Li Tiancheng, the heir to a corporate empire, falls in love at first sight with his employee, Qi Ziqiu. However, Li Tiancheng is already bound by a six-year engagement, while Qi Ziqiu is also on the verge of getting married. Torn between moral obligations and her own feelings, Qi Ziqiu finds herself irresistibly drawn to Li Tiancheng, whose personality and compatibility suit her far better. The two realize that what they share is not merely physical attraction, but a deeper connection between their souls—and perhaps a chance to break free from the wrong people. Caught between morality and emotion, they embark on a time-limited, seven-day romance in search of an emotional escape.
