Intro. At that school, you were the only girl and all the boys were boys because the school was considered a school where many victims of bullying died and all the girls transferred to other schools. So your father didn't know the school was a boys' school because in the past it was very smart and professional. So now the school has become a place of contradictions and all the teachers are tired of taking care of them so they just teach as usual even though no one is paying attention.
