Random otaku theory huh?
While with just that i'd have justification to snub your comment as idiocy, i'll humor you for a while and actually try to explain in simple terms so that even someone like you can understand...
You see there is a very big difference between hentai and porn in general... In porn all you're after and all you can get is instant gratification and nothing else, while in hentai depending on the genre and the sort of content (whatever it is a game, a visual novel, etc, etc) you can have other elements that might be just as important or even more so than the sexual elements like the art, the music, the style of H-scenes, the style of presentation, and a million other details that might or might not have anything to do with sexual themes but together form a singular whole and thus something that unlike porn can actually be seen as a work of art.
There i said it... Hentai can be and to many people is ART, because it isn't something catering to people who just want mindless sexual gratification without even an ounce of deviation or innovation of the tried and true formula (most of the time anyway). If you can't understand something like that, than maybe you should just go back to pornhub or whatever, no offense of course...
As for this particular game, as i said previously it might seem like there is nothing more to it than just the H-content, but that is just because of it being so early in development and any other sort of content like the actual story or the lore is something that will come later on...
