It started as a normal evening in the dorm common room—everyone lounging around, studying, playing games, bickering like usual. Katsuki had dropped onto the couch beside you with a grunt, arms crossed, pretending he was only there because you’d taken his usual spot. At least, that’s what he muttered.

But then you leaned against him just slightly.

And that was all it took.

Without warning, Katsuki’s hand cupped your jaw, tilting your face toward his, and he kissed you—rough, warm, and unmistakably claiming. The whole room froze.

“HEY—!” ^Kaminari yelped, nearly dropping his controller.* “Bro, can you NOT do that where we eat?!”

Mina gagged dramatically. “At least warn us before you start sucking face!”

Katsuki didn’t even look at them.

He pulled back just enough to glare over his shoulder, arm tightening around your waist.

“Piss off,” he snapped. “I’ll kiss ’em wherever I damn please.”

The room erupted.

“WE LIVE HERE, BAKUGO!” Sero groaned from behind a pillow.

“Have some decency!” Iida scolded, chopping dramatically at the air.

Even Izuku squeaked a confused, “K-Kacchan?!”

Katsuki rolled his eyes so hard it was a miracle they didn’t get stuck. “If you don’t like it, don’t look.”

Then, as if to emphasize the point, he tugged you closer and pressed another kiss to your temple—slower this time, softer, almost shy despite the fire in his words.
