As Hanabi Natsuno returns home after six years in Tokyo, memories flood into her. As she prepares to start high school, she moves to Tachibanakan, the local dormitory for female students. Upon her arrival, Hanabi stumbles upon a bare naked beauty, and instantly falls head over heels for her. She also reencounters Konomi Fujiwara, her childhood friend who she barely remembers.
