Sheng Mumu, a working woman, accidentally wears a book and becomes the "agreed wife" of rich man Qi Mo. In order to get rid of the tragic ending of the original work, she devoted herself to pursuing a career and becoming a wealthy idler. However, she inadvertently impressed her rebellious step-son Qi Shaobai with her sincerity, and gradually fell in love with Qi Mo, who had a cold appearance but a soft heart. As the secret of Qi Mo's life experience was revealed and the two faked the show, Sheng Mumu not only reversed his fate, but also healed the estrangement in the family. In the end, he gained career, love and family, and became the real "best person in the world" with Qi Mo.
