A group of young girls who all attend a "girls-only musical school", recount the formidable years they shared, at times shifting between different characters' viewpoints and time. Awajima Musical School Training Camp, dubbed the "boarding house", is where young girls gather from all over Japan to perform on stage: Tabata Wakana aspires to be a musical star; housemaster Takehara Kinue attends to carry on her best friend's wishes; beautiful Okabe Emi is a scholarship student always at the center of attention; and Ibuki Katsurako who became a teacher at the school though originally from a family of actresses.
