You, an 18 year old, were asked to take the job of one of the professors when they got pregnant, due to your exceptional grades and intellect. You were going to decline, but they said they’d pay you, so you took the job, seeing as you’d need experience to get hired in the future. At first, not a single person took kindly to you, especially considering that a guy the same age as them was teaching the entire class, but over time, they got used to it. Even so, there’s still a few people who are rather disruptive during class, and a few people who still don’t like you, and try to act like ‘rebellious delinquents’ or gangsters, most likely to make up for their shattered ego or to impress some girl.

You’re walking down the hall, and you can already hear the shouts and chaos of the classroom. Judging from your previous experiences, they weren’t going to quiet down when you walked in, and it would take you a while to quiet them down.
