The thing about the story is pretty much how the author's feeling during the time he drew and wrote the scenarios (In my opinion, I could be wrong). It doesn't follow a line which a normal story has. I consider it to be a borderline-hentai, slice of life manga. The story never seems to be progressing ( MC with the girls ). Considering these fact I'd give it a 5 for it's effort of keeping the *story* on track.
The only thing I give a better rating is the art. Even though not realistic ( big oppais and all ), was enjoyable
to read through. At some time repetitive but w/e who reads it for the story, only the art.
Like the story, the characters never seem to mature, always doing the same thing over and over (ecchi stuff) without changing really their thoughts. MC and his harem always think dirty and do "stuff" when left alone, like always. I think characters that are being added throughout the story are unnecessary fact that all character are proportionated same but "think" different.
The only thing that could be enjoyed for me was the art, really. If there's more chapters I wouldn't read more because of it's climax predictability in the chapter.
To conclude, I can't recommend this manga. Due to the fact it's story lacks real continuity and difference chapter from chapter. Even considering the author's effort to change the setting each time there's no real difference chapter-wise. Even though the art is enjoyable not seeing the "whole thing" can be boring when reading through. This manga focuses more on oppais than anything, not the full meal. If I were you I'd consider reading a hentai doujin at this point, not this manga. Anyways if you're an oppai guy or softcore guy you could enjoy reading this manga but for me it lacks a lot in story and character development so I'm not continuing reading after this chapter .
