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!

To celebrate everyone's hard work at nationals, Taiki and the rest of the badminton team head to the beach. As luck would have it, Chinatsu's there for the basketball team's summer training camp! But instead of a fun, relaxing break, Taiki must endure the trials of an old friend to prove he deserves to be with Chinatsu!
