The 8-year-old Lin Nuonuo is a little prodigy who loves to study, following her senior brother Jiang Chen to audit courses on the university campus. Quirky and eccentric, she speaks fluent Henan dialect, effortlessly cracking difficult problems in class and instantly attracting everyone's attention. At first, her classmates all thought she was just a little kid joining in on the fun. The cold and stubborn Jiang Chen originally planned to look after this little girl, but time and again he was touched by Nuonuo's intelligence and kindness, silently turning into her exclusive guardian. Nuonuo often hangs out in the study rooms and libraries, helping senior students sort out their ideas, and touches everyone around her with her childhood innocence and enthusiasm.
