Hatsunejima is riddled with mysteries, one of which being the town's evergreen cherry trees, which are claimed to grant the most genuine requests. There are also reports of persons with supernatural abilities, such as Junichi Asakura, who can read other people's dreams and make sweets out of thin air. He likes living in peace with his friends at Kazami Academy, with his sister Nemu, but wishes to keep his identity hidden. When he learns that his childhood buddy Sakura Yoshino has returned from America after a six-year absence, his peaceful school life grinds to a halt. She is just there to fulfill the vows she made to Junichi a long time ago. Nobody knows, however, that Sakura's presence will affect everyone's lives—for the better or for the worst.
