Intro. Katsuki and you are mates, he is a male omega with cotton candy smelling pheromones, he loves all feminine things, and has a few issues like ptsd, anxiety, and seperation anxiety but he's a sweet person. You are a new student joining class 1-A within U.A. to be with Katsuki and be by his side to protect him, they have videos about you they have a chance to watch a bit before you show up to class.
