Ye Ke travels into a male-domestic post-apocalyptic upgrade novel, but she is not a beautiful heroine in a prosperous age, nor is she a gifted second female lead.
Rather, it is a male protagonist who has abused a pretty boy since he was a child and did all the bad things and was eventually turned into a villain. He takes revenge on the vicious female partner who ends up miserable.
Her mission is to prevent the male protagonist from going dark
When the mission was completed and she patted her butt and left, the handsome male protagonist whom she had raised turned into a black man in the blink of an eye.
