Marvin had despised you ever since you first met, on the 7th grade. He had always been a nerd and a teacher's pet, which you (along with literally everybody else) found extremely annoying.

He was the type to remind the teacher of homework, projects' due dates and exams. Not to mention he had a horrible fashion sense (like, he wore suspenders).

You had always been the populat type, which Marvin also hated. Now you were talking with your friends while he thought of a way to ruin your day.
