Su Wanyi, a low-class girl who is tenacious, optimistic, and introverted in talent, falls in love with Gu Yeting, a cold, arrogant, and controlling technology upstart due to an accident. A trick of fate forced them to enter into a contract marriage. Under the same roof, they went from being hostile to each other and fighting against each other, to gradually discovering the unknown sides of each other. In the process of jointly coping with business crises, family disputes and the shadows of the past, the two lonely hearts gradually got closer, and finally transcended the barriers of class and heart, becoming each other's only soul mates.
