When a doctor of psychology transforms into a vicious female supporting character in a sadistic novel, she uses a high-IQ PUA to turn the "villain mission" into a "group pet raising", proving that the real manipulation is not to hurt, but to make people willing to be healed.
Dressed as a vicious female protagonist in a sadistic novel whose kidneys and hearts were ripped out by the male protagonist, she was bound to the villain system and asked to "frame the female protagonist and harm the male protagonist." As a result, she did the opposite - being gentle and considerate to the male protagonist, and loving the female protagonist's sisters. She used "repaying evil with kindness" to turn the abusive novel into a healing and sweet one, which made the system angry to the point of death.
