Lin Zhaotang was forced to marry by his maternal grandfather's family. On the night he escaped from the marriage, he accidentally broke into the scene where the chief minister Pei Yanci was interrogating the spy. She just wanted to save her life, but Pei Yanci recognized the old sachet on her body. The next day, Pei Yanci came to ask for marriage in person. She married into the Xie Mansion and used the power of the chief minister to investigate her father's old case; Pei Yanci married her just to protect her under his nose. She investigated step by step and found out that her father was not dead, that the old case was false, and that what really needed to be uncovered was a secret royal case that could overturn half of the court - and the chief minister who slept with her every day already knew everything.
