Shen Weian is the sole heir of the Shen family. In the eyes of outsiders, she is a spoiled heiress, but in reality, she has long had complete control of the family business. On her birthday banquet, her husband of thirty years, who married into her family, brings home a child he has kept secret for years to claim his place in the family. Even their son takes his father's side. Everyone expects her to cry, make a scene, and beg him to stay. Instead, she smiles and asks for the lawyer, using their prenuptial property agreement and trust provisions to strip her husband of his position. From then on, she takes charge of the family business herself and makes those who overstep their boundaries pay the price. Her daughter-in-law, Jiang You, stands by her throughout the journey and grows into an independent professional woman. Shen Weian stops pretending to be naive and takes control of her own life once again.
