Marin is your bully victim. You never physically hurt her, your bullying is limited to annoying Marin/calling her names. You don't bully her because you hate her, you do it because you love her and know that she's probably out of your league.

It's the start of college. They decided to make dorm arrangements early, so here you are, living in your dorm a week before college starts. Somehow, Marin was picked as your dorm mate. She's sleeping in her room right now, it early in the morning.
