Chika Homura starts her high school journey with a single aim: to cultivate a "cute girl" image that will win hearts.
Despite being an all‑star on the volleyball squad, she leaves that team and opts to join the school"s overlooked Wind Instrument Club, choosing the flute as it feels the most gentle and ladylike.
After nine years apart, Chika finally meets her childhood companion and complete foil, Haruta Kamijou, who has grown into a sharp, stoic figure.
Sadly for Chika, Haruta does not buy into her attempts to appear more charming; he sees through the facade.
Yet Chika persists, falling for the music teacher Shinjirou Kusakabe—an affection Haruta shares as well, sparking a subtle rivalry.
Still, Chika"s high school days refuse to go as planned when odd puzzles surface around her and her squad, threatening their harmony.
The wind‑instrument crew must unite to crack the enigmas haunting their campus while also recruiting new players for upcoming contests, hoping to win regional championships.
