Fu Zheng, a veteran who valued love and justice, was entrusted by his comrades to take care of his sister Shen Qingxue before they died. By some mistake, Shen Qingxue was supposed to marry Gu Shaochen, the heir to the business empire, but due to the scheme of her sister Shen Yurou, Shen Qingxue was changed into a sedan chair and married to Gu Yan, the good-for-nothing illegitimate son of the Gu family. In order to protect Shen Qingxue, Fu Zheng took the initiative to marry into the Gu family and became a bodyguard and husband. Unexpectedly, this seemingly useless consultant is actually the real helmsman of the hidden business empire. When Shen Yurou proudly married into a wealthy family with a dowry, she found out that the so-called good-for-nothing son-in-law was using her family's assets for charity; when she tried her best to get Gu Shaochen to inherit the family property, she was told that all the equity was already in Gu Yan's name. Fu Zheng walked from behind the scenes to the stage, leading Shen Qingxue on the road to counterattack, using his fists and wisdom to put an end to all schemes. This was an accidental marriage, but it turned out to be the most domineering marriage.
