Edit: I take what I said before back.  This latest chapter has made me lose a little more respect for this storyline and these characters.  I still think this series is (barely) readable, but I'm starting to get what others are saying.  Characters are really 2-dimensional, and the MC doesn't treat girls well enough sometimes.
I stand by my "if you're out of stuff to read, I guess you can read this one" review.  Note that this series is definitely NSFW, and is basically softcore hentai.
