The embarrassing young boy Jiao Yang has a secret wandering dream and a precious innocent heart.
Perhaps his best field is picking up things. He picked up a younger brother and a dog on a rainy night.
Jiao Yang named his younger brother March. March is so cute and inhumane, and her life experience is complicated and confusing. She is controlled by her brother and has an unusual desire to possess Jiao Yang.
The dog is a black Labrador dog named Duoduo, which comes from Qian Duoduo, Jiao Yang's most admired deskmate, because Jiao Yang sincerely hopes to get close to Duoduo, his great deskmate who has always ignored him.
This article tells a series of joyful youth stories about family, friendship and love between Jiao Yang, March, Qian Duoduo and classmates and friends around him.
The author swears with his toes that this story is really, really innocent! Purely! Pure! ——It must be true!
