In the late autumn of the twenty-fifth year of the Republic of China (1936), the sycamore leaves on Xiafei Road in Shanghai were all over the street corners. Su Manqing, the top singer of Bailofang, and Lin Yan, the watchmaker, met here for the first time. One is a cold beauty who hides illness and longing in the romance field, and the other is a restrained craftsman who comes to Shanghai from a foreign land to maintain a watch repair shop and poetry. The class gap and the undercurrent of the times cannot stop the bud of love. However, Su Manqing's tuberculosis worsened day by day, and the strong intervention of wealthy businessman Shen Xiaochen pushed this relationship to a desperate situation. In order to protect Lin Yanzhouquan, she signed a secret agreement with Shen Xiaochen, exchanging "marriage" for his safety and for her own medical expenses. In the spring of the twenty-seventh year of the Republic of China (1938), Su Manqing died of illness. The funeral was grand but cold. It wasn't until the war subsided that Lin Yan understood the truth in her will and relics: her "betrayal" was the deepest protection, and her cough was the unspoken concern. When the autumn wind picked up again, in the sobs of the Huangpu River, only the eternal regret he carried for the rest of his life was left.
