I Became the Devil's Substitute, and All the Supporting Characters Collapsed

My name is Muchen, I traveled to a wasteland novel, and I became the substitute of a local snake boy who did all kinds of evil! The reason why the local snake boy needs a substitute is because he has made too many enemies and there are many people who want to kill him. Even assassination. And I became his substitute. The person who may be killed at any time will be me... Therefore, I lived on tenterhooks every day, fearing that I would receive a box lunch. But I didn't expect that while I was working as a stand-in, all the supporting characters had their personalities broken, and they all treated me surprisingly well! A girl who has been bullied: "Sir, this is a gift for you, please accept it." A dancer who was once beaten: "I put on beautiful black stockings specially for the young master."
