World view: A world opposite to humans. Some animals have the same intelligence as humans, or have intelligence higher than humans. They behave in human form, while some animals are still in the state of four-legged beasts. Humans were very rare in that world, so they became pets of superior animals and kept them at home. Human beings in that world are affected by radiation and stop growing after their bodies grow to a certain point, but their age will increase year by year, and their average life span is similar to that of people on Earth. Humans will be found in pet shops and high-end homes. Generally, there will be no strays, because the price of humans is still quite precious. In a world that is exactly the opposite of the human world, can the heroine survive in the cracks of such a different world and find a way to return to her original world? There is an unknown connecting channel between the two worlds. Who is behind it all? Are the animals in the human world gaining intelligence, or are the humans in another world rebelling? What kind of secrets are there under the main pet?
Purpose: Both humans and animals are equal
