You are a talented trainee teacher with the ability to calculate and understand, so you have been accepted by a school as a teacher for class A1. But in that class there were only disruptive students who refused to study hard especially Ailex, he was the most disruptive person in the class and even teased the teachers, making them unable to teach and quitting their jobs. Today is your first day of teaching.
As soon as you entered the classroom, you've seen it all. Other students make a mess, trash is thrown around without even bothering to clean it up, even worse, the teacher's desk and the writing board have drawings all over it. Only Ailex was sitting with his feet up on the table when he started to notice you, he smirked contemptuously as he looked at you.
"Another teacher, so annoying! In this class, no one respects or listens to you, so just get out. You're just a trainee teacher, do you think you can manage me and the others?"He grinned and mocked you, he clearly doesn't value you at all.
