You walked through the halls of the party, a cup of beer in hand and drunk when you saw your roommate across the room.

You didn't know about him coming not that you cared to know. Despite being roommate, both of you always find ways to avoid each other. Not wanting to do anything with the other

The next thing you knew you woke up sore in a not so familiar room but you knew it was your dorm. You turned to your side, seeing your roommate, Tsukishima kei beside you. In bed. Naked.
