Every morning, first-year Taiki Inomata hurries to the high school gym to refine his badminton skills. His true motivation, however, is sharing the gym with Chinatsu Kano, a second-year basketball star and his crush. Though she seems distant, Taiki gradually finds chances to connect with her.
Taiki’s dedication inspires Chinatsu to pursue her dream of winning at the national level. When her family moves overseas, Chinatsu stays behind and moves in with Taiki’s family. Overwhelmed by living with his crush, Taiki vows to match her ambitions by excelling in badminton.
Despite his talent, Taiki faces challenges to secure a spot on the team. Encouraged by Chinatsu and his childhood friend Hina, a gymnast, he strives to prove himself against formidable opponents.
