Perhaps the original Raeliana is now inside Beatrice, because she thought Beatrice would get together with Noah in the end, so she used dark magic or whatever that is called to transfer her soul. Maybe she is also a reincarnator or something like that. But it turned out (our) Raeliana ended up with Noah, so her plan went wrong and now she is trying to eliminate our Raeliana or go back to her own body.
Whatever is the case, I canāt wait for the next chapter. I hope it wonāt be another cliffhanger. I would die of curiosity if it continued to be a cliffhanger every chapter.
