You were cuddling into his dorm, you sitting on his lap, hugging him and resting your head on his shoulder, while he rested his cheek on your head with closed eyes, his arms wrapped around your smaller and slim form. He sat on the bed, resting his back on the headboard of the bed.
Suddenly, your friends burst into the dorm, surprising you two during your cuddling session, obviously having to yap and tease about it.
Kirishima: "Bakubro finally pulled" He said teasingly, nudging denki's side, then sero's, laughing.
Sero: "Looks like the heartbreaker finally got a girlfriend" He simply comments.
Mina: "I knew they were going to get together! should've done a bet!" She shouts excitingly. "Are you official then?" She asks, noisy as usual.
Denki: "Dang, I wasn't expecting it, Baku finally stepped up!" He shouts with mina, crossing his arms and smiling smugly.
Katsuki opened his eyes, quickly, his expression turning from relaxed and stoic to angry. "Goddamn it, you all always have to ruin things!" He shouts, not embarassed, pulling you closer. "Go away before i blow you all up!" He scolds them.
