I now have a very scary inference, the protagonist is schizophrenic, he continues to go to the mental hospital every day, but mistakenly believes that he has a second chance in school, which can be inferred from the fact that he constantly throws away overly bizarre imaginations and returns to reality. In the fall, MAYA, who had never appeared before, suddenly appeared, and was extremely fond of fur balls. Could it be that his symptoms have worsened and he mistook the cat for a girl? In fact, there is nothing, the protagonist is just crazy.
