A story about a comatose person who fantasizes about having a second personality after a car accident. He goes back to the past to parallel his childhood self and becomes his second personality (pseudo) in a parallel world.
(I know the above is very convoluted, but let's go through it anyway)
Seriously:
This article writes about the nearly three years that Su Ge traveled to the past to replace his imaginary second personality No. 2 Due to an accident, and spent nearly three years with his past self.
Intention: to entertain oneself
