I don't remember if I finished reading this one as I didn't use a normal manga site, but the plot was exactly as I expected and this story was just more proof of why I hate male-centered single-sex societies. Mangakas seem to think that if a society is mostly women then men will be praised as idols and gifts and while possibly still sex-objects they'll be praised as such, but they also seem to think that if a society is mostly men then women will be hunted down like sex toys and abused and threatened, etc. Hate that.
But the weird twist or whatever from which this manga gets it's title was boring and not worth it. The premise to start seemed to be basically trying to get the protagonist to pretend to be a doll so her presence won't cause mass chaos causing her to be raped to death. But (spoilers!) if I remember correctly there was something about his sex doll crying in the end, implying that either there are more women than was previously thought or that dolls can become sentient. THAT is what this story should've been about in my opinion!
