Work Text:
The soft click of the door as it opens allows light to spill into Izuku’s darkened room, and the green-haired man smiles to himself.
“Hello, Kacchan,” he mumbles, even though his back is turned to the blond as he enters. Izuku knows it’s Kacchan — who else would it be?
The telltale warmth of a body pressed against him has Izuku giggling to himself as he swivels to face his best friend.
“S’up,” Kacchan says awkwardly, as if they’re not snuggled up in bed together. Izuku knows that the blond likes cuddling, but that he’s always self-conscious about it. Izuku also knows how to ease him.
He leans forward and presses a barely-there kiss against Kacchan’s nose, mirth dancing in his eyes as he watches his best friend flush. Affection, even if it’s platonic, makes Kacchan blush, and Izuku secretly loves it. No one else sees Kacchan blush.
“How was work today?” Izuku asks quietly, and Kacchan shuffles closer, pulling Izuku against his chest so that he can hear his best friend’s steady heartbeat.
“It fucking sucked without you,” Kacchan grumbles, muffled by Izuku’s hair, as the blonde has conveniently buried his face in Izuku’s locks. Izuku pulls back a little so that he can look up at Kacchan properly, but they’re still barely an inch apart, so close that he can feel the other’s breath against his mouth.
“I missed you too, Kacchan,” Izuku returns sincerely, leaning somehow closer still out of habit.
They’re still for a moment, staring at each other without so much as moving to blink. This happens all the time, and it’s usually Kacchan who will move away, put some distance between them, before settling in again for more cuddles.
But Kacchan doesn’t move.
It’s important that Kacchan moves, because Izuku never does. Izuku’s too weak to deny Katsuki any affection, but he doesn’t mind, because Kacchan always has a level head. Except…
“Kacchan,” Izuku breathes, lips almost brushing his best friend’s. It’s an invitation masked in a warning.
“What?” Kacchan replies, his expression lifting up into a sneaky grin half way through the word. Oh. Oh .
“Kacchan!” Izuku whines, smiling all the same. “You’re being mean!!”
Kacchan laughs, giving himself away even more, before leaning forwards to press a quick kiss against Izuku’s forehead.
“Shouldn’t get so serious, then, Deku,” he teases, lying back and wrapping an arm around Izuku, who pouts jokingly before cuddling up against Kacchan.
“Sing me a lullaby as an apology,” Izuku demands, poking his best friend’s cheek.
“Nope.”
“Please?”
“Nope.”
“Fine. I love you anyway.”
“...Ugh, you manipulative little shit,” Kacchan groans, before clearing his throat. “ Lullaby, and goodnight, go to sleep, stupid nerd, if you don’t, I’ll kill your ass, better sleep well tonight. Blah, blah, blah, I can’t sing, why aren’t you asleep yet? Go to sleep, Izuku, know that I love you, too .”
Just as Izuku feels that he might be starting to drift off, curled up against his favourite person in the world, Kacchan adds:
“But no homo, dipshit.”
Izuku sighs. He’d have thought that they were both aware by now.
Ah, well. He guesses it
could
be gayer.
