Rinsen Academy’s Miyako and Touyou High’s Nora are promising swimmers. In elementary school, Miyako called out to Nora, who couldn’t get used to his surroundings, and since then they’ve been friends. But Nora started having feelings for Miyako that overcome those of real love. Miyako had accepted that for a while, but gradually began refusing it and grew away from the swimming world. Then one day the two meet again.
