Running in both directions
When they first met as children, Lu Huai recognized Shen Xingyue
When they met again when they were young, Lu Huai kidnapped and deceived Shen Xingyue into marrying him back to the Hou Mansion.
This is a reunion after a long absence, a renewal of the relationship. But Lu Huai has a purpose?
"You approached me just to investigate dad?"
"You and I got to know each other first, and were ordered to investigate the case later. I have never used your relationship to investigate. Today's search of the Shen family is an act under orders. It is my personal affection for you to plead with the emperor for the innocent people of the Shen family."
