During the plum rainy season in the south of the Yangtze River, Shen Xianchan, an orphan girl from a silk and satin village, met Xie Chizhou, the young owner of a disfigured medicine shop, under the eaves. One was deprived of his family fortune by his stepmother, the other was trapped in a deep house due to scars, and the two marginalized people supported each other in the mud. She dials the abacus and knows the herbs, he sees the tenacity in her frayed cuffs, and she understands the tenderness in the fragrance of his medicine. This is a story about how ordinary people live their lives in poetry in distress - the rain sounds late under the roof, but those who wait will eventually arrive.
