Ling Se, the eldest daughter of Ling Ji Cloth Shop, has always dreamed of leaving her family on her birthday to live a life of complete freedom where she doesn't have to marry or cater to others. However, her plans are thwarted when she unexpectedly encounters Xu Zilu, the wealthiest man in Linchun City. Not only does he outmaneuver her to acquire a shop she had long been eyeing, but he also deceives her into forming a contract marriage, binding them together against her will. Despite this, Ling Se’s kind-hearted and independent nature and innovative business acumen gradually earn Xu Zilu's admiration, and he begins to develop feelings for her. As this pair of bickering yet fond "frenemies" continue their interactions, a hidden crisis within the Xu family begins to surface.

Fortunately, Ling Se's cleverness and entrepreneurial spirit led to the creating of a series of unique products. On their journey to the capital to resolve the family crisis, Ling Se and Xu Zilu grow closer, supporting and trusting each other more deeply. Together, they ultimately secure the prestigious title of Imperial Merchant and embark on a new commercial adventure in the capital.
