Emergency doctor Xia Guisheng died suddenly after working overtime continuously and transformed into the vicious female supporting character of the same name in the romance novel she was reading. On the night of the book appearance, she was supposed to have her engagement broken off by the male protagonist Mo Shilai in public for framing the heroine, and she became a laughing stock. Faced with the beginning of hell, Xia Guisheng abandoned the script of reducing intelligence, used professional medical knowledge to save Mu Shilai who had sudden heart palpitations, and turned the divorce contract into a "medical consultant" contract.

During the investigation, she discovered that her time travel was actually related to the secret prophecy of the male protagonist's deceased mother. When the late-night doctor who cures insomnia gradually becomes emotional, and when the conspiracy points the gun at the two of them, can Xia Guisheng use medical skills and wisdom to reverse the tragedy of the original work, and work with Mu Shilai to uncover the truth and heal each other's wounds?
