He is Zhang Xiangbei, the Beimang God of War who is afraid of marriage. In order to accompany his "seriously ill" aunt, he faked his death and retired and transformed into a security guard "Zhang Ruoyu". He was ordered to receive the certificate from Liu Ruyan, the female CEO of Bingshan. In order to force the other party to break off the engagement, he disguised himself as a street kid and committed suicide in every possible way, but secretly rescued Liu Ruyan when he was repeatedly assassinated. Liu Ruyan's heart gradually moved, but in her heart was the God of War who had saved her. It wasn't until the memorial service that the truth was revealed - the "sleazy" security guard was the one she had been dreaming about.
