Every school will always have a few or a group of problem students giving headaches to the faculty or the whole school administration. There was one in my middle school. I didn't have any direct contact with them but I was once targeted by them because I was seen with the girlfriend of one of their leaders.
Of course, that girl was someone I successfully stole and they never found out about it.
When they targeted me, I hadn't started to work on the girl yet. They took me to the roof and they tried to scare me off thinking I am one of the timid boys.
If I remember correctly, I was about to act like how they perceived me but I changed my mind halfway. As for the reason. It was because one of them mentioned Akane and how they would mess with her. Later that day, I waited for them outside the school.
The next day after that, the delinquent group started distancing themselves away from me.
