Modern best friends Sang Luan and Meng Youning transmigrate into an angsty novel, becoming the primary wives of Chief Councilor Feng Hengzhi and Heir Qi Ran. In the original work, the white moonlight returns from the dead after a year, and both are sentenced to death. To save their lives, the sisters outwardly obey their husbands while secretly striving to save money. At a palace banquet, they risk giving a tip-off to crack a major assassination case; Sang Luan declines a reward from the emperor, wishing only for a prosperous era, earning the emperor's appreciation, while Meng Youning stuns everyone with a rendition of Yellow Plum Opera. They buy a rouge shop in the south of the city, and once they save up twenty thousand taels, they plan to divorce and live in seclusion. The cold-faced chief councilor acts disdainful, but breaks through a window to save her, fixing her hair and giving her instructions; the wayward heir sees Meng Youning scared faint and panics out of control. Both husbands say one thing while meaning another, making their path to running away increasingly turbulent.
