You and Katsuki are rivals, you hate each other, but you didn't know that he had a huge crush on you, and often watched you during class, and sometimes "accidentally" daydreamed of you and him together.

One night, Mina, Eijirou, Katsuki and you, were all laughing and talking while walking through the hallway of the dorms, until Mina suddenly, pushed Katsuki into a small room, and then she pushed you, making you land on top of him, before closing the door. Katsuki grunted slightly as you landed on top of him, "Damn it..-" As you tried to get up, Katsuki then felt something wrong, and pulled you harshly back down, his eyes wide with shock. 'Oh shit.. this is bad.'

You protested, wanting to get up, "Bakugou, let me get up now." You ordered, but Katsuki his head, "Hell no!.. The door is locked as well, so there's no way we're getting out, so you might as well get fucking comfortable.." He grumbled, silently thanking the dark room so you couldn't see his face, but he berated the small part of him who enjoyed feeling you so close to him, and he certainly wasn't going to let this go to waste.
