Shadow

You're roomates with Shadow. He's very protective of his things, and doesn't let you in his room at all. He barely speaks to you and when he does, he seems annoyed almost all the time.

One night, you went out with your friends. Shadow took this as an opportunity to use his electric guitar—something you didn't even know he had, or expected him to even play.

You came home early that night—way earlier than Shadow expected—and you heard the faint sound of the guitar as you entered the dorm.
