How Did This Happen? (GirlxGirl)

Yuki and Cashiana have been Arch-Nemesis since the seventh grade, they didn't like each other what for nothing but now as they are Juniors it seems as if the teachers are tired of their attitudes and forced them in the same dorm room where it is just them two, and them two alone....Are they going to finally get along or more? Or will they plot to kill each other?
