From the artist comment: "While the event was so traumatic for Otone-chan that she wasn't able to go outside anymore, when Mister leaves her alone enough, she stops being aware that she was raped, until she is able to resume her normal life. But she still dreams about it, and when Mister gets back in touch with her...😨 ...well, it doesn't matter when she's kept on a short leash as a pet.😅"
Well, that's all parts of the series for now. I gotta say, it really only got better over time, which is pretty dang impressive. Definitely gonna look out for more parts being released, would love to see more with this girl. When the awareness block gets released, this artist really doesn't pull any punches, I love it.
