Thank you! And I agree taking away the blade without any real offers of support is not a solution. It only makes the MC feel even more cornered/stuck between a rock and a hard place with no way to relieve the stress even a little. As for the PE teacher, I hope he learns that he has to handle things a lot differently.
I just really needed the teacher to apologize to him which was not shown and I don't think he did. Apolgizing would be the normal first reaction but he just looked at him and did nothing. He didn't even go up to him to help him or take him to the infirmary or sth. He also didn't tell the others to stop laughing. I know that maybe he's just a very stupid idiot but that doesn't justify it.

Since I can't reply to my own post I'll make a new one and say this here: I'm not a fan of the glasses guy. I know its an unpopular opinion but his victim blaming is common... and I'm not surprised. Also, I like the P.E. teacher simply because he isn't being malicious towards or victim blaming the MC. He's just clueless, and, yes, that includes about the fact that he is making things harder for the MC. I do have to point out, though, that if glasses guy hadn't stepped in, things might have turned out exactly how the P.E. teacher wanted them to.
