Beach Boys

A recently dumped free spirit and an unlucky businessman unexpectedly meet on the way to a beach and start staying at a small guest house by the sea.

Kaito's girlfriend comes to the Diamond Head, as does Hiromi's ex; that night, Kaito learns that Hiromi was once a swimmer with Olympic aspirations.

Kaito returns to his company to work on a project; Hiromi sets out for Tokyo to do a favor for Masaru but finds an unexpected passenger in his car.

Kaito's former boss arrives at the guest house to find out why Kaito would give up his career; Makoto learns that Masaru wants her to meet her mother.

A man arrives at the Diamond Head saying he's the swimmer who went to the Olympics in Hiromi's place and that he wants to settle things with a race.

Ahead of an annual fireworks show, Kaito feels dejected when Sakura decides not to come; Haruko alters an old summer robe to give to Makoto.
