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!

With nationals approaching, Taiki looks for ways to push himself harder than before. He decides to turn to Hyodo, who puts him through a spartan training! Then, qualifiers begin for the girls’ basketball team. Chinatsu leads them through the bracket without breaking a sweat—until she faces off against Yumeka for a spot at nationals!
