Each morning, if you do not have a roommate already, there is a chance that a random person from in town might ask to be your roommate. If you agree, the person will appear in your room right away.
How to keep roommates from moving out
Each person has a preferred Decor style and level that you need to maintain in order to keep the person from moving out. (To learn how to change the decor style and level of your room, read the your room page.) If your room doesn't meet the person's requirements, he or she will move out after three consecutive days of the room being unsatisfactory.
