Emperor Yan Sui of Great Yan went on a patrol incognito, encountered an assassin, and was seriously injured. He was rescued by Yun Yifei, the magistrate of Laiyang County. While recovering from his injuries, he gradually developed a liking for Yun Yifei, confessed his love to Yun Yifei, but was rejected, and then forced him to force him through drunkenness. The two had a cold war. Yan Sui took the opportunity to return to the palace, dismissed the harem, gave way to his uncle, and returned to Laiyang County to start pursuing his wife.
