Shadow Monarch's Requiem - Chapter 19: Coronation of Shadows

Zhu Tong was born in a wealthy family, but the pampered young master suffered from a serious cleanliness addiction, and there were so many things that even God can’t stand it, so he was given a sickness and even coughed three mouthfuls of blood.

The day before his death, he was inexplicably bound to a system.

The system told him that he was actually a cannon fodder villain in a danmei novel who humiliated the heartthrob protagonist and suffered the consequences. If he wanted to survive, he had to find the only one in the novel, the white moonlight, who was not attracted to the protagonist and get full favorability from him.

In order to find him, Zhu Tong changed schools.

The new school was located in a remote small county with eight-person dormitories, a canteen for big pot meals, and only one public toilet in a teaching building.

Zhu Tong: In order to survive, he will endure!
