Li Xingwan set up a system.
Although, she does not suffer from any incurable disease and lives a happy life. But, the reason why the system found her is not important, as long as she can make money!
The system told Li Xingwan that the world she was in was actually a book.
Li Xingwan: "Am I a vicious supporting actress?"
System: "No."
Li Xingwan: "Am I a cannon fodder?"
System: "No."
Li Xingwan: "Then what role am I?"
System: "... Pure passerby."
Li Xingwan:?
Concept: Everyone is the protagonist in their own life.
