The farmer's daughter Ran Qinghe was sold into her husband's family as a childbearing tool. After her husband protected her for three days, he was conscripted and sent off to war. Those three days of kindness won him five years of Qinghe's unwavering devotion to his family. But when her husband returned in triumph, he took advantage of her having no family to rely on, demoted her from wife to concubine, and married a new love. Qinghe used the family that had sold her to successfully divorce him. But when she tried to escape her bloodsucking family, she caught the eye of the powerful. With no other choice, she entered a ghost marriage to escape their harassment, only to unexpectedly become the matriarch of a marquis's household.
