After losing his mother when he was young, Shen Qinghe only received a piece of dogtail grass from his mother. For ten years in the Shen family, she took this grass and lived under the cold eyes and abuse of her stepmother, becoming the most inconspicuous weed. Everyone thought she would marry her childhood sweetheart Gu Changyuan, but she calmly married into the Zhou family and married a taciturn concubine. Everyone was wrong - there was a knife hidden in the bones of this grass. With the power of the housekeeper in her hands, she turned over old accounts, investigated the shortfalls, and forced the poisonous woman in the first house into a desperate situation. After three years of dormancy, she worked step by step, ruining Aunt Liu's reputation, sending her stepmother into exile, and not a single person who owed her mother's blood debt escaped. But when Gu Changyuan returned from the border, she did not look back. The man digging the soil for her and making pear soup for her on the porch is her true destination in this life.
