After a failed strategy mission, the heroine traveled back to before the story began. She decided to abandon the system and "sincerity" and live only for revenge and freedom. She used the cold mind and Machiavellian tactics she learned from the villain in her previous life to transform herself from a concubine in the prince's palace into the "perfect" princess in the eyes of everyone. However, just when she thought she was about to succeed, the sinister and paranoid villain who was supposed to forget her appeared again and dragged her deeper into a cage in an even crazier way. In the court, court and emotional confrontation, the two launched a life-and-death game mixed with hatred, pain and twisted dependence.
