In the Sky of the Wind Dog Boys, the characters in the story are plump. There is a four-person "small gang" in Jie Fangbei Middle School, which consists of four students: Old Dog, Dalijiao, Mimi and Mouth. Tu Yun was nicknamed the old dog. His parents divorced and he grew up with his father who sold pork. He is a special student in physical education. Zhu Weijiao, nicknamed Dalijiao, is the only girl in this group. She opened a noodle restaurant at home. She liked old dogs since she was a child, and later became friends with Martin, a top student in transfer school. Mimi's real name is Ding Rongliang. Her parents are old and her family is average. But for his future life, her parents left her bank card and real estate license early, just in case. Mimi likes Chen Yuanyuan in her class and works hard again and again for love. Luo is a big mouth, his mother is a taxi driver, and his father has not been with him since childhood. After online dating, he matured and his father came back to reunite with them. Finally, he was admitted to an ideal university.

The four men and high flyers Enron and Martin, who transferred at the same time, changed from hostility to friendship. The rich girl came to the old dog's good friend Liu Wenqin safely. Brother Qin is a grassroots figure in Jie Fangbei Middle School. He dated Enron, but he was injured because he bought a gift for Enron, so he couldn't go to college. These teenagers walk in the wind in the innocent campus life and cruel reality, and then cherish each other's friendship and relatives around them.

Each of them has a story and has experienced growth. The old dog's father had a bad temper when he was young, so his wife left him. Now he is busy opening a pork stall every day and doesn't forget to help his neighbors. After his father died in a car accident, the old dog felt a deep fatherly love. The old dog attaches great importance to friendship, knowing that his favorite girls like Chingo safely, or trying to promote them. Finally, with the help of Enron, he was admitted to the College of Physical Education. Around the old dog, the story also describes the study life of others. Among them, the interaction between the rich girl Enron and the sports student Qin Ge ended because of the huge gap between them, which made these young people realize the cruelty of reality for the first time.

They are such a group of young, energetic, reckless and high-spirited teenagers. They formed a marathon team for the college entrance examination, participated in the New Year performance to express their love, participated in the super girl selection for self-confidence, let go of their love for the love of their friends, and dedicated their hearts to the people they like. Behind them, we can see different parents and their same love for their children. The whole drama is shrouded in love, full of sincere affection, friendship and love, which makes people move.
