Shinenkan writes these kinds of stories all the time where someone gets turned into a doll and likes it and finds love as a doll.
For those confused: pages 6-9 are from the Doll girl's perspective, how she sees the dolls and how, atleast in her mind, they interract with her. While pages 10-14 are how the rest of the world sees it, the dolls as just dolls, not moving on their own. Are the dolled girls dead now or are they still aware and trapped inside their transformed bodies is a good question, but atleast to the Doll girl, they are and love being with her, as her play things.
