As a concubine of the Jiang family, Jiang Yue was treated harshly by her aunt Zhang and her eldest sister Jiang Lingyun since she was a child. Her mother was tortured to death and she was severely injured by her eldest sister. She suppressed her plans and planned to poison Jiang Lingyun, and then took the opportunity to fill her brother-in-law Pei Jing's house. After entering the Marquis Mansion, she worked step by step, using Pei Jing's compassion and integrity to expose the evil deeds of the Jiang family. She also uncovered evidence that Jiang's father colluded with the King of Qi to secretly mint counterfeit coins, and successfully brought down the Jiang family to avenge her mother. Fearing that Pei Jing would be held accountable, she faked her death to escape, but was found by Pei Jing a year later. Her brother-in-law, who had been scheming against her in every possible way, had already fallen in love with her, and the entanglement between the two began.
