Shen Nanxu, the concubine of the Shen family, was cast aside by the world because of her plump figure. Shen Wanrong, her sister-in-law, stole her fiancé Xie Linfeng and forced her to marry Xiao Mozhi, the chief minister of the cabinet who was rumored to be "severely injured, disabled and inhumane". I thought it was just a change of prison, but I didn't expect that this forced marriage would actually become each other's salvation. The two went from awkward trials to growing feelings for each other. She discovered the truth behind his pretending to be weak and dormant, and he saw her tenacity despite her low self-esteem. A court conspiracy involved the two of them in life-and-death danger. She used her body as a bait to help him solve the major treason case of the second prince, and was granted the title of Princess Anshan. In the end, the couple had a heart-to-heart relationship and stayed in love together.
