Intro
Kirishima had always been affectionate with you. That wasn't exactly a secret.
What was a secret was how badly he wanted you.
Not in some careless, pushy way. Never that. Kirishima adored you far too much for that. He was patient, respectful, and almost painfully attentive.
But lately?
He was struggling.
You were curled up beside him on the couch, wearing one of his shirts because you'd complained that you were cold. The shirt practically swallowed you.
Kirishima stared.
Then immediately looked away.
“...You're killin' me, sweetheart.”
You blinked up at him.
“What?”
“Nothin'.”
His ears were red.
You smiled shyly and shifted closer.
That was a mistake.
Your shoulder pressed against his chest, your head settling beneath his chin. Kirishima went completely still.
He was already massive compared to you. Sitting beside him made the contrast ridiculous. His thighs were practically twice the size of yours, his arm could wrap around your waist with ease, and his shoulders seemed to take up half the couch.
And somehow, this absolute mountain of muscle was currently sitting there like a nervous teenager because his favorite girl was cuddling him.
“You're tense,” you murmured.
“Yeah.”
“Why?”
He laughed awkwardly.
“Because you're cute.”
You hid your face against him.
“Eijiro…”
“What? It's true.”
His voice dropped slightly.
“You're really cute.”
Your cheeks warmed.
He noticed immediately.
Of course he did.
His hand settled carefully against your waist, waiting until you relaxed before pulling you a little closer.
“Comfortable?”
You nodded.
“Mhm.”
“Good.”
His thumb slowly brushed against your side.
The touch was innocent.
Mostly.
But the way he looked at you certainly wasn't.
His eyes lingered on your face, then dropped briefly before snapping back upward.
He cleared his throat.
“Sorry.”
“For what?”
“Lookin' at you.”
You laughed softly.
“Why are you apologizing?”
“Because I'm trying really hard to be a gentleman right now.”
That made you laugh even harder.
Kirishima groaned, dropping his forehead against your shoulder.
“Don't laugh! I'm serious!”
“You're so cute.”
He lifted his head.
“I'm cute?”
You nodded.
“You are.”
He stared at you for a second before smiling.
“Sweetheart, I'm built like a refrigerator.”
You giggled.
“A very handsome refrigerator.”
His entire face went red.
“Okay, that's worse.”
You leaned closer, teasingly.
“Why?”
“Because now I wanna kiss you.”
Silence.
Kirishima's expression changed immediately.
He hadn't meant to say that.
“Oh.”
He swallowed.
“Sorry. That slipped out.”
But you didn't move away.
Instead, you looked up at him with that same shy little smile.
“Would that be so bad?”
Kirishima stared.
For perhaps the first time in his life, the enormous, fearless hero-in-training looked genuinely speechless.
Then he smiled—slow, warm, almost disbelieving.
“No, baby.”
His hand gently tightened around your waist.
