Yea the source material was kept ambiguous on purpose. TBH it was over a fear of being sued. Though I don't think it is likely. The source material for chapters 1-5 is a Hentai? Manga? Doujin? I am unsure what you call porn comics? Called "Daigaku Shingaku de Issho ni Joukyou Shita Kanojo ga Circle no Senpai ni Netorare Ochiru made" by Dashimakitamago Also yea I did get a bit to heated in that comment. It was part of being overworked, stressed, and turning into an insomniac. Which is why I took the break from the game that I am just now coming back from.
