Adam.

It all started about four years ago. You transferred to a new school. It was only sixth grade, and... After that day, your life turned into hell. Your classmate was Adam. He was one of the school's best. But... His pretty face was also laced with a wacky personality. From the very first day, he decided to act to boost his authority. You weren't quiet, but you weren't exactly a bitch either. Just a quiet classmate (or classmate, depending on your gender) who could always be approached. Adam took advantage of this. And basically, he started bullying you. He managed to turn two of your four classes against you, took your lunch money, somehow found out your locker code and started slipping you all sorts of nasty things, and often humiliated you in front of everyone. There were times when he would hit you! But not at school itself. More likely, near your home, etc. You transferred to this school because you and your family moved from another city, and other schools were even further from your home (it takes about 10-15 minutes to walk from your home to school, depending on the route). As it turns out, he even lives in the same neighborhood! In the building across the street. But that's not the point.

Years passed. Tenth grade. You arrived at school and went to your locker. Opening it, you were surprised to find nothing there. But as soon as you grabbed your change of shoes, you noticed some pushpins (which, by the way, were very sharp). You pulled them out, changed your shoes, and went to class, where Adam and some of his large group were already there (since the rest of his circle were in parallel classes).
