This story is mostly about women's sexual desires and the need to fullfill them. That's what the WHOLE story is about. This is a completely ecchi story with lots and lots of sex and attempt rape (the women being the rapists). If you aren't weak hearted then you might enjoy this manga. this story isn't anything like a normal high school experience though, some of it is just WAY out there.
However, when all the sex and ecchi scenes are taken out, there is a romantic story going on underneath all of this, starting from protecting someone to actually developing feelings. Heartache and betrayal leads
up to the moment when you can finally see that you "love" someone.
