Rikka lives in a Share House in Tokyo, making a living by working as a freelance artist. Since the third tenant moved out recently, it's a good opportunity for her to get closer to her House Mate Sena. They just started as normal friends, but with the time passing, they get closer and closer. Soon there was no doubt left, that Rikka and Sena felt more for each other than friendship. Will Rikka fall in love with another woman, besides being a woman herself?!
