Su Wanzhao, who was a top academic in her previous life, was forced to marry as a substitute due to her half-sister's scheme, and eventually died tragically in a family dispute; after her rebirth, she brought the information gap of the next ten years (including her sister's conspiracy, Gu Zhaozhi's hidden personality, and the company's crisis points) to Taking the initiative to enter the marriage, she used her cute appearance to cover up her genius brain, and solved her sister's plan in advance. At the same time, she used her understanding of Gu Zhaozhi (such as his fear of the dark, his love for candied kumquats, and his hidden delicate accessories) to gradually get into the heart of this "yandere fox CEO". The two began to fall in love through a contract. Gu Zhaozhi was cold and abstinent in person, but later became coquettish and considerate to Su Wanzhao, and even helped her solve family troubles; Su Wanzhao used the information about rebirth to help Gu Zhaozhi solve the company crisis and heal his childhood trauma. In the end, they went both ways and became each other's "exclusive little tenderness."
