His father has been missing for ten years, and Xie Heng has been the most peaceful second girl in the Xie family for ten years.
The younger sister refused to marry the prince of Zhenbei, who was seriously ill, so she was sent to the prince's mansion on a sedan chair. On their wedding night, Lu Tingzhou handed over a imitation suicide note, leaving only one sentence on the paper: Don't believe your mother.
Xie Heng saw that the handwriting was fake, but he saw the secret message left by his father in a leftover page. An old case that had sunk at the bottom of the Anling River resurfaced. The mother who took care of the house gently, the sister who suddenly changed her mind, and the husband who was seriously ill all had things they could not say.
She originally wanted to live a stable life in the Hou Mansion, but she had to join forces with Lu Tingzhou to find out whether her father was alive or dead, the Xie family's old accounts, and who wanted her to stay in this substitute marriage forever.
