In the south of the Yangtze River in the Republic of China, it was misty and rainy. Shen Qingwu, a cold woman who came south from Peiping, opened two teahouses - Wangjiang Pavilion in the Jiangnan water town. She loves tea as much as her life, is obsessed with the misty rain in the south of the Yangtze River, and is even more fond of all kinds of cheongsam and oil-paper umbrellas. However, there is a deep scar hidden in her heart: she once fell in love with Gu Mingyuan, a wealthy businessman in Peking, but was ruthlessly abandoned due to a family marriage. Frustrated, she traveled far to the south of the Yangtze River, trying to soothe her pain amidst the fragrance of tea and the sound of rain.
Qin Yi, a young officer who was transferred from Peking to Jiangnan, was burdened with a family engagement but had no feelings for his fiancée Zhou Muchhen. His arrival broke Shen Qingwu's peaceful life. From the initial strangeness and alienation, the two gradually got closer in the fragrance of tea and rain and mist, and their hearts melted quietly in the mist and rain in the south of the Yangtze River.
However, the gears of fate never stop turning. Zhou Muchen's sudden visit revealed the undercurrent hidden under the calm surface. Shen Qingwu's past, Qin Yi's engagement, family conspiracy, and the shadow of war are intertwined into a complex web. In the fragrance of tea and the flames of war, can the two break through the shackles of the world and find each other's destination?
