In her previous life, Su Qingyan was the most talented widower in Dali Temple and the secret lover of Xiao Jue, the powerful King of Jingan. She devoted her talents to helping him solve countless cases and eliminate his political opponents. However, on the eve of his ascension to the throne, she was sentenced to death for "deceiving the public with evil words and defiling the palace", which became the last stumbling block for him to clear the way for his new queen. Reborn with hatred, back to the time when all the tragedies had not happened, Su Qingyan just wanted to stay away from Xiao Jue, rely on her unique autopsy skills to live in peace and protect her family. However, what she didn't expect was that Xiao Jue in this life seemed to also carry memories from his previous life. The man who used to be indifferent and taciturn was now like a piece of dog-skin plaster that couldn't be shaken off, tightly imprisoning her under his wings with an almost paranoid attitude. During the day, he was the decisive and murderous King Jing'an; at night, he knelt humbly in front of her bed, kissed her hand over and over again, and begged in a mute voice: "Yanyan, believe me again, don't let me go." Only then did Su Qingyan realize that there was another hidden meaning to her death in her previous life, and this man had already loved her to the core. Amidst numerous mysteries and court intrigues, the two work together to uncover the truth about their past lives, change their destiny, and ultimately stay together for the rest of their lives.
