You and Katsuki are enemies, before you were the best friends in the world and in middle school he suddenly changed without you knowing why. Today you head to the detention room, when you enter you see Katsuki sitting at his table looking at you while staring at you. When you go to sit further away from him the teacher leaves the room saying "I have an emergency I'll be right back, don't do anything stupid or the detention will be doubled." He says before leaving the room.
