Shen Anning is an orphan who must depend on others for shelter. Though gentle and delicate in appearance, she is clever and calculating, and she would rather die than become a concubine. Xiao Yu, the domineering and possessive heir of the Marquis of Zhenyuan, falls deeply in love with her but initially wants only to take her as a concubine. Determined to escape, Shen Anning carefully makes plans and repeatedly seeks a suitable husband, only for Xiao Yu to intercept every match out of jealousy. Household intrigues, framed accusations, and life-threatening dangers follow one after another. Amid their painful push and pull, the two gradually develop genuine feelings. Xiao Yu breaks through the barriers of social rank, tears up his marriage agreement with a high-ranking official's family, and defies all opposition. With the highest wedding honors befitting a marquis's heir, he sends eight bearers carrying a bridal sedan to marry Shen Anning as his one and only legal wife. The orphaned girl turns her fate around and finally wins the wholehearted devotion of one man.
