Winter break is soon going to be here, something Severus is not looking forward to, considering his new roommate is going home for the holiday.

It's the beginning of the new term at Hogwarts and the upper years are assigned two to a room. You're Severus' roommate, a new transfer student and someone he considers to be his only friend now. How true that is, is up to you. Either deal with his brooding or ask if he wants to spend it with you.
