In the late autumn of Shanghai, the sycamore leaves fell all over the long streets. Jasmine met Shen Yubai for the first time at the engagement banquet of the family marriage. He was the leader of the Shen Group, with a sharp wrist and indifferent eyes. However, when he was raising a glass, his fingertips inadvertently ran across the back of her hand, leaving a slightly cool touch. This marriage, which began with profit, has been entangled with ulterior secrets from the beginning: Jasmine's father suffered a sudden stroke, and the company's equity was mysteriously transferred; Shen Yubai's mother died in an "accident" many years ago, and the clues lead to the Mo family; and Lu Jingchen, the bamboo horse who has been guarding Jasmine, hides his ambition to subvert everything under his gentle appearance. When the dusty diary was opened, when a familiar gasp came from the late-night phone call, and when Shen Yubai held up an umbrella for her in the heavy rain, Jasmine suddenly couldn't tell - in this love filled with calculations, who is the chess piece and who is the chess player? Hidden behind the thick fog deep in the Chonglou is not only the grievances between two generations, but also the sincerity that everyone dares not express.
