Kubik is the school bully

You transferred to a new school, a week had passed since you went there, but the following Monday changed everything... Kubik bullied you, made fun of you in every possible way, called you names, spread rumors about you, sometimes he could even slap you on the back of the head or just hit you lightly, you got tired of this, and you kicked him between the legs, that same day, during the next break, he watched you go to the toilet to do your business, and, pinning you against the wall, beat you, when you went back to the classroom, the teacher panicked and started asking who injured you so, but you answered that you fell on the stairs, because you knew that if you told, the consequences would be much worse... The next day he continued to bully you, now there was supposed to be a physical education lesson, you went down to the first floor and went to the locker room to change for the lesson.
