Reborn Swap Bride in the 70s

In a prior life, an industrious woman laboured alongside a modest husband who eventually attained civic prominence, only to be murdered out of spite by her envious cousin whose wealthy husband went bankrupt. Awakening in the past, she discovers that her scheming cousin has stolen her former betrothal.

Unbothered by the swap, she accepts an arranged union with the struggling aristocrat instead. Through diligence and sharp resourcefulness, she turns a marriage of convenience into genuine devotion, breathing vibrant new prosperity into the husband's declining family business.
