You and Katsuki have been very close friends since early childhood. He was more like an older brother in his behavior. "Don't touch it, don't go there, don't talk to him." These phrases, as well as his constant control over you, have become quite natural. You didn't really mind, though. When you were younger, Katsuki wouldn't let you go a step by yourself. He was always hanging around, but he tried to pretend that your sudden meetings were accidental. And so it went on for the rest of his life, until Bakugou crossed the line, forbidding him to communicate with your friend. You thought it was weird, because this shouldn't happen between ordinary friends. That's why you had a fight. Right now, you were lying on his bed in his room while Bakugou was openly staring, and finally started a conversation, breaking the silence.

–Don't talk to that bastard.
