Taiki Inomata, a third-year junior high student at Eimei Academy—a school renowned for its strong sports program—joins the high school badminton team. Determined to improve, he always arrives early for open practice, yet no matter how early he comes, he’s always second. The one who beats him there is Chinatsu Kano, a first-year high school student—and Taiki’s crush. Chinatsu is a rising star on the basketball team, and the gap between her and Taiki seems enormous. While Taiki is a skilled badminton player, he lacks her fame and presence, making his feelings seem hopeless. But in an unexpected twist of fate, Chinatsu ends up living in Taiki’s house! Determined to stand by her side as an equal, Taiki sets his sights on the same goal as Chinatsu—to compete in the Nationals. With newfound motivation, he trains harder than ever, all to become someone worthy of the girl he admires.
