In the third year of high school, influenced by his friend's strange illness, Su Nianfeng, who had no goal, decided to apply for medical school. Su Muyun seems to be an enemy of Su Nianfeng, but in fact she silently guards her and helps her realize her dream. The ideal university life started as scheduled, but the so-called truth revealed by Ouyang Xuejing, the school flower, upset everything and led Su Nianfeng to misunderstand Su Jia.

With the help of Le He Ouyang Yu, Su Nianfeng left Su Jia to live independently in order to find the truth, but Su Muyun fell in love with herself deeply.

A contract solved the "truth" of the car accident that year and cleared up the misunderstanding between the two families. With the unremitting pursuit of Su Muyun and the assistance of friends, Su Nianfeng finally put down her heart and came together with the boy who was a childhood friend.
