White Deer is a policeman's undercover, and approaching Lu Xinghe is actually to solve the case, while the person White Deer likes is Joo Won?, the leader of the major crimes unit. As a police undercover close to Lu Xinghe, Bailu certainly knows Lu Xinghe's true face very well. The police all know that Lu Xinghe is a murderer and has done a lot of illegal and criminal things, but failed to find evidence of Lu Xinghe's crime, so Bailu approached Lu Xinghe just to find his criminal evidence. Of course, she won't like Lu Xinghe, and finally she finished the task.
Lu Xinghe likes Bailuyuan, and his eyes are blinded by love. He never doubted the true identity of the white deer. He didn't know that White Deer would be the undercover of the police, so he was very depressed when he learned the truth after being arrested.
As a shrewd and cold-blooded businessman, Lu Xinghe certainly won't trust others so easily, so as a policeman undercover around Lu Xinghe, White Deer saved Lu Xinghe when he was in danger and was injured himself.
Bailuyuan successfully attracted Lu Xinghe, made him like himself and lost his judgment. The reason is that Lu Xinghe knew that White Deer didn't like him, but as in Joo Won?, Lu Xinghe kidnapped White Deer in order to separate it from Joo Won?. But as the protagonists of the official pairing, how can Bailuyuan and Joo Won? be separated so easily? Of course, the villain had to be killed, so Lu Xinghe was finally killed by a sniper.
