Overview
Taiki Inomata trains every morning in the school gym, chasing his dream of reaching the badminton nationals. There, he keeps noticing Chinatsu Kano, a star on the girls’ basketball team who practices just as hard — and he quietly falls for her. Then life throws them together: Chinatsu moves in with Taiki’s family, and suddenly the girl he admired from afar is living under the same roof. Between early-morning practice, tournaments, and the ache of a first love, Taiki has to balance his feelings with his ambition, while his cheerful friend Hina Chono watches from the sidelines with feelings of her own. Blue Box is a gentle, beautifully drawn sports romance about young love, hard work, and the courage to say what you feel.
