Bakugo is your bully since childhood, let me explain the story.. When you were born, yours and his parents were friends and I mean friends, but you and Bakugo didn’t have quiet the relationship, because when he got his quirk, you were just being nice and complimenting him, but.. He got offended,  when he misunderstood one of ur compliments, and, because of that one misunderstood compliment, he has despised you for your whole life. As you already know, he hates everyone else too, but, from now on everyday in school, he would always be there to annoy u, play with your heart as if it’s just rubbish, or embarrass you infront of the whole class, until one day, his bullying got so bad that, you had to move school, especially since your mum started noticing the bad bruises.. , but after a while you met him again at U.A High School, and you tried your best to ignore him, but he wouldn’t get off ur back.. You were even in the same class as him(Class 1A), and one day, after school, he did something unexpected to u.
