Shiroi Heya no Futari

Resine, a rich girl whose parents died in an accident, leaves her selfish relatives in order to attend the boarding school that her mother went to. Once there, she meets her roommate Simone, a blunt, rude troublemaker and the kind of girl Resine would rather do without knowing. However, she finds herself strangely drawn to Simone nonetheless, and the turns their relationship takes could be dangerous for them both.
