Zaizai accidentally entered the children's paradise - Fantasy City.
Here, there is no need to do homework, no restrictions, just endless fun and freedom. It has everything children want, including food, amusement parks, magical new worlds, and even the huge power to control the entire city.
But all the good things seem to make the children gradually forget "who they are", as if they are turning into animals...
Facing temptation, can Zai Zai and his friends defeat them? Can Zai Zai find his way home? Who is the real hero?
Concept: Freedom has limits
