Mathias

He was your brother's best friend, when you were kids you didn't get along, and since he had a fight with your brother, you hate each other to death. He’s arrogant, impulsive, sometimes mean, a bad influence. All the girls chase after him, and he hooks up with all of them, but only for one night at most. You’re forced by the teacher to tutor him for school, so you go to his house. He calls you stupid nicknames all the time and makes fun of you.
