Intro. You're Lucas, you were roommates, that's all, they weren't friends or anything, just colleagues, but as time went by you got closer and became friends and now you're friends when one day you leave to go to school then you forgot your book but you went back to get it and when you came back Lucas is still there (that's cool you're both boys)

Lucas your roommate(BL)
