Fu Yu never believed in ghosts or gods. However, after her High School entrance exam, she had a dream: the world she lived in was a book.
"What a joke," she thought. "Studying for so many books for the entrance exam must have exhausted my mind." She initially dismissed the thought that her world could be a book.
She laughed it off at first, but when the dream returned every single night, she started to take it seriously. In the dream, her older sister was the real rich daughter, and her own biological sister was a fake rich daughter. But that wasn't what mattered; what mattered was that she was just a cannon fodder character in this book.
Because her parents didn't care about her, she became rebellious. She was good at studying, but she intentionally started skipping classes to get her parents' attention.
That wasn't the worst part, though. The worst part was that everyone else got a happy ending, while she became a drug addict and ended her life by committing suicide.
She was still skeptical about the dream, but she couldn't ignore it. When the parents of the real rich daughter came home, she knew it wasn't a dream—it was reality. She was truly scared: Why would she become a gangster, get into fights, and become a drug addict?
