Shen Yizhen, the concubine of a merchant, was forced by her aunt to marry Pei Su, the eldest son of the Hou family, who was rumored to be about to die soon, instead of her aunt.
Everyone was waiting for her to fail and become a widow.
On the night of their wedding, Shen Yizhen discovered that the frail prince, who couldn't even get out of bed, climbed out of the window to kill someone in the middle of the night.
At the same time, relying on her ability to check the family's accounts since she was a child, she discovered from the Hou Mansion's account books: tens of thousands of taels of silver disappeared every year in this seemingly impending Hou Mansion, and this money was related to an old case of massacre of the Shen family ten years ago.
One of the two pretended to be sick to investigate the military pay case, and the other pretended to be stupid to investigate the death of his mother.
They initially tested each other and used each other, and finally became the only person who could support each other.
