Shao Xing, a hard-blooded mercenary who emerged from the flames of war, hid in the city after retiring and opened an unremarkable security company. He is cautious in character and ruthless in his actions. His only weakness is his careless family - the family members who dote on him all think that he is a "poor little" who needs to be protected. Until one day, Bai Yueguang and Song Qing, who had broken up due to a misunderstanding, landed as his new neighbor. Along with this, there were overwhelming malicious rumors that he was a deserter who relied on women to gain power and betrayed his comrades on the battlefield. Faced with the return of his old love and the rumors, Shao Xing originally wanted to deal with it in a low-key manner, but he found that the "relatives and friends" around him were the first to explode: the grandfather who founded the state banquet master wanted to prepare a "Manchu-Han banquet" for him to support the occasion, the sister of a top law firm partner wanted to sue the other party and bankrupt him, and even the brother next door who grew up watching him and is now a top idol also posted public support on Weibo. Under the high-profile "group pet" protection of his shortcomings by a group of people, Shao Xing was forced to embark on a road where "the identity of a big boss cannot be hidden" in a dumbfounded way, allowing his old love to see the truth and pursue her husband again.
