Maybe I would solve it with a punishment for grades, right in class or after school, because I am of the opinion that if a pupil can take the punishment home, it is not a punishment for him. Maybe I would let him apologize to the girls in front of the whole class, he would be a little humiliated himself, the question is whether it would not disrupt the relationships in the class even more. At least I would make an entry in the class book about the situation in the class, or I would inform the class teacher. I managed the Czech language practice relatively quickly.
