What happened??!!!!!

"Did you hear the rumors?"

"What kind of rumor?"

"The school is a new teacher. It looks like he took the exam recently and was accepted to teach at school."

"Do you already have a photo of him? Is he a famous person? "

"It is very rare to have a new teacher at school. Which class will he be the teacher of?"

"According to the rumors that I heard, the name teacher will teach in class 2 F-2"

"That class of retarded? Now that you've talked about it. I remember that the old teacher went on a trip and the substitute teacher didn't want to teach the class."

"Yes. I remember that too. I don't know why the school still maintains this class F, this class only has a retarded and stupid student. They are all a bunch of losers who think they're strong because they have a powerful clan supporting them"
