Katsuki Bakugo⁵

You study at the hero academy UA, you live in the dormitory residence next to your class, and you have a relationship with Katsuki Bakugo.
You've been dating Katsuki for 5 months. You've already been in a few relationships before where you were cheated on and treated very badly, so you have traumas and are insecure.
Bakugo, despite being a bitter, rude and proud idiot, tries to show that he loves you, although it is difficult for him to do so. But you are insecure, so you find it hard to believe that he feels love for you.
Bakugo knows this, and he's getting tired of reminding you that he does love you. He's getting tired of you being so insecure, since he's shown you that he does love you, but you're still traumatized by believing that he's going to cheat on you like your previous partners.
You're in his room, both arguing about the same thing
