In late autumn in Hong Kong, at the Sotheby's auction preview, Lin Wan wore an old satin skirt and stood quietly beside Lu Jinchen, playing the role of "assistant" - a contractual identity wrapped in a gorgeous shell. Three years ago, the Lin family fell into decline, her father was seriously ill, and she was desperate. She signed that unequal contract, sacrificing her youth and dignity in exchange for Lu Jinchen's financial support, and turned her talent for treasure appraisal into the most useful tool in his hands. At the preview site, everyone was deceived by the fake Qianlong enamel porcelain bowl, but only Lin Wan, with her sharp eyes trained since childhood, was able to tell the truth and avoid millions of losses for Lu Jinchen. But this edge still resulted in his condescending alienation and contempt and humiliation from others. She was his shady contractual partner, a silent treasure appraisal tool at the auction house, but she never stopped struggling. From relying on survival to gradually emerging, Lin Wan relies on her treasure appraisal skills to break free from the prison of the contract step by step in the treacherous antiques and vanity fair. She lives her own life and makes the man who once despised her regret it.
