The story begins with an unexpected marriage. The heroine possessed by a modern soul clearly knows that she is just a "stand-in" who was pushed out to make up for her eldest sister after she escaped from marriage. It is also rumored that she is the shadow of Bai Yueguang in the heart of the Chinese father-in-law. In order to save her life in the dangerous compound, she decided to play the role of a meek and respectful puppet lady. During the day, she was a flawless lady, while at night she secretly counted her private money and planned her route. When the time was right, she would fly away and live a free and easy life.
The male protagonist, the powerful and ruthless duke-in-law, saw through all her disguises from the beginning. He watched with great interest his little lady's "dedicated" acting every day, taking in all her careful little movements and pretending to be calm, as if he was enjoying an interesting cat-and-mouse game that was exclusive to him. He calmly cleared the obstacles for her, and set up checkpoints in a playful way, enjoying the vivid appearance of her racking her brains and trying hard to deal with him in order to "escape".
As a result, a tug-of-war of "she runs away, he chases" quietly unfolds. Just when she thought her plan was perfect and she escaped successfully, she was always "picked up" by him easily at critical moments. It wasn't until she finally couldn't bear it anymore and ended her relationship with Li Shu that the man who had always been strategizing panicked for the first time. Only then did he suddenly realize that he had already been trapped in it. What he wanted was not a substitute, but the unique soul in front of him who only wanted to escape from him.
