Three years ago, in order to investigate the collusion between the Chiyan Department and spies from North Korea and China and obtain border intelligence, he sneaked into Chiyan under a pseudonym and took advantage of Yun Zhao's feelings. Later, in order to avenge his mother, he destroyed Chiyan's important stronghold (i. E. Yunzhao's mother tribe) and launched a raid, causing a tragedy. He has complicated emotions towards Yun Zhao (taking advantage of her, feeling guilty, being attracted by her light, and later gradually falling in love without knowing it). Marrying her was both a political necessity and a way to bring her under control. Personality: Cold and majestic on the outside, lonely and depressed on the inside. His feelings for Yun Zhao are struggling among suspicion, temptation, possession, guilt and deep love. He is not good at expressing himself and is used to using power and calculation to solve problems, which eventually leads to irreparable tragedy.
