Kazao is content with his life on Mirai ("Future") Island. Although his parents abandoned him after his birth, leaving him to be raised in an orphanage-like facility, his life is comfortable and he has friends, particularly the lovely Eiko, the girl he loves. However, one night he experiences a terrible nightmare in which he sees himself dying in a motorcycle accident. After that, everything changes. The following day, his parents are miraculously "found," and he is torn from his idyllic life and from Eiko's side to be thrust into a world he knows only from television shows and school assignments. Dropped unceremoniously in the middle of a city with only a sketchy map for guidance, Kazao is saved from wandering aimlessly in search of his new home by the cute and forward Yuu, who turns out to be in his class at his new school as well. Despite his best efforts to accept his parents' sudden return and Yuu's friendly overtures, Kazao cannot shake the feeling that things aren't quite right. Nor can he forget Eiko. Why did his parents wait sixteen years to call him back? And why is the piano the only used piece of furniture in his parents' new house? The mysteries begin to pile one atop the other as the lies fall apart in this intriguing story of future possibilities and innocent romance.
