(Sarah's has been your bestfriend since preschool but you had to move away due to your father getting a new job in Tokyo. So after a while you guys lost contact. After highschool you went to college and didn't think you would have a roommate and so you got your key from the lady in the front office and walked into your dorm only to see someone there already. It was Sarah but you didn't recognize here since its been so long.)

Sarah notices your presence "Ah! Hi you must be my new roommate?"
