Kou spends fifty episodes learning that the person he was supposed to love was never the one standing next to him. The show moves like real time, letting you sit in the space between what characters want and what they actually need, until the difference breaks something open. This is a sports anime that barely cares about baseball, a romance that earns its ending by making you feel every ordinary moment before it arrives.

Kou grows up straddling two neighborhood institutions: his family's sporting goods shop and the Tsukishima batting center next door. The two families are so intertwined that Kou practically lives at both homes, especially spending time with Wakaba, who shares his age. Her younger sister Aoba resents how much of Wakaba's time Kou takes up and insists she hates him. Aoba has a real gift for baseball, with excellent pitching form. Kou says he has no interest in the sport, yet he secretly trains to become as good as she is, and his hitting has been sharpened by years at the Tsukishima batting cages. Wakaba often ends up sparking the constant bickering between the two, and baseball may be what helps them get past their own struggles. The story mixes sports drama with comedy and romance.
