The story, plotwise, sounds like something I wrote when I was 11. It's just so baffling bad and is nonsensical. The plot is so, I can't even explain it, it's non-existent. The only reason they try to push the story "forward" is to get to the next ecchi scene. The obstacles the MC must overcome is the most underhyped and easily solved roadblocks in manga history. An obstacle that would normally take 3 chapters to overcome in any well flushed out manga is easily overcome in a single panel, it's nonsensical to say the least. If you are looking for ecchi and some nice artwork you'll find some enjoyment, if you're looking for anything else you might as well leave.
There are quite a few plotholes and characters that the mangaka just seemed to have forgotten about which really makes you confused as to why they were even mentioned in the first place.
For example in Chapter 26 (Not spoiling anything just some nonsensical things)
they suddenly mention a guy who hasn't appeared for the last 20 chapters saying that he can't be trusted, all of a sudden they are mentioning names and events that they didn't show, but simply happen like the audience is supposed to know what they are talking about. They suddenly say that xxxxx is actually a very important person for blah blah blah, and all you can think to yourself is, "wait a minute, who the fuck is xxxxx? I have absolutely no idea who this character is and you're just bringing it up out of nowhere?"
With most bad mangas there are frequently pages you have to stop and re-read many times just to figure out what they're talking about or how some progression happened, this is one of those mangas. As I don't speak Japanese it might not actually be the mangaka's fault, rather the translator and proofreaders, but it doesn't matter either way because no matter who the fault is on, it's still confusing as hell.
