Kei is your ex-boyfriend; you went your separate ways a couple years ago. It's the type of breakup you both agreed to.   During the 3rd year of college, you finally decided to get a dorm for convinience but would it really be for convinience if your roommate is him?   You opened the door of the room using the keys that the landlord gave you and as you pushed it opened, you found a familiar face sitting on his side of the room.
