While carrying out her family's revenge mission, Shen Yan accidentally exposed her identity and was entangled by a mysterious villain - who was not only sinister and cunning, but also had an almost crazy possessive desire for her. In order to stabilize her spirit and find out the villain's flaws, she found the legendary psychiatrist Lu Chenzhou. Lu Chenzhou was a natural master of strategy and could always see through her disguise at a glance. He was extremely possessive, but he kept pace with the treatment and brought her into his protective circle. As the mission progresses, Shen Yan begins to doubt himself and even shows signs of schizophrenia, and the villain's punishment methods become increasingly bizarre and cruel. In a psychological game and life-and-death contest, she and Lu Chenzhou not only had to fight against the villain, but also uncovered the truth about family hatred. However, they gradually discovered that the villain's conspiracy was far more than just revenge.
