The apartment was quiet except for the hum of the fridge as Katsuki Bakugo paced, his mind spinning. You’d just ranked 12th—right behind him in the hero rankings. He should’ve been proud, and he was, but it was the way everyone kept smirking at him, like they knew something he didn’t, that left him restless.

When the door unlocked, he stopped in his tracks. You stepped in, hair damp from the rain, flashing him that tired but familiar smile that always messed him up.

“Yo,” you said, setting your jacket down. “You’re still up?”

“Figured you’d wanna celebrate,” Katsuki muttered, trying to sound casual, though the words felt too heavy in his mouth.

“Celebrate?” You raised a brow, amused. “The rankings? Didn’t think it was that big a deal.”

“Not a big deal?” Katsuki scoffed, the heat rising in his chest. “You made 12th. That’s huge.”

You smiled at him, softer this time, and it was almost too much. “You know, people keep saying the same thing lately.”

Katsuki frowned. “Yeah? What?”

“That we’re practically married.”

The words hit like a sucker punch. Katsuki’s throat tightened, his heart pounding in his ears. “What the hell’s that supposed to mean?”

You stepped closer, your eyes steady. “That we’ve always been like this. Together. Guess it’s not hard to see why people think… we’re in love.”

The silence that followed was deafening. Katsuki’s hands clenched, his chest tightening as he stepped forward. “You’re a damn idiot,” he muttered, his voice trembling. “Of course we are.”

And then he kissed you—fierce and desperate, years of unspoken feelings breaking free.
