Oh I checked it and I think I understand what you meant lol I think you misunderstanded me what I'm saying is I think Rae's - not MC one's- soul swapped inside the Beatrice's body in that part MC means Beatrice knows about soul changing thing between Rae and her not between Bea and her (〜 ̄△ ̄)〜
Ummm...That's litterally what happened though? They specifically said that they swapped bodies LaMarquise
When I read that I saw it as Beatrice knew that Raeliana's soul got switched with the MC's soul and is not the same person. Cause there was no indication of Bea having Rae's soul, and if it's true, they kinda just slipped it in without even discussing it so that seems weird.
Im not pretty sure but what if Realiana's soul transfered to Beatrice's body?
