TV drama review "Our textbook"

I saw the TV drama series "Our textbook" which took up the bullying issue at junior highschool. One day, a schoolgirl died at the school. Nobody knew that she accidentally tumbled down the window at her classroom and died, or she killed herself by jumpping from the window. The drama proceed in the style of seeking the truth. There are few drama I am interested in this period. In the situation, this drama "Our textbook" is the only one I contantly watch every week. The line which the schoolgirl told her teacher in the drama captivated my heart, "Can I change the world?". A lot of meanigs are contained in this line. I would never answered this question if I were a teacher and asked it from my student. I'm sure that I can't forget the grown-up line from such an immature girl. In Japan, the bullying-linked suicide increased and become a subject to disscuss rately. I really want to tell them who bully someone that you can feel better by doing something they cheer up than bullying them.
