Konatsu Miyamoto, a third-year student at Shirahamazaka High School, wants to participate in the annual music recital. However, after messing up the year before, the vice principal has denied her permission. To circumvent this, Konatsu decides to form her own singing club with friends, including Wakana Sakai, who has abandoned her singing ambitions. With only a month to find members and prepare, Konatsu faces the challenge of making her club a success.
