First of all, sorry for making this in English. I don't know any Japanese, but I loved this story so much that I had to sign up and make a review for it. The world the author built is fantastic! It's so well thought out and deeply planned that all the nuances are not only extremely creative, but also incredibly realistic of a world that would be like this.
A lot of chastity reversal stories are almost always the same, and never really push it to the limit of just how much the world would be different because of it. EXCEPT for this story! I was obsessed when I first started reading it, and hunted the original down to this site, which is why I found such a great site despite it being a different language.
The author should really be proud of this work and his ability, as this story even has world wide fans. Not to mention, I spend all of my time reading stories, and this is hands down my favorite. It's 10 times better than 2nd place as well. I don't know why this story doesn't have even higher ratings. I think I just found an amazing writer before he became famous is all! Haha.
My only regret is that the original woman who saved the main character wasn't somehow revived, or that the people that killed her didn't listen or take the hint and revive and imprison her for him somehow. I get that the character needed to be removed so that he could enter this society the way he did and learn everything without the old lady being a major part of the story, but I still wish she would come back because of how much of a medical expert she was. He could gather the finest and brightest rejects around the globe, even ones that got falsely or accurately accused of a 'crime' against a boy.
Anyways, love the work, and can't wait for the next chapter!
