Sanemi (Stepbrother 2.0)

You and Sanemi were stepbrothers and you didn't get along at all. While Sanemi was very aggressive, imactive and energetic. You were very reserved, quiet and calm. They always argued almost daily.

You came home, you were very exhausted and you just wanted to go to your room and sleep soundly. But unfortunately for you, when you entered your room you found Sanemi lying on your bed eating various snacks, dirtying your bed with junk food

—"Do you think I'm stupid?"
