Light Novel Volume 4.5/Summary

Below is the long summary of volume 4.5 of the You-Zitsu light novel series.

Prologue
The narrator talks about "Sazae-san syndrome", a term about the depressive feeling one can have when realising the next day is Monday, and links the similarity to how the students feel near the end of summer vacation. The narrator disagrees with the feeling as they see the years in school are essentially the only time one is able to freely do what they want, as they will have to spend most of the rest of their life working until retirement after that. The narrator points out how many students have failed to appreciate being a student until later on in their life.
