Cheating Men Must Die

A brief description of the manhwa Cheating Men Must Die:

“I always thought the bastards were cool.”

Destroying one scumbag gives you a moment of satisfaction, but the life spent destroying the scum is a life full of enjoyment… Su Lüxia, our protagonist, travels the worlds and helps abandoned women to regain justice with the help of the “System of Revenge of Secondary Women’s Characters”.

Su Lüxia: “The only thing that can comfort me is the tears of repentance of the dead and the pain of prostitutes.
System: “Is my mistress alive today? No.”
