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.
Mochizuki was the first person besides Hayao Miyazaki and Isao Takahata to direct a Ghibli feature when he adapted the Umi ga Kikoeru high school romance novel by the late Saeko Himuro in 1993.
