Gu Qingtang, the matriarch of the Lu family, opens her eyes after being reborn and sees her husband's concubine-born daughter, Lu Qiyue, wearing her legitimate daughter's wedding dress and kneeling in the courtyard, tearfully begging her to give up the marriage arrangement. In her previous life, Yining died less than a year after marrying into the Marquis's household, leaving behind a blood-written letter with just one sentence: "If I could live another life, I would rather never marry." This time, Gu Qingtang readily agrees to the marriage swap, summons the clan elders and matchmaker to draw up a formal agreement, and secures the shops, estates, and dowry silver left by Yining's maternal grandfather. Three days after their wedding, Xiao Chengyu and his wife return to her family home and demand the dowry, but are refused. They then use a forged private seal to borrow 120,000 taels from the Gu family's money house. When their fraud is exposed, they reveal that the money is connected to the Northern Granary's military provisions. Gu Qingtang sends Manager Qi to investigate discreetly, while an authentic account book is slowly making its way into their hands from a former clerk of the Northern Granary.
