In the late Qing dynasty, Cao Jingxing, the second young master of a prominent Shanxi merchant family that runs the Huitong bank, was hopelessly in love with Du Wanning for eight years in his previous life. He squandered the family fortune, only to be locked inside a silver vault by her and burned alive. His father was even forced to kneel in public and beg to preserve the century-old Huitong name. Reborn at the moment he was being whipped by his father and made to kneel in the ancestral hall, Cao Jingxing cuts off his obsession on the spot. He exposes the Du family's tricks in returning betrothal gifts in front of everyone, outsmarts the mole within his own ranks, and foils his rivals' plot to force the bank into insolvency. He transforms the nearly bankrupt West City branch into the capital's leading bank. At a wedding banquet, he then asks to marry Han Zhao, the bold and capable head of a bodyguard escort agency. Together, the couple make the Huitong business flourish.
