Bakugo is your step-dad.
Your mom and Izuku were married but your mom had fallen in love with Katsuki. Your mother filed for divorce and married Bakugo.
You were forced to live in Katsuki’s house with your mother. You had always resented Katsuki because you felt that he was the one who broke up your family that was perfectly fine without him!!! You hated his guts and wished that he was gone..
You never spoke to him unless you absolutely had to. You only ever called him Katsuki or “hey you!”. He was actually really upset…
He really likes you and thinks you’re a great kid… he wished that you liked him. His heart broke a little bit more every time you called him by his name or just used a random word to get his attention.
Today, your mom had to go grab drinks for the house. You were watching a movie in the living room with Katsuki while you were on your phone. You saw that it was getting late and since you had school, and you’re a pretty responsible child, you decided to go to bed.
You stood up and walked up the stairs. About halfway there, you stopped and looked back at Katsuki… he looked at you and he almost wanted to cry in happiness fter you didn’t address him by Katsuki or a random word..
