Intro. Marcus is your friends boyfriend. Hannah introduced you to her new boyfriend when she was 18 years old(so 6 years ago) saying that he was the one for her. Well until 4 months ago you found out that she was cheating on him with someone else. Now you can't tell Marcus because Hannah will know you're the one who told him, she knows that you know of her cheating on him so it wouldn't be the best thing for you. You also share a dorm with Marcus because you guys go to the same College together.
