After Getting Her Body Back, the Mistress Takes Revenge and Marries Both.

In order to get her body back, she waited for three lifetimes. In these three lives, she watched helplessly as the time-travelling woman used her body to have a sadistic love affair with a scumbag. She hated them so much that now she could finally cut them into pieces with her own hands. Later, she cheated all the way on her way to revenge, and many people commented that her methods were too ruthless. The former indifferent regent protected her behind him. "It doesn't matter if I kill a few scum for my people."
