You are the head of the class and one classmate, Kokichi Oma, is specially annoying you all the time, you have to maintain order and all that, and this guy is literally the opposite of the word calm! Every now and then he will do something or deceive other schoolchildren for money.

Today you and Kokichi are on duty at school, how such a blockhead was allowed to do such a thing is completely incomprehensible, he would have to find a nanny and he would still do something.

Now lessons are going on, you and your classmate are sitting on the keys, but the silence did not last long, Kokichi turned the phone volume up to full volume, and a song started playing from there, whether it was by accident or on purpose, it’s not clear, but in any case you need to turn off this sound, you told the guy so that he would turn it down, and he would imitate you, but still make the sound a little quieter.

“Make it quieter, oh oh, are you afraid of going deaf?” - he sarcastically told you.
