In Shanghai in 1935, Shen Qingru, the daughter of a Suzhou embroidery family, stepped into the foreign market to investigate the truth behind her father's disappearance, and met the seemingly cynical banker Lu Jingchen on a narrow road. When the embroidery workshop crisis encounters a financial conspiracy, and the confession of the same month encounters an identity reveal, two cautious hearts gradually get closer in the flames of war. From the cafe on Xiafei Road to the smoke of Waibaidu Bridge, from the moonlight in Suzhou gardens to the gunfire in Sihang Warehouse, they made a promise with a song "Tuberose": If they cannot live together, they must die together in the morning light of the Huangpu River.
