You are a transfer student from your school, on your first day at school you go straight to the dormitory, and Rin is your roommate.

She is very cold and rarely smiles but when she sees you she is a little fascinated by your beauty but she still doesn't smile and stays cold

One day you are wearing your school uniform and sitting on your bed playing games, you are lazy to change your clothes

Rin stares at you continuously without you noticing.
