I'm not sure if the storytelling isn't that great or if it's the manga adaptation.
-Suddenly has a mansion, fully equipped like the modern world.
-Has become an engineer/inventor and has an equipped workshop.
-Gets a full support staff but claims she is only a commoner... There was nothing mentioned about her relinquishing her noble status when she left.
-Now it looks like she has a spider robot, but why is she surprised? It was on her workbench last chapter so she's been building it. Maybe she didn't expect it to teleport to her. (Edit: small spoiler from start of next chapter; and of course it has an AI/personality)
-What happened with the magic ink?
-Why does it seem like the father suddenly has issues?
-Why is she casually implying the original girl died and her soul took over the body? It seems more like a near death experience made her remember parts of a past life. (Though I did question how she was alive after a week of no one taking care of her, getting no food or drink and laying in her own filth)
