Xu Ruyi, a charlatan who has been on the streets for eighteen years, relies on his sharp tongue and superb disguise skills to navigate all the major scams. His life creed is: if you cheat, it will last forever, and the money you earn today will be spent tomorrow.
Until one day, he received a "big business" worth millions - posing as a rich girl from a wealthy family who had been missing for eighteen years. The information given by the other party was perfect, and the reward was something he couldn't refuse. However, when he put on women's clothes and walked into the magnificent Xu family mansion, he realized that things were far from that simple.
In this family, everyone is acting. The real daughter Bai Susu targets him everywhere, the stepmother hides a knife in her smile, the housekeeper behaves strangely, and even the seemingly kind master hides secrets. What made Xu Ruyi even more devastated was that the system told him that if he wanted to survive, he must use his deceitful tricks to cure the heart ailments of everyone in the family under this false identity.
A liar who wants to be a psychiatrist? Or use deception to cure diseases? Xu Ruyi smiled: Isn't this his old profession?
