Surgeon Jiang Wan accidentally traveled to the 1970s and became a 200-pound fat man infamous for arranging marriages. When she opened her eyes, she was sleeping next to the cold-faced Lu Jingchuan. In order to clear her reputation and regain her dream of becoming a doctor, she decided to lose weight and prepare for the college entrance examination. In the process of pretending to be a loving couple with Lu Jingchuan and facing difficulties from all sides, the two went from being suspicious of each other to gradually trusting each other. Jiang Wan uses modern wisdom to outsmart the green tea nurse and resolve neighborhood conflicts, while Lu Jingchuan changes from being cold and distant to being affectionately protective. In the end, Jiang Wan successfully lost weight and was admitted to college. The two of them faked it, gained careers, love and family, and opened a new chapter for them.
