Well, in fanfiction, his classmates' reactions can vary widely. There are those who are his friends and they would be supportive. They might cover for him when he has to run off to be Spider - Man. On the other hand, there could be classmates who are envious. They might spread rumors about him or try to expose his secrets just out of spite or envy. And then there are the classmates who are just indifferent. They don't really care about Peter's secret life and just see him as an ordinary classmate most of the time.
His classmates would probably be very concerned. Some might immediately run to get the teacher or the school nurse. Others might gather around Peter, asking if he was okay and trying to comfort him.
However, there might also be some who are a bit skeptical. They could worry that he might misinterpret some of the fanfiction or use ideas from it in a way that the original writers don't like. But overall, I think most would be positive as long as he respects the fanfiction world.
The characters in Harry Potter would likely be very shocked at first. Hermione would probably start researching immediately to figure out what Michael Myers is.

Michael Miles did take off his mask in the Moonlight series. In a certain scene, when he faced Jie Mei, he did not stab her with the knife in his hand. Instead, he took off his mask and revealed his true face that no one else knew. He also shed tears. This was a rare scene that showed his human side. However, even though he took off his mask, he did not change his evil identity and continued to pursue Jie Mei. Therefore, Michael Miles taking off his mask did not change his nature.
