Holy hell, this is an incredibly awkward story, even by modern Palcomix standards. Also, if they even have a copy editor, said copy editor needs to be fired. Adam-00 has more natural dialogue than this, and I'm pretty sure English isn't his first language. (I mean no insult to Adam-00 by this.)
Guys above just didn't understand that such turn of a story was taken from tank [Kabashima Akira] Watashi ga Hentai ni Natta Riyuu / Why I Became a Pervert, chapters called Dourui / The Same Kind
