You will see Bea's soul would always be extinguished and the goddess realized this late, it is advisable to read chapter 125 and 67 to understand the following better: The goddess used the Korean lady since it was compatible with the little that was left of the Beatrice's soul so she united both souls so that Bea would not die, if not that she would live with a new soul, that is, the protagonist can be considered to be what remains of Bea's soul but itself is the Korean at the same time, a new Beatrice.
In any case, it was this "new" Beatrice who stayed with Noah in the original story ............... so the Korean lady read her future in herself ...... ................. I know this is very creepy
Edit: In the original story she had her memories of Bea intact but due to the change of bodies she remembers those of the Korean lady, current Bea knows it and that is why she does not consider her her friend since her soul changed, although she is only one excuse since she already hated Bea for a long time because she felt inferior to her and completely bolted when she learned that they were in a book and that Bea would be the heroine while she was the extra who dies, the witch offered her the She changed and she accepts after hearing about Beatrice's future where she stays with Noah .......
Look, I don't hate Og Rae for wanting to change his life or fight for it, my hatred comes from how damn hypocritical I turn out to be "I kill innocent people who wanted to live but I have it justified because I want to live and change my fate ", aghh I know she felt bad for her life but that does not justify her cruel acts, besides the duke decides who she will marry, not her, she wants to be free and be loved but she does not have to return that love and gratitude, if she wants to, she can kill them, but not because she is a "victim", damn, that it was useful that she lived if she only did it to do evil to many people who had nothing to do with her "misfortune"
