Shen Wei entered into a family marriage and was directly engaged to Lu Yushen, the eldest son of Lu. She thought it was just an exchange of interests, but she gradually lost control after entering the Lu family. Her fiancé is distant and indifferent, but his eldest brother appears again and again in her most embarrassing moments: blocking her from business difficulties, secretly supporting her design career, and even crossing boundaries to clear all resistance for her. She thought it was elder care, but gradually discovered that he had already accurately controlled the trajectory of her life. Until the truth came out - this engagement was a chess game he had made from the beginning, and she was the only variable out of control for him.
