There are a few things I don't understand, I mean what happend after she got into Sen's body? They practically hated her. She behaved ill towards everyone. The father kind of knew she wasn't the real daughter and abandoned her. Why does she want that life back? Is it just a plot hole because the author decided the twist too late? Or is she just delulu and crazy?
@Mimi well she was delusional since the beginning thinking she was Francif lady, if not how she that is older by years as Sen will be the original? ... as little psyco it doesn't matter how she looks they can recognize something is wrong with just with her behavior and I assume the crazy priest told her what to do to damage Francif family then that living as a delulu she just push the auto destruction bottom without knowing, because she aside of crazy is an idiot
