Su Wanxing was adopted by the Su family since childhood, but was always treated as an "outsider". In order to save the face of the Su family, she was forced to marry Shen Yizhou, the CEO of the Shen family, for Su Manqi. On their wedding night, Shen Yizhou dropped the warning "Don't try to interfere in my life" and moved to the company. Su Wanxing endured it silently, hiding his identity while working part-time as a designer in his free time. At a business reception, Su Wanxing accidentally helped Shen Yizhou resolve a cooperation crisis, and Shen Yizhou began to notice this "different" wife. After that, he went home frequently and would take the initiative to bring breakfast to Su Wanxing. He even subconsciously defended Su Wanxing when Su Manqi suddenly returned to China to provoke her. Su Wanxing was both excited and panicked, fearing that she would lose everything if the secret was revealed. Just when Shen Yizhou was about to express his feelings to Su Wanxing, Su Manqi deliberately exposed the truth about the "substitute marriage". Shen Yizhou was furious, and the two fell into a cold war. But after calming down, Shen Yizhou discovered that he had fallen in love with Su Wanxing, not the identity of "Su Manqi". He began to chase his wife crazily, helped Su Wanxing escape from the control of the Su family, and supported her design career. In the end, the two resolved their misunderstandings, faced the pressure of the top circle together, and gained love and growth.
