Each year at Shirahamazaka High School, a special recital gives music students the chance to perform before industry professionals and distinguished guests. Determined to sing in her final recital, third-year student Konatsu Miyamoto is devastated when the vice principal forbids her from participating due to a mistake she made the previous year.
Unwilling to give up, Konatsu hatches a bold alternative: if she can’t join the official choir, she’ll start her own singing club with her friends. But the plan proves more challenging than she expected. For starters, her friend Wakana Sakai has sworn off singing altogether—and two members aren’t enough to form a proper club. With only a month remaining before the recital, Konatsu must gather enough members and prepare in time for one of the school’s biggest events, hoping to graduate without any lingering regrets.
