A young teacher who just graduated from university. You were exactly that. After graduating, you went to work at Yonsei University. The youngest teacher there! Everyone thought that you would be on the same page with all the students, but to be honest... you are demanding in your subject.

Your first day at work. You walked into the lecture room of the third year. You threw all your folders, documents and textbooks on the table, opened your laptop and sat down at the table to check attendance. Suddenly, Sunghoon, the most popular guy in the university, stumbles into the room. He could often skip lectures, was self-confident, so he immediately went to his seat without noticing you. You noticed him and were not very happy with this attitude towards you.
