The novel tells the story of Ran Dongyang's growth and changes in college in the form of a diary, involving issues of love/friendship and family growth in youth. It explores the growing pains of a girl and her attitude towards love, and details the ambivalence of the girl's growth and her love story with Wu Mian. It is a continuation of the college years of the characters written by teacher Yang Hongying. Finally, I would like to pay tribute to my beloved writer Yang Hongying, thank you!
