Kenji is a teenager with a secret crush on fellow student Reiko. Reiko, though, fancies Arai, the hunky star of the swimming team. She asks Kenji to help introduce her to Arai, as both boys are on the same team. Arai realises how Kenji feels about Reiko and backs off, but Kenji still goes on his first date with Reiko and finds her with Arai.
