Lin Tingsong has always been quiet and reserved, yet she has silently loved Meng Jingyan, who is six years older than her, for many years. At Peking University's anniversary celebration, she leaps gracefully in a dance dress and unexpectedly catches Meng Jingyan's eye. He is generous and treats her exceptionally well, but their vastly different backgrounds and her past pain make her afraid to fall for him. When he is about to enter an arranged marriage, she resolutely turns away. After four years apart, both have grown and transformed, and after overcoming many obstacles, they finally run toward each other.
