Zhao Linglong, a top student at Yunzhou University, was supposed to have a bright future, but on his wedding day, his fiancé escaped from the marriage. He was caught in a scandal. He had no choice but to return to his hometown, Lingnan Middle School, and took over the worst class in the school - Senior Grade 11. She thought she was just teaching a group of uneducated and rebellious teenagers, but soon she discovered that things were not that simple - the worst student in the class was actually the heir to a certain consortium, and he casually donated a building to the school. The seemingly fragile female student turned out to be a witness under special protection by the police and was kidnapped one after another. The identity of the new transfer student is a mystery, and the files are as clean as forgeries, but they always disappear late at night... What troubles her the most is the physical education teacher Li Yunqi who always comes to make meals - on the surface, he is a rough guy who can't even cook instant noodles, but secretly he can play parkour on the balcony of the sixth floor. "Teacher Zhao, I forgot my key again..." "Teacher Zhao, what is your WiFi password?" "Teacher Zhao, I don't know how to solve this math problem..."
