from what i remember, a reader from another world showed up and made a deal with the demon king so she could take over/switch souls with dahlia's body and become the protagonist in exchange for summoning him from the demon world so he can be in the regular world, not realizing that she is actually a golem that was created by frodium dad bcuz he missed mc's mom and that the body will die soon, and the mc and dahlia decided to let dahlia get her body taken over and move her soul to that other lady's body so she could live longer and have a normal body and regular life without wanting to serve her and have free will. she's now in another body as like an information gatherer and still friends with mc, now having fun exploring the demon seals or whatever that she used to collect, and the body snatcher is upset shes not the main character even tho she took dahlias body lol.
Thank you so much! So we basically have another "Lina" situation, but she's from another world
I guess I must've have missed a huge chunk of chapters with updates, what made Dahlia flip on her?? I thought they were friends was confused af trying to catch up
