A badminton guy falls for a basketball girl. Do these sports-crossed lovers have a chance?

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!

Winter break is rolling in, but Taiki and Chinatsu won’t be spending it together. Despite a ski trip with his badminton buddies to keep his mind off her, Taiki holds on to the faint hope that he’ll be able to see Chinatsu before school starts again. The time apart has only intensified his feelings for her—and Taiki finally decides it’s time to act!
