Yuichi Aizawa returns to the snowbound town where he spent childhood vacations, moving in with his aunt Akiko Minase and cousin Nayuki, though he has forgotten much of what happened on his earlier visits. As winter settles over the town, chance reunions and new faces, among them Ayu Tsukimiya, a girl searching for something she lost, slowly draw his buried memories back to the surface. This 2002 Toei Animation adaptation runs thirteen episodes and predates the later Kyoto Animation version.
