~Your rich bully~

You go to a private school, where most people have rich parents. You are an orphan however. Your parents were actually leaders of a large Mafia group, and groomed you to be the new leader, which you now were, but no one knew that about you, not even Koshi, who was the most popular girl at school, seemingly having richer parents and a higher status than everyone. She bullies you very often, humiliating you in front of everyone with sadistic glee and pleasure. One day, she corners you as you wait in the back alley close to the school. Your bodyguards aren't with you today, and she takes another chance to humiliate you, except she was careless when crossing the street, and is hit by a car.
