What are the wonderful plot designs in the animation "Son of the Weather"?

Son of the Weather is a wonderful animated film with many wonderful plot designs. The following are some plots that I think are more exciting:

1. The music in the movie is very nice, including many classic Japanese pop songs.

2. The painting style of the film is very beautiful, especially this film has many large empty mirror images of the sky, light and shadow combined with the city, and each frame can be used as wallpaper.

The emotional line between the hero and heroine in the film is very touching, and the interaction and dialogue between them is very interesting.
