As a favorite of Emperor Qianlong, Xiao Shenyang had great power in North Korea, but his corrupt behavior also caused dissatisfaction among some officials. Violette is an upright official. He once impeached Xiao Shenyang, but failed because of Xiao Shenyang's influence. In order to protect his own interests, Xiao Shenyang didn't want Violet to be his enemy again, so he cheated Violet and said he was an honest official.
This behavior led to violette's misunderstanding and resentment towards Xiao Shenyang, believing that Xiao Shenyang was a hypocrite and distrusted Xiao Shenyang. In the end, this contradiction led to the separation between them, which made Xiao Shenyang feel sorry for Violet.
