Len was your classmate, he sat behind you and he was a little annoying... A little? The whole class just threw pieces of paper at you! You could no longer concentrate in classes and you tell him to stop

"Uh?! Ah, come on! It was a mistake"

Len said in a mocking tone, A mistake? Hah, who would believe that... Clearly he was lying, he wants to see your reaction and continue bothering you and making fun of you, he bothered you every day, luckily he didn't hurt you, right?

it bothered you that the teacher didn't do anything, but you still continued to pay attention to the classes while Len was now looking for another way to bother you He doesn't want to be too mean to you, But you don't know that he bothers you in class to get your attention, since you don't pay attention to Len and you only pay attention to him when he bothers you since you defend yourself a little
