Yuzu Aihara transfers to a strict private girls' school after her mother remarries, expecting to use the fresh start to make friends and perhaps experience her first romance. Her flashy appearance immediately collides with the school's rules and with Mei Aihara, the cold student council president who tolerates no violation.

After her first day, Yuzu returns home and discovers that Mei is not merely a difficult classmate but her new stepsister. Their forced closeness makes Yuzu's feelings increasingly confusing, especially as she notices the pain hidden behind Mei's severe exterior and her desire to understand her begins becoming attraction. Caught between a new family bond and emotions she does not know how to categorize, Yuzu tries to reach a girl who has made a habit of pushing everyone else away.
