Twenty years later, one evening as you drive home, the melody from the movie starts playing on the car speakers. The moment you hear the first note, a rush of emotions floods over you, just like that night twenty years ago when you heard them for the first time.

A story intertwined with time and space is destined to be difficult to explain logically, but this film happens to be a love story rather than a science fiction film. Love does not require logical explanations.

The most touching aspect is not the story of the first love at 17, nor the reunion after 7 years, but the commitment to stay together for a lifetime until old age, and the mutual agreement to hold hands and leave this world together in the next life.
