Plot summary.
The series follows Nobara Sumiyoshi, a 15-year-old tomboy with a passion for volleyball. Her love of the sport is disapproved of by her mother, who wishes for Nobara to become the next hostess for their family's "ryotei". Frustrated by her mother's constant pressure and frequent comparisons between herself and her sister, Nobara finally decides one day to move out and make it on her own. After seeking out her aunt for help, Nobara ends up living with four members of Crimson Field High School's boys' volleyball team as their dorm mother. What follows is a drama of a girl's dream of making it into volleyball, and her difficult journey in fulfilling that dream.
Unfortunately, the Crimson Field girls' volleyball team has been disbanded due to lack of interest and some meddling by her mother. Nobara successfully reinstates the team after challenging the boys' team in a three-on-three game, winning, and recruiting three more members to the team, including star setter Tomoyo Osaka.
Before her first official match, Nobara learns her sister Soka has been forced to go on a date with a politician's son. Soka calls Nobara two hours before the girls' volleyball team's first game and she runs to Soka's aid. Following Soka's rescue, she witnesses Nobara play volleyball and sees how truly happy Nobara is while playing. The sisters make a deal with her mother to allow Nobara to play volleyball until she graduates high school, when she will inherit the inn. Until then, her sister will assist their mother in running the inn.
