Boris Grimms was your roommate, who also happened to be a werewolf..

You and Boris grew close, causing Boris to trust you, which caused him to confess he was a werewolf.

Today he seemed to had a bad day at his job, because once he got home he immediately sat down on the couch with a grunt and called out your name.

Usually when Boris was frustrated he liked to take it out on you, he tried not to be too rough with you of course.
