アオのハコ

Every morning before class, Taiki Inomata arrives at the gymnasium to practice badminton alongside the girls’ basketball team. It is there that he watches Chinatsu Kano, a graceful upperclassman who commands the court with quiet determination. Her dedication to the sport inspires Taiki to push his own limits, but his admiration is more than athletic. When an unexpected twist of fate brings Chinatsu into his home, the distance between them collapses, and the two find themselves navigating the delicate space between friendship and something deeper. Taiki wants to qualify for nationals in badminton. Chinatsu wants to take the basketball team to the top. These parallel ambitions bind them together, but every stolen glance and unspoken word threatens to tip the balance. In this high school where morning practice holds the hopes of athletes and the tension of a quiet crush, Taiki must decide if chasing his dream also means risking his heart.

A badminton hopeful and a basketball star share a gym floor each morning, but when circumstances force them closer, their quiet admiration begins to blur the line between sport and love.

Discover Blue Box, a heartfelt sports romance where a badminton player and a basketball star navigate ambition and first love under the same gymnasium roof.
