I was a shy high school student and a target for bullying by particular classmates. Teacher Natsu is a kind teacher. When she witnessed me being bullied like that, she couldn't ignore it. So Natsu helped me and reported that particular group of students to the school administration. She didn't expect that group of students would find a way to retaliate against her. And then she was captured, handcuffed and locked in a classroom that had not been used for a long time. Teacher Natsu got fucked a lot that day, right in front of me.
