The film traces the life of Tōno Takaki from the elementary years to adulthood. From a young age, Takaki has become accustomed to relocating according to family affairs. Each part of the film in turn tells viewers the milestones in his life. Finally, how will a childhood friend and memories with promises, a breakup, and tears affect Takaki in life still stretching ahead? Will he forget the past, and look to the future or still torment, nostalgic for a distant memory? The answer seems to be for the audience to answer after the movie ends.
