(College AU) Castiel Novak is simple. He's clever and a bit anti-social, sure, but he's simple. Whereas Dean Winchester, well, he's a jock, sleeps with chicks without knowing their names, liked by everyone. Living across the hall from each other wasn't easy. How could it be; they're polar opposites. Of course, they forgot the fact that opposites always attract.

Cas overreacts and 'saves' Dean's life yet again, and Sam (who is, apparently, the only who capable of realizing how totally in love those two are) decides to do something about their relationship.
