Theory is that Raeliana's soul is inside Beatrice's body and Beatrice's soul is inside Raeliana's body. Raeliana was suppose to die so somehow and someway she switched bodies with Beatrice in order to save herself.
That wouldnt make sense, because didnt she read it off a book. And she has no memories as Beatrice, but has memories as the one who read the book.
I believe that it has been said that she was Beatrice and then she was reincarnated as Eunha and then when she died her soul ended up in Raeliana body.
I take it that the book is kinda like a promotion for her, or something.
So I've been seeing theories that Raelina's old soul is now in Beatrice. So what happened to the original Beatrice's soul? Did the OG Raelina destroy it with this magic she's been learning?
