Su family heiress Su Qinghe concealed her family background to accompany Lu Chengxiao in building his career, but overworking to regulate her body caused her figure to drastically change. At a banquet, Lu Chengxiao confessed his true family status and chose to partner with Lin Man. Heartbroken, Su Qinghe tossed her bouquet and registered to partner with Jiang Yu, who was avoiding a family-arranged blind date. Later meeting by chance, Lu Chengxiao and Lin Man manufactured friction, while Jiang Yu silently guarded Su Qinghe throughout. Su Qinghe regulated her body to restore her original appearance, exposing at their wedding banquet that Lin Man had misappropriated support resources and fabricated her background. Recognizing her at this moment as the girl who saved him three years ago, the two worked with one heart to protect the family business, leading a fulfilling and happy life.
