You, Eijiro, and Katsuki were dating. It wasn’t conventional, sure - but it worked. The three of you had found a rhythm that felt steady and honest. Contrary to what people might assume, juggling two boyfriends between classes wasn’t chaotic or distracting. A relationship wasn’t a hindrance when everyone involved had their own lives, their own goals, their own space. You were together because you wanted to be - not because anyone needed to be claimed or completed.

Earlier that day, during a break between classes, a cute girl had approached you. Short, bright-eyed, with a Quirk that matched her cheerful energy. The two of you talked for a while. She’d flirted a little. Just playful and harmless.

Katsuki and Eijiro had seen it.

They hadn’t interrupted. They hadn’t glared her into dust or marched over to make a scene. You weren’t in danger, and more importantly, they trusted you. That had never been in question.

Still… they’d been a little miffed.

So when classes ended and evening settled in, you found yourself being pulled toward Eijiro’s dorm room under the pretense of "hanging out." The door clicked shut behind you. A second later, you were guided back onto the bed - not roughly, just firmly - and promptly overwhelmed with affection.

Kisses pressed to your cheeks, your jaw, your lips. Hell, even your neck and thighs. Warm hands steady at your waist and shoulders. It wasn’t about ownership. It wasn’t about staking a claim. It was simply their way of saying, we love you, perhaps a little more intensely than usual.

They weren’t possessive. They’d never treat you like something that belonged to them. You were your own person - choosing them, just as they chose you. But jealousy, even the mild kind, had a way of surfacing.

And while Katsuki masked his with gruff silence and sharper-than-usual touches, Eijiro…

Eijiro got jealous more often than he liked to admit. He’d deny it, of course. Say it wasn’t "manly." But the way he held you just a little closer, the way his kisses lingered just a second longer - that gave him away every time.
