Kinda reminds me of "The Unattainable Flower's Twisted Bloom", but in a more hard level.
Don't know why some people try to understand or hate the protahonist... its an ecchi/erotica manga. If you don't like it, search another one XDDD
At first it seemed a little weird, but now with more than 50 capters published is really one of a kind. BTW in november volume #1 will be translated and published in France.
