You’ve known Mei since your second year of high school. She was the kind of girl who always knew how to get attention—loud laugh, glossy lips, a knack for slipping into the center of every photo. You were quieter, the grounding force to her drama. Somehow, that balance worked. She pulled you into parties you never would’ve gone to, and you helped her pass tests she barely studied for.
Over the years, Mei became more of a constant than a choice. You drifted into adulthood together, still calling each other best friends because that’s what you’d always been, even if sometimes the title felt heavy.
Mei loved beautiful things—beautiful clothes, beautiful places, beautiful people. And when she managed to snag the attention of Dynamight, Japan’s #5 pro hero, she treated it like her crown jewel. The victory she never let anyone forget. To her, dating Bakugou Katsuki was the achievement. Not because she loved him—you weren’t sure she was capable of loving anyone but herself—but because of what came with him: the cameras, the money, the envy. She flaunted him like a designer bag, showing him off at every opportunity. And you… played along. Because that’s what best friends did.
Even when she whispered in your ear about how “hard” he was to date. About his temper, his intensity, how demanding he could be….they had only been dating for 6-ish months but you always nodded, comforted, agreed when she complained.
Tonight the bar is crowded, warm with chatter and clinking glasses. Lights glitter off sequined dresses, laughter carries over the music, and Mei has positioned herself dead center at the counter, nursing a cocktail like it’s another microphone for her ego. She dragged you out tonight to ‘have fun’ and ‘get some dick’ but you wanted neither— And here you are sitting at the bar in your going out dress you only whip out from time to time listening to Mei complain…again.
“—and honestly? Dating a top pro hero is basically like winning the lottery. I don’t even have to love him, everyone else does it for me.” she says with a dramatic roll of her eyes, swiping her glossy hair over one shoulder. “He has the worst temper ever but it’s worth it I guess. We’ll probably get married soon. He’s sooo loaded, you wouldn’t believe the sport car he just bought.”
You swirl your drink around pausing for a few moments after her rant. “Then why stay if he’s so bad to date?”
Mei looks at you like you’re crazy before she starts laughing loud enough for nearby people to hear and glance over. “Are you fucking kidding me y/n? He’s Dynamight. Japan’s #5. The money, the attention, the free press—it’s like dating a brand. Plus…” she leans closer, smirking, “…the sex is good—so it’s enough to make it all tolerable. He is pretty rough in bed. Not exactly boyfriend material, but damn if it doesn’t scratch an itch.”
You stiffen, trying not to show the twist in your chest “…Right.”
Mei takes another sip from her glass, “Honestly, he should be grateful. I make him look good. I’m the one who knows how to smile for cameras. Without me, he’s just some angry guy who blows things up.”
You swirl your drink once more before taking another sip and forcing a polite hum of agreement. Mei doesn’t notice the way your smile falters—she never does. She just keeps going— you’ve learned the more she drink the bigger her ego gets. She continues to pile on details like she’s performing for an audience: the PR shoots, the designer gifts, the exclusive dinners where she gets photographed by paparazzi. But your attention drifts…across the room, Katsuki Bakugou leans against the far wall, talking with one of his hero buddies that agreed to go out to drink with him—You think it was an excuse to not be around Mei the whole night...His plan clearly worked. His posture is stiff, shoulders taut even in the middle of conversation. He doesn’t laugh at something kirishima says—he never does—but his lips twitch just slightly, like he almost could.
You really shouldn’t stare. Then he looks at you. It’s nothing—barely a second. His gaze cuts through the crowd, sharp and unmissable, catching you mid-sip. Your breath snags. His expression doesn’t change, but his eyes linger just long enough to feel like a burn. Then he looks away, tossing something curt to kirishima before taking a slow pull of his drink.
You force another hum acting like you’re listening as Mei word vomits, but your mind is elsewhere, your pulse betraying you. Because no matter how much Mei brags, you can’t stop replaying the weight of his gaze, the unspoken spark that flared in that single, stolen second.
Few hours later and a couple of more cocktails— Mei is giggling too loud, slurring half her words as you sling her arm over your shoulders. “God—sh’s’cute, right? My boyfriend… #5, baby. M’gonna marry ‘im, just you wait.” Her perfume is overwhelming, her heels dragging uselessly against the sidewalk.
You’re struggling to keep her upright when a low voice cuts through the night. “Tch. She’s a fuckin’ mess.” You glance up, heart skipping. Katsuki Bakugou stands just outside the bar’s entrance, hands shoved in his pockets, expression a mixture of annoyance and inevitability. His shirt sleeves are rolled to his elbows, collar slightly undone—like he’d tried to leave earlier but hadn’t quite made it.
“I’ve got her don’t worry,” you murmur quickly, though your knees are already buckling under Mei’s dead weight.
“Yeah, I can fuckin’ see that.” He strides over, pulling her from your hold with frustrating ease. Mei squeaks and melts against his chest, mumbling, “Katsukiiii~” before promptly dozing off.
“My god does she not know her own limits?,” he mutters, adjusting her so she doesn’t slip. “C’mon. My car’s around the corner.”
You blink. “Wait—you’re driving us? You don’t have to we can just take the bus —I thought you’d maybe want to stay here longer”
“Got a damn meeting at seven. Was gonna leave anyway— Plus what kind of boyfriend am I to leave her” His tone is sharp, but his jaw ticks, like he’s annoyed. “…Let’s just get her home before she pukes.”
His car is exactly what Mei bragged about—a sleek, black sports car that hums low and powerful as he starts it up. You slide into the passenger seat, Mei sprawled across the back like a ragdoll, mumbling nonsense into her clutch.
The ride starts in silence. Streetlights flash across Bakugou’s sharp profile, his hand loose on the wheel. You try not to notice the veins in his forearm, or how the car smells faintly like smoke and cedar.
Finally, he snorts. “All I saw her do was talk tonight and you sit there nodding your head—She never shuts the hell up, does she?”
You laugh before you can stop yourself, nerves spilling out. “You have no idea. I hear every detail.”
He glances at you, quick but sharp, like he’s trying to read something behind your words. You panic, covering it with humor: “At least she brags about the car accurately. It’s… nice.”
His mouth quirks, just barely. “Damn right it is.”
It shouldn’t be funny, but it is. The tension softens, and suddenly you’re both laughing quietly—stifled, almost conspiratorial. Mei snores from the back seat, completely oblivious. And for one fleeting moment, the car feels too small. Too intimate. Like if you reached out and touched his arm, he wouldn’t stop you. But you don’t. You just sit there, heart pounding, pretending it’s nothing.
By the time you reach the shared apartment, Mei is dead weight. You struggle to keep her upright and basically dragging her out the car, but Bakugou is already out of the car, grumbling as he circles around and scoops her into his arms like she weighs nothing.
“Got her,” he mutters, nudging the door open with his boot. You hurry ahead to unlock the apartment, pushing the door wide as he strides in, his shoulders filling the frame.
It feels strange—wrong, even—seeing him here. Katsuki Bakugou, stomping through your shared living room, carrying your best friend like she’s fragile porcelain when you know he could take down anything and everything in his way with ease.
He sets her down on her bed gently, tugging off her heels with a grumble when they nearly slide off anyway. She mumbles something unintelligible, face smashed into the pillow, already gone.
Bakugou straightens, rolling his shoulders. “She’s out cold.”
You stand in the doorway, watching her for a beat before sighing. “Thanks… I probably would’ve dropped her halfway up the stairs.”
He smirks faintly. “Yeah, no shit you’re weak.”
But there’s no bite in it. Just weary amusement. For a second, the two of you just stand there, Mei’s soft snores filling the room. Finally, he jerks his chin toward the hall. “Got whiskey in that kitchen?” You linger a second at Mei’s door, watching her sink deeper into the mattress, then glance back at Bakugou. He’s still standing there, broad shoulders filling the space, hands shoved into his pockets like he’s not sure whether to leave or stay.
“Uh… actually, we do,” you whisper, stepping towards the kitchen. “Why?”
He follows, slow, heavy footsteps against the wood floor. “Helps me sleep,” he mutters, voice low, gravelly with something almost tired. “Got that early meeting. If I go home wired, I’ll be up all fuckin’ night with my mind racing.”
You reach the fridge, grabbing the half-full bottle, setting two glasses down. “Guess it’s your lucky night, then,” you say, pouring him a drink. He takes the glass from your hand, fingers brushing yours in a spark you try to ignore. He downs half of it in one swallow, jaw flexing as he swirls the rest absently. His eyes stay on you as you fill your glass with cold water.
You cut the silent tension, “You think too much?” you tease lightly, a brow raised.
He smirks without humor. “Tch. All the fuckin’ time. Meetings. Patrol schedules. Training. PR crap. Always somethin’.” He downs a sip, amber liquid catching in the low kitchen light. “Sleep’s the only time I don’t gotta think.”
You lean against the counter opposite him, cradling your glass of water. “Sounds…lonely—stressful.”
His eyes flick up at that, sharp and searching, like you’ve said something you weren’t supposed to.
“You don’t get used to it?” you press, voice softer now. “The schedule. The pressure. The whole… world watching you?”
Bakugou clicks his tongue, staring into his drink. “No…You don’t get used to it. You just get better at pretendin’ you don’t give a shit.”
The honesty hits heavier than you expect. This isn’t the bragging Mei spills every night—he’s rich, he’s famous, he’s mine. This felt raw.
“I guess it’s easier when you’ve got someone at home,” you say carefully, not sure why the words even leave you. He snorts, setting his glass down. “Yeah, right. Someone who doesn’t give a damn unless the cameras are out? Real comforting.” His mouth twists, bitter. “She likes Dynamight. Not me.”
The words hang between you. They’re heavier than whiskey, heavier than Mei’s snores drifting down the hall.
You swallow, nerves prickling. “Then why stay?”
He looks at you then, really looks, like he could peel the answer straight out of you. His jaw flexes. “PR says it looks good. ‘Fan-favorite couple,’” he mutters, mockingly, air quoting. “She plays the part, so they eat it up. Less work for me she’s been getting my rates up the last few months.”
You hesitate, then whisper, “But you don’t like her.”
He leans closer across the counter, red eyes locked on yours. “What the fuck do you think?”
Your pulse skitters, heart pounding in your throat. The air is thick, dangerous, and you break it with the only thing you can think to do—you turn to the sink, filling your glass again. You should be cussing him out for talking about her like that. This is your best friend you should be defending her. You turn back around but your nerves betray you, and the cup slips from your hand—water spills everywhere.
“Shit!” you hiss, grabbing for a towel. But Bakugou’s already moving. He crouches beside you, his hand covering yours as he presses the cloth into the puddle. His heat crowds you, whiskey and smoke in the air, his voice low by your ear.
“Y’know what I think?” His head tilts, lips so close you can feel the brush of his breath. “I think you’ve been pretendin’ just as much as me.”
Your eyes snap to his, and the tension breaks—he kisses you, rough, hard, claiming, like he’s been holding it back for months.
The kiss is explosive, his mouth crashing against yours like a storm he’s been holding back. He tastes like whiskey and heat, all sharp edges and hunger, and when you gasp, he groans into you like he’s starving.
“Fuck…” he mutters against your lips, his hands already gripping your waist, tugging you flush against his chest. “Been wantin’ this… didn’t even realize how bad.”
Your mind spins, Mei sleeping just down the hall, but the thought is crushed when he lifts you—effortlessly—and sets you down on the cool kitchen counter. Your knees part for him instinctively, and Bakugou slides between them, pressing hard against your core. You whimper, hands fisting his shirt. “Katsuki—we can’t—”
“Shut up,” he growls, but there’s no cruelty in it—just desperation. His palm cups your jaw, his forehead pressing to yours. “Don’t fuckin’ say we can’t. You feel that? Tell me you don’t want it.”
Your hips rock against his, betraying you. His smirk is wicked, breath hot as he mutters, “Knew it.”
When his hand slips beneath your dress, dragging your panties aside, you bite your lip so hard you nearly draw blood. He strokes you with rough, calloused fingers, and your soft gasp nearly echoes.
Bakugou freezes, glaring at you with wild eyes. “Shhh.” His other hand covers your mouth, heavy and firm. “You wanna wake her up, princess? You wanna let Mei know how good I’m makin’ you feel?”You shake your head, eyes wide, moaning into his palm as he sinks two fingers inside you, curling just right. He watches your expression darken with need, his grin sharp.
“Figures. She doesn’t even fuckin’ listen when I tell her what I like. Too busy complainin’.” His lips drag along your throat, biting hard enough to mark. “But you… you’re fuckin’ dripping for me.”
The words alone make you clench around him, and he notices. His chuckle is pure filth. “Ohhh, you like that? You like me talkin’ about how much better you are than her?”
You whimper a “yes,” and that’s all it takes—he yanks his belt open, shoving his pants low enough to free himself. He’s big, hot, thick, and when he pushes into you, you nearly cry out.
Bakugou slaps his hand over your mouth again, growling into your ear, “Quiet. Don’t you fuckin’ ruin this.”
The stretch has your eyes rolling back, your nails digging into his shoulders. He buries himself to the hilt, holding there for a moment before pulling out almost completely, then slamming back in. The counter shakes with each thrust, your body arching into him helplessly.
“Fuck, you take me so good,” he groans, voice rough and raw. His lips brush your ear. “She can’t handle me like this. Always tellin’ me I’m too rough, too much. But you—shit—you’re made for it.”
Tears prick at your eyes from the overwhelming pressure, but you’re nodding, gasping into his hand, your body answering him with every thrust.His rhythm turns brutal, relentless, the counter creaking under you both. “Look at you. Keepin’ quiet for me. My good fuckin’ girl.”
Your release builds fast, impossible to fight. He feels it, smirking as his pace grows savage. “That’s it. Come on. Cream all over my cock while your best friend’s passed the fuck out in the next room. Gonna let her keep braggin’ about what’s mine?”
Your orgasm rips through you, white-hot, muffled screams spilling against his palm. The sensation drags him with you, his thrusts stuttering as he buries himself deep, groaning your name like a curse. When it’s over, the kitchen falls silent but for your panting. He finally pulls his hand from your mouth, dragging his thumb across your wet lips. His grin is wicked, hungry still.
“Guess we ain’t pretendin’ anymore, huh?”
The kitchen still smells like whiskey and sex, your legs trembling as you adjust your dress and try to catch your breath. Bakugou is already buckling his belt, wiping his hands casually on a paper towel like he didn’t just fuck you against the counter while your best friend slept a room away. You can’t even look at him. Shame burns under your skin, and the second you grab a rag to wipe at the water spill, he snatches it from your hand.
“Oi,” he mutters, voice still rough. “Don’t start that shit.”
You blink at him, startled. “What?”
“That look.” He wipes the counter lazily, jaw tight. “Don’t fuckin’ look like you regret it. ’Cause you don’t.” His eyes flick up to you, sharp and knowing. Your stomach twists, the memory making heat pool low in your belly all over again. You open your mouth, but nothing comes out. Bakugou tosses the rag in the sink, stepping close enough that his heat crowds you again. His hand snags your chin, tilting your face up so you can’t avoid him. His eyes are molten, dangerous, and so goddamn sure of himself.
“This isn’t over,” he growls, low and deliberate. “Not by a fuckin’ long shot. Don’t run from me, baby—you wanted this just as bad.” Your lips part, breath shaky, but before you can reply, he lets you go. He grabs his jacket off the back of a chair, throws it over his shoulder, and stalks toward the door without another word. You can’t deny it cause the second they started dating you wondered what it was like to get fucked by a strong hero like him. The click of the door shutting echoes in the silence. You’re left standing in the dim kitchen, heart pounding in your throat, his scent clinging to your skin.
After a long moment, you force yourself to move. Cleaning up the last of the water, putting the glasses in the sink, locking the door. Everything feels mechanical, like you’re trying to hold the pieces of yourself together. You pad down the hall toward your room, the apartment quiet but for your own unsteady breathing. As you pass Mei’s door, you pause. It’s cracked open, soft snores spilling out. You peek inside. She’s sprawled across the bed, one arm dangling, makeup smudged from the night out. Peaceful, completely unaware. Guilt rips through you like a knife. Your hand curls tight on the doorframe. You whisper to yourself, barely audible—
“…what the fuck did I just do?” But there’s no answer. Just Mei’s steady breathing, and the echo of Bakugou’s voice in your head. This isn’t over. You close her door gently, as if that might keep the secret locked inside with her, and slip into your own room—knowing you’ll never sleep the same again.
