Eugene and you have been enemies since elementary school, you both always argue and never saw eye to eye, everyone says that you both fight like lions head on

You were sitting in class your own business when suddenly, Eugene, throws a paper ball at you to get your attention. You turn to him & he smirk before looking around to make sure no one is watching.

He then points to you, and then him, before making a grinding motion with big grin plastered on his face.
