After reading twice i finally understood what happenned. the real raelianna is in beatrice body because she want to be the heroine but unfortunatly someone took over her body and she is trying to get rid of the current raeliana believing she could win. (⊙…⊙ ).
She is such a creep becoming someone else is not gonna change her. the way she scratch the book made me understandヾ(☆▽☆)

I think the soul has to leave the body in order to posses said body. So yes, Beatrice is gone. In her body is raeliana, but since raeliana’s Original body wasn’t dead, but bereft of a soul, eunwha’s soul was sent into it. So the only question remaining, is who sent eunwha into the book And effectively into raeliana’s body? I could hazard a guess but I’m still uncertain.
I am confusion. Somebody pls explain.
