The setting is Shonan, Enoshima. A town where the nostalgic and the fresh coexist.
All his life, high school student Yuki has never had a friend of his own, because he's freakishly inept at communicating with others. Haru, a self-proclaimed alien from outer space, is trying to get him to go fishing. Natsuki is a local boy born and raised in Enoshima, who always seems to be annoyed by whatever's going on around him. Akira is a mysterious Indian boy who watches over them all, while maintaining a cautious distance.
