After her mother remarries, high school student Haru Kusaka feels like she no longer has a place to belong. Drawn to Rio Fujiwara, a gay young man she meets at the café where she works, Haru impulsively asks to live at his shared house. With no rooms available, the two begin sharing a room under one condition: Haru must never fall in love with Rio as a man.
Shortly after moving in together, Haru is shocked when a half-asleep Rio suddenly kisses her, leaving her unable to stop thinking about him. Having once fallen for someone she never should have loved, Haru tries to suppress her growing feelings, but things become even more complicated when Rio’s casual lover, Tomonori Iwakura, visits the shared house and boldly kisses Rio right in front of her.
