In her previous life, Qiu Wan, a maid from the Lu family, had her heart cut out by her husband Shen Ci and her blood was taken out just to save Lu Zhining, his "savior". She eventually died miserably under the knife of a robber. After being reborn and returning to the day when she was given the marriage, Qiu Wan categorically refused the engagement and saved Pingyang's Mansion with the help of her past life memories. Unexpectedly, she revealed the shocking secret that Shen Ci had deliberately concealed - she was the biological daughter of the eldest princess who had been lost for many years, and the "Bai Yueguang" Shen Ci had guarded for many years was actually the counterfeit that stole her life. With his identity restored, Qiu Wan watched his enemy fall into the abyss with cold eyes, and Shen Ci was heartbroken in front of the truth.
