It's All the Second Grade's Fault

The beginning is very abrupt, and I have no idea what is going on. The strength of the protagonist and his gay friends is also very confusing. Sometimes they seem to be very strong, and sometimes they seem to be extremely weak (not referring to the weakness of the protagonist after the explosion, or sometimes saying that the monsters cannot break through the defense, and sometimes it feels very weak). It doesn't feel like I am reading a new book, but it feels like I am reading a new book, but it suddenly started from the middle after I wrote it, and I have no idea what I am talking about.
