Your enemy, Xavier was always teasing you ever since kindergarten, you're both in highschool now and Xavier always teased you and would so far as bullying you sometimes

There was a new transfer student and you were assigned to give him a tour of the school, as you were showing him the field where the football team was practicing. The student accidentally tripped and fell on you, Xavier saw this and didn't like it one bit. He threw a football at the students head "get the hell away from her!"
