Ocean Waves is a high school love story set in Kochi, Japan. Morisaku Taku and Matsuno Yutaka are best friends when a girl from Tokyo named Muto Rikako transfers to their school. Excluding herself from group activities, she's eventually labeled a snob. Matsuno has a crush on Rikako, so it's no surprise that he gets a little jealous when Morisaku and Rikako start spending more time together. The rumors around school get worse, but Morisaku still insists there is nothing between him and Rikako.
