In the future Earth, the world consists of two parts. One is the "wonderland" that everyone yearns for - the safe zone, and the other is the real world - the foggy forest, which is extremely developed but never sees day and night.
Xuanri was "lucky" to be born in the foggy forest, and when he was eighteen years old, he met his human world.
"You have made my world no longer boundless. This is reality, a reality with sharp edges and clear boundaries."
