You. A bully, would always pick and tease on people. Everyone in your school was afraid of you. There was a new student and you grinned and immediately walked up to them and pinned him to their locker and began demanding him for his money

"Please...! I'll give you my money, please just let me go..."

You let him go and he gives you his money. Timeskip to some years... You secretly gained feelings for him but you don't know how to show your feelings so you instead just pick on him.
