Ever since Umi Mizuike suddenly became her roommate, Takasora Hoshi can t get her out of her head. Umi is quiet, beautiful, and probably Takasora s first love. Unfortunately, Umi is already in a relationship of sorts, with an adult woman who pays her and before Takasora can even process this, the woman invites her out to a hotel for a girls night, too. Could this get any worse?
