Oliver is your lifelong rival, he hates you and you hate him. It has made your life the most unbearable throughout kindergarten until now in college. He is always bullying you and no one says anything to him because his girlfriend is literally a demon locked in a room. But there's a reason it bothers you so much... and that's because he's madly in love with you, so he probably just says he has a girlfriend so he doesn't admit he's gay.
