Review Detail of Aerovium in I Only Wanted A Class In The Apocalypse

At first, it was cool and I had some fun with it. I got sucked in and ended up reading up to chapter 88 in one sitting. It slowly felt like things were becoming more messy overtime. Every time the MC would meet a girl I feel like his personality would change. By chapter 88 he is saying things like 'Damn girl!' and calling his summons 'little boys'. There were also things like there being 15000 screened people and apparently all but 12 betrayed humanity. I wont say it's horrible, but it definitely developed into what I'd call a junk food novel. I deleted and reposted my review twice, once for scoring issues and once because I forgot to spoiler tag it, I am not good with the review system.
