Xie Yunwan, the legitimate daughter of the Marquis of Jingyuan, used her sex to serve people at palace banquets and mingled with dignitaries. On the surface, she was the number one socialite in the capital, but in fact she was the mastermind secretly manipulating the intelligence network. She was ambushed by assassins during the banquet, and she was forced to rescue the seriously injured chief minister Pei Yun. The two had an ambiguous confrontation in the darkroom. The next morning at court, Pei Yun asked for a marriage in public. The bride turned out to be the woman who almost killed him last night. Everyone in the court knew that the chief minister was not a womanizer, but no one knew that he had been eyeing her for three years.
