C The female professor and the rich son of the second year college student
On Nan Qingwan's first day as a substitute teacher, he met Lu Yu who was late. When Nan Qingwan saw that he was about to be late, he stepped on the accelerator and fell into the school parking space. Lu Yu, who parked his motorcycle, couldn't help but take a second look and saw Nan Qingwan striding towards the senior high school teaching building. Lu Yu followed slowly and walked to the door of his classroom. Lu Yu stopped and looked at the class card "High School 3 (Class 10)" and thought it was interesting. Nan Qing walked into the classroom as the class bell rang.
The noisy classroom fell silent for a moment, and the students all looked at this woman who was dressed simply in a shirt, trousers, and white sneakers, but with a cool appearance, walking towards the podium. "My name is Nan Qingwan, and I will be your English teacher this month." After speaking, he picked up the chalk and wrote his name on the blackboard. Just as he was writing, Lu Yu made a report at the door and walked towards his seat. Nan Qingwan put down the chalk and clapped his hands, "You will be punished for being late."
