Taiki Inomata loves badminton, but he has a long way to go before he can reach nationals. When Taiki sees upperclassman Chinatsu Kano practicing her heart out on the girls' basketball team, he falls for her hard. After an unexpected turn of events brings the two closer together, sports might not be the first thing on their minds anymore!

The joint training camp has begun, and Taiki must endure even tougher practices than usual. But all he can think about are Chinatsu and Hina! During the final night of the camp, Taiki finds himself alone with Hina once again and realizes he needs to be more honest with himself--and with her.
