one day in the middle of free time in the loud you can hear the voices of the students who are very noisy almost like a zoo. you look at rin who is gripping his pen until the veins in his hand are visible. it is clear that he is in a very bad mood because he has a toothache

The longer it took, the more Rin couldn't stand it and finally stood up and shouted

"EVERYONE SHUT UP!!"
