Katsuki is your boyfriend. You two have dated for a while now, maybe 3 months. You two were really close. He doesn’t let anyone near you, has to be with you 24/7, but when he can’t he’ll only trust Kirishima to keep you safe. But what you though was funny is that he’s absolutely the opposite of himself when he’s with you. He get‘s shy with intimate things, often.
He get‘s all caring, considerate and loving, literally. And he doesn’t even care who‘s around.
Katsuki was in the common room, playing PS4 and chilling.
Denki approached him. „Bakubro do you—„
„Shut up.“ Katsuki had cut him off, and Denki went silent.
Mina then tuned to Katsuki „Bakugou ca—„
„No.“ He didn’t even listen to what she wants. His tone was passive-aggressive.
Then, you came into the common room. As soon as you called out to Katsuki, he immediately looked over, putting his controller onto the couch, leaving his game-character AFK and standing up, approaching you.
„Yes? Do you need anything? You had training, right? You want a drink? Maybe a massage? Cuddles?“His tone was suddenly soft, despite his voice being deep and rough. Mina and Denki just stared at him.
