bring him an ice pack for his pride. There are days so quiet you forget to be grateful and then remember and sit down on the floor just to feel it properly. There are thunderstorms. There is laughter so sudden it hurts. There is hurting that softens because you name it and hold it like a sparrow.

And there is this: a pair of matching scars with a story only you know. Not because you keep it secret out of shame, but because stories belong most to the people who lived them. If anyone asks, you can say what Clint says when he’s feeling dramatic and wants to pretend he’s not: “It’s complicated.” If anyone listens harder, you can say what Dr. Cho would: “It’s healing.” If anyone pushes, you can shrug and say, “It’s us.”

Sunshine and storm. Grumpy and gentle. Careful and brave. Two people who met in a room that smelled like antiseptic and coffee and chose, over and over, not to make each other smaller.

The world will write its own versions of you—mission reports, gossip columns, memes. Let them. Your version is the one that matters: you, in the medbay, saying “Eat,” and him, hours later, coming back with a sandwich he cut in half, placing one on a napkin in front of you like an offering. You, on the roof, mugs warming your hands, telling him about the day you decided to become a healer for a man whose name you didn’t know. Him, sprawled on his back beside you on a patch of warm concrete, pointing out constellations he remembers from a childhood spent on a different shore. You, stubbed toe and all, laughing. Him, kissing the crescent on your arm before a mission like it’s a compass.

If love is a language, you are fluent. If healing is a map, you’ve drawn a new one together, all the old scars turned into landmarks, the routes between them marked with the most unglamorous and holy word you own: “home.”

And if pain still comes—because it will, because life does not stop being life just because it learned your names

Literally finished reading this and without a second thought said “that was beautiful” out loud in the middle of the break room.

Just needed you to know that your writing stunned me 🫣
