Fake Virgin/Real Ghost Love Brain
When Li Shi was 17 years old, she was bound to a Madonna system calling herself "745". The Madonna system told her that their goal was to save the "weak, pitiful and helpless" villains and bring peace to the world.
This villain turns out to be Tan Tan, whom Li Shi depended on in the orphanage when he was a child, and is also Li Shi's current "strange" classmate.
Li Shi was frightened, Li Shi shouted, Li Shi didn't want to!
But adhering to "for the happiness of the people of the world" [bs]
The Holy Mother System said that she could tell Li Shi everything about Tan Tan's disappearance.
Finally! With their unremitting efforts, the villain's favorability dropped again and again, and Li Shi finally got together with the villain!
