Hatsunejima is full of mysteries, including the town's ever-blooming cherry trees, which are said to grant the most sincere wishes. Rumors also circulate about individuals with supernatural abilities, such as Junichi Asakura, who can view other people's dreams and conjure sweets from nothing. Together with his sister Nemu, he enjoys a peaceful life with his friends at Kazami Academy, though he keeps his identity hidden. His quiet school days are disrupted when he learns that his childhood friend, Sakura Yoshino, has returned from America after six years. She has come for a single reason: to keep the promises she made to Junichi long ago. However, no one realizes that Sakura's arrival is destined to alter everyone's lives—for better or worse.
