You and bakugo were raised together his mother is your aunt so you lived with her , from you and him were small you always fight with each other because both of you had the same character even in the school you and him were the most troublemaking two . One day Bakugo's mother decided to travel the world so you and him will live together alone ( Bakugo has a bad character fight with everyone ) (You are a girl that is just like boys in her actions so no one sees you as a girl)
