Kairi Okayasu 岡安浬

A popular and carefree classmate of Momo's. He has the reputation of being a playboy, something he isn't exactly proud of. He thought that Momo was the one who once gave him CPR when he'd nearly drowned at the beach when they were younger - only to later find out he'd been saved by the local lifeguard. His interest in her is renewed when Sae spreads rumors about them being a couple. This prompts him to try and make the 'rumor' come true, by kissing her unexpectedly in the beginning of the series. In the Tokyopop version of the manga, his name is Kiley.
