In the misty rain alley in the south of the Yangtze River, Yun Zhi, a lonely embroiderer, and Chi Mu, a tea merchant in the capital, met by chance and fell in love with each other. A sudden change in fate forced him to return to Beijing hastily. During the years of separation, the two looked at each other across the mountain and suffered from lovesickness. A serious illness broke the barrier, and he went to the south of the Yangtze River to atone for his sins and stay together, giving up prosperity to stay with her for the rest of his life. With embroidery as a source of warmth and tea as a companion, a slow love that is gentle, healing, sweet and sad is staged.
