Xie Chuntang, a modern-day wedding host, unexpectedly transmigrates into the 1980s and becomes the newlywed daughter-in-law of the Qin family, only to inherit a terrible reputation for stealing money and eloping with another man. Armed with her knowledge of the original novel's plot, she frantically grumbles in her mind while trying to change the Qin family's tragic fate. What she doesn't know is that her mother-in-law, Zhao Guihua, can actually hear her inner thoughts. So while Xie Chuntang says nothing aloud, Zhao Guihua secretly acts on every spoiler in advance: catching scammers, protecting the family fortune, organizing wedding banquets, and starting businesses. One desperately tries to keep her secret hidden, while the other quietly listens to revelations about the future. Together, this unlikely mother-in-law and daughter-in-law duo gradually transforms the once-chaotic Qin family and leads them toward a brighter new life.
