Only You Can Call Me That
Pairing: Bucky Barnes x reader
----------
Bucky Barnes didn’t mind most things.
He didn’t mind silence. Didn’t mind long nights. Didn’t mind sitting in the corner of a crowded room with his back to the wall and his thoughts wound tight around his ribs.
He didn’t even mind the teasing that came from Sam—who never once hesitated to call him a grumpy old man or throw a pillow at him during movie nights.
But the one thing Bucky did mind—the one rule that even Steve used to respect, that even Tony Stark knew not to cross?
Don’t call him Buck.
Not because it was an awful name. Not because he didn’t hear it a million times in Brooklyn growing up, barked from front porches or whispered across rooftops during stolen moments with Steve. No—he hated it because it lingered.
Because when someone called him Buck, he could hear Steve’s voice in it.
Not just Steve’s. But Steve’s most of all.
Bright. Loyal. Laughing. Sometimes broken. Always familiar.
And now, always gone.
That nickname was tethered to a thousand memories Bucky hadn’t asked for. It caught on the edges of his nightmares, clawed its way through the dust of the past, and made his chest hurt in ways he didn’t have words for.
So, the rule stood: No one calls me Buck.
Not in the field. Not during training. Not even as a joke.
Sam Wilson learned the hard way. One time, in a moment of poor judgment and high altitude, Sam called out, “Let’s go, Buckaroo!”
Bucky didn’t hesitate. Threw him out of the Quinjet with a deadpan look and zero remorse. (Sam had a parachute. Bucky wasn’t completely heartless.)
“Don’t call me that,” he’d said, calm as ever.
Sam still brought it up over beers, rubbing his shoulder like the betrayal had left a bruise. “You nearly killed me.”
“You landed in a lake.”
“That water was cold!”
“Good,” Bucky said, and didn’t explain any further.
Then you came along.
You, with your soft voice and even softer heart. You didn’t charge into the compound like most new recruits or agents. You didn’t demand attention. You didn’t try too hard to impress anyone. You were just… kind.
Civilian liaison. Logistics specialist. Consultant. No one was quite sure what your official title was. All they knew was that you were helpful, warm, patient—and somehow untouched by the usual hardened edge that clung to most people in this line of work.
You brought coffee to overworked interns. You remembered birthdays and dietary restrictions. You complimented Natasha’s combat boots and made Peter blush when you called him “genius boy.”
And when it came to Bucky… you were gentle.
Not cautious. Not afraid. Just… gentle.
You smiled at him. Spoke to him like he was anyone else. You didn’t prod or hover or flinch when his metal fingers twitched. You didn’t look at him like he was a weapon.
You looked at him like he was human.
He didn’t know what to do with that.
The first time it happened, you were both in the kitchen.
It was early—just after sunrise. You were standing on tiptoe trying to reach a jar of tea on the top shelf, fingers brushing the lid with no success. Bucky watched for a minute from the doorway, arms folded.
You hadn’t noticed him yet. Your sweater was too big, your socks mismatched, and there was a pencil holding your hair up. You looked like you belonged in a rom-com, not in a building full of elite operatives.
He stepped forward.
“Need a hand?”
You startled, blinking at him. Then smiled.
“Sergeant Barnes,” you said, breathless from the stretch. “Thank you.”
He reached up and snagged the jar with ease, setting it on the counter beside you. You looked up at him with those bright, open eyes and said—
“Thanks, Buck.”
He froze.
Something stuttered in his chest. The air thinned. The name hit him like a brick to the spine—but only for a second.
Because the way you said it was different.
It wasn’t clipped or casual or tied to some memory that made him ache. It was light. Easy. A soft curl of sound, sweetened by your voice.
“Buck,” you repeated with a teasing smile. “Hope that’s okay. ‘Bucky’ sounds like something a kid calls their teddy bear.”
He opened his mouth to correct you. To tell you that, actually, no, he didn’t let people call him that.
But instead, he said—
“…Yeah. That’s fine.”
You called him Buck again later that afternoon.
“Hey, Buck, do you know where Sam keeps the good pens?”
And the day after that.
“Buck, I saved you the last blueberry muffin.”
And again. And again.
Every time, he flinched internally—but not in the way he used to. Not in pain. Not in grief. Just… in surprise.
Because every time you said it, it got a little softer. A little lighter.
It didn’t feel like a ghost anymore. It felt like you.
Sam was the first to notice.
Of course he was.
It started small—just the tilt of his head when he heard it in passing. Then came the furrowed brows. Then the full-on outrage.
“I’m sorry,” Sam said one morning over breakfast, stabbing his fork into a pancake like it had personally offended him. “Did she just call you Buck?”
Bucky shrugged.
“And you didn’t throw her off a balcony?”
“She’s not annoying.”
“I said good morning, and you sent me skydiving without consent!”
Bucky kept eating.
Sam threw his hands up. “This is bullshit.”
The more you said it, the more natural it became.
“Morning, Buck.” “You want to join us for game night, Buck?” “You always look so serious, Buck. Smile more.”
And the more Sam suffered.
At one point, he caught Bucky smiling at the sound of it.
“I’m gonna lose my mind,” Sam muttered. “You’re smitten.”
“I’m not.”
“You’re whipped.”
“I am not.”
“She called you ‘Buck’ and you blushed.”
“That’s your imagination.”
“Steve is rolling in his grave right now.”
Bucky didn’t respond to that one.
Because maybe Steve would’ve smiled. Maybe he would’ve been happy to see Bucky smile again.
It wasn’t just the name.
It was you.
You were so… good to him. And Bucky didn’t know how to handle good things.
He’d spent so long surviving—through war, through Hydra, through guilt and frozen decades—that kindness sometimes felt like a threat. Like something he didn’t deserve.
But you didn’t ask for anything. Didn’t push. You just gave.
One afternoon, you showed up at his door with a pack of ginger chews.
“I heard they help with nightmares,” you said softly. “You don’t have to take them. I just… thought of you.”
He stared at you for a long time, unsure what to say.
“Thanks, Buck,” you added as you turned to leave.
And Bucky stood there holding the candy like it was something sacred.
Weeks passed.
He found himself looking for you. Waiting for that nickname to float through the air and find him like a beacon.
He didn’t flinch anymore.
He leaned into it.
It all came to a head one particularly slow afternoon in the common room.
You were curled up on the couch, legs tucked under you, scrolling through your laptop. Bucky was beside you—not close enough to touch, but closer than he ever sat with anyone else.
You’d become his favorite kind of company: the kind that didn’t need anything from him.
The TV played a low hum of background noise. Sam walked in with a sandwich and flopped into an armchair, halfway through a rant about training drills when it happened.
You nudged Bucky gently.
“Hey, Buck, you left your coffee in the kitchen. Want me to grab it?”
Bucky didn’t even hesitate. “Nah, I’ll get it in a sec.”
Sam’s sandwich hit the floor.
“WHAT?!”
You jumped.
Bucky looked up slowly, brows raised. “What now?”
“She called you Buck.”
“…Yeah?”
“And you answered.”
“Okay?”
Sam stood dramatically. “You—you threw me out of an aircraft.”
“You were being obnoxious.”
“I said what’s up, Buck. Once!”
“You said ‘Buckaroo.’”
“Oh my God,” Sam whispered. “That’s not the point. The point is you’ve made it a whole personality trait to hate that nickname and now—now you let her say it like it’s your favorite word!”
Bucky shrugged, completely unbothered. “She says it different.”
You blinked. “I didn’t know it was off limits…”
“It is,” Sam said, pointing at Bucky. “Unless apparently you have a soft voice and smile like sunshine, and then suddenly it’s a goddamn honor badge.”
Bucky looked at you.
“It’s not off limits for you,” he said, quiet and sure. “You can call me Buck.”
Something in your chest fluttered.
Sam groaned. “You two are disgusting. I’m filing a complaint.”
Bucky leaned back with a small smile, watching you tuck your face behind your laptop to hide the growing blush on your cheeks.
Later that night, he found you on the rooftop.
The wind was cool, the stars dim against the city haze. You were wrapped in a thick sweater, sipping from a chipped mug, your feet dangling over the ledge. Not dangerously. Just comfortably.
You didn’t turn when he sat beside you.
“I didn’t mean to step on a landmine,” you said after a pause. “About the nickname.”
“You didn’t.”
“I would’ve stopped if I’d known.”
“I wouldn’t have let you start if I didn’t want to hear it.”
You turned to look at him, brow furrowed. “But it reminds you of Steve, right? That’s why…”
He nodded slowly.
“Yeah. For a long time, it did. Too much. Too loud.”
“And now?”
Bucky swallowed hard, then looked at you—really looked at you.
“Now it reminds me of you.”
Silence.
Then, softly:
“Is that okay?” he asked.
You smiled. “It’s perfect, Buck.”
His eyes softened.
And for the first time in a long time, the name didn’t hurt.
It healed.
