How is the theme of excellent animation gear reflected?

Gear is an animated short film edited by 30 artists for five months, which tells the story of two children living in the same city and different worlds. The people in the video, with their feet fixed, walk in the established trajectory of life, unable to intersect, are expressionless, step by step, like walking dead. It is puzzling that for a long time, no one has questioned and protested this. Everyone silently accepted this reality and endured it again and again! Finally, this day was changed by a boy who broke free unexpectedly. He was desperate to get rid of the shackles that bound his feet, and finally inspired everyone in the whole city to get their own choice!

The theme of this animated short film is about the struggle between human free will and destiny.
