You know, the protagonist has practically become an INCEL, even though he is surrounded by beautiful girls, he doesn't do anything, the story shows why he became someone... someone... so boring... don't get me wrong, the protagonist it's boring, but the girls in the work are interesting, including the protagonist's boss at the corporation where he works, I don't see how to "save" this guy from "eternal virginity" (no, he's not a virgin, it was figuratively), on the one hand this is spoiler, but you have to know what you're getting into, not even a practically naked girl calling the protagonist to have sex with her could do anything +18 with her, he basically ignored it... Anyway, his look bothers a little, but it makes sense for the proposal of the novel, but still, military service would do wonders for the main character.
My grade for each category (where 10 is the maximum grade):
Graphics: 10;
History: 8;
Character Development: 9;
Plot: 8.5;
Verdict: It's worth giving it a try.
Note: If I could I would give a 4.5 for the work because despite the protagonist being boring, other things make up for it, but as it doesn't, for rounding reasons, then the rating will be 5 stars.
Note (2): I don't speak English fluently, so the text may contain connotation errors.
