Lin Shutong passed through the book and became the notorious "venomous tongue and seductress" third girl in the Hou Mansion, and was bound to the "Villain Development System" - she must complete villain tasks such as framing and suppression to gain points, otherwise she will be wiped out. In her previous life, she was killed by a traitor who was a domestic servant and a vicious cousin. She used the system's golden finger to save herself: On the surface, she continued to control the world, but in fact, she used the "mind reading skills" rewarded by the system to see through the traitor's conspiracy. When the identity of the "disaster" predicted to "kill the whole family" is about to come true, can she find a balance between the system's mission and sincerity, and rewrite the ending of sadomasochism?
