For anyone reading this manga, I strongly recommend that you stop right now. It may have started as a mix of Ijiranaide, Nagatoro-san and Karakai Jouzu no Takagi-san, but from this point on, everything is going to change. The author isn’t going to preserve her purity — Sasha-chan is going to turn into a complete slut. The manga is going to become something totally different from what it was in the first 29 chapters. So here’s my warning from someone who read the rest and got completely traumatized. I was wrong. I thought the wild things Sasha-chan said were just her way of getting closer to the protagonist who liked hentai, but she actually does everything she talks about and everything she implies she does.
