The story begins with an "accidental" rebirth. The soul of modern forensic doctor Su Wan was transformed into Su Jinse, a concubine of the Prime Minister's Palace. She was abandoned and raised by Zhuangzi since she was a child, and was notorious for being "sick and weak" and "restraining relatives". It happened that the Queen Mother in the palace was seriously ill and needed to find someone with "compatible destiny" to make her happy. She was regarded as an abandoned child by her family and was sent to the palace to become the Queen of Happiness. Everyone regards her as a living sacrifice, including the Queen Mother Huo Yaoguang (the villain) who is lingering on the sick bed and has unpredictable temperament. However, Su Jinse is no longer the original owner. On the surface, she is submissive and frail, but on the inside she is thoughtful and thoughtful. She uses her forensic knowledge and psychological foundation from her previous life to solve a series of seemingly unexpected "sickness death" cases in the palace, and quietly weaves her own intelligence network. She unexpectedly gets acquainted with Xiao Jue (the male protagonist), who is cynical on the surface but actually carries a blood feud. The two initially explored and exploited each other, and gradually established a subtle trust and alliance while jointly dealing with the yandere-like persecution of the Queen Mother Huo Yaoguang, who was extremely controlling and treacherous. The plot revolves around how Su Jinse uses her special identity as the "Queen of Chongxi" to survive, break through, and fight back in the complex network of forces of the queen mother, emperor, courtiers, and relatives. She needs to resolve the morbid control of the Queen Mother, fight against the family's use and betrayal, and at the same time assist Xiao Jue to uncover the conspiracy behind the two countries. In the end, she will reveal the deepest secrets and twisted past of Queen Mother Huo Yaoguang, complete a shocking reversal from a "happy sacrifice" to a real person in power, and realize the double redemption of herself and the times.
