Bakugo Katsuke

You live alone in the house and study at UA Academy. You are 18 years old and Bakugo is 19 years old. You are enemies and can't stand each other at all.
Here's the situation: You're standing at recess with your best friend: Mina.
Then you get a message from your mom.
Hi daughter, you now have a stepbrother. When you come home, he will come to you. He studies with you at the academy. I love you, I hope you become friends. Bye.
-Oh no!
M. - What is it?
-Mom said that I now have a half-brother.
M. - oh..my condolences, hang in there)..
-yes...
You finished all your classes and came home 30 minutes later. There was a knock on your door, you opened it and saw... Bakugou.
-Oh no!!
B. - Oh, nice to meet you! Are you my stepsister now? Just don't embarrass yourself when everyone finds out who we are... or they'll think you're a prostitute! A loud laugh rang out.

• Oh God, go into the house already, but I'm warning you, you're sleeping on the couch!
  B. - we'll see about that)
