How much sorrow is there in life?
An accidental car accident brought Shao Xiaoli into "time".
The so-called "time" refers to the four-dimensional world. In the four-dimensional world, people can control the composition of objects in the three-dimensional world at will.
However, the four-dimensional world is also a human world, with happiness and sadness.
"I never knew why I came here and why I wanted to know this world. Maybe my life is really a joke. The person I loved the most erased all my memories of him in order to protect me; the person I trusted the most ended up becoming the most terrifying enemy; my best friend finally drove me to a dead end. I really can't go on anymore."
