This short film is based on my childhood memories and is a dream that flows back from the present to the past, where an urban story contains the minutiae of people's emotional lives that can be reflected through the city's changing.

In my vision of the film, I want to see the story flow gently, slowly, sometimes pleasant, and occasionally bitter sarcasm when I see that people's love and memories are not entirely intact in the face of urbanization. In the film, fragments of a man's memories of his wife are recalled back, but they are all things that cannot be returned, cannot be seen, or revisited with the original appearance. That seems to be an inevitable miss that people will encounter in this changing country.

In the film, the cloud is mentioned as a metaphor for something vaguely in the past, something invisible. Still, one can easily feel its familiarity and feel nostalgic: "Sorry, I seem to have missed something important."
