Sadly, this is not the case for this one. It's a sexual fantasy through and through and offers little to nothing other than a ridiculous premise and sexual encounter. It's almost hentai. While there are some attempts at world-building here and there, the genric ideas and writing, and the poor way they have been set up makes them out to be window dressing instead of any establishment of the world the characters are in. And the main character is as bland as humanly possible, an otaku of sorts who reluctantly falls into a series of sexual escapades and somehow gets out of situations with another girl to add to his harem. The way that the writer has made the girls enter this guy's harem is also written in the most illogical, poorly paced, and insipid manner as well (chapter 4 in particular is cringe).
Basically, this is hentai masquerading as manga. I am even trying to figure out if it can even be categorised as a 'manga' with all of the explicit sex it depicts in such titillating detail. I suppose this is another example of how sexual content is beginning to be normalised in the commercial manga industry. I'm not really against adult content, but I think that when there are other adult works out there that have better writing, and embrace their role as 'self-pleasure' material, what place is there for something like this? Also, I can't for the life of me figure out how this existed as a light novel first.
A version of this done much, much better is Isekai Meikyuu De Harem O. Slice of life is done pretty well, and the characters are pretty well written, with the writer properly characterising the girl's interior conflict and all that. Also, the protagonist's relationship with the girls is quite believable. There's more thought has been put into world-building, and pretty good action, and though the story lacks stakes and an end conflict, at the very least the pacing and well-delivered story beats make it a decent read.
