This FL is so delusional . What I understand from og novel is that her husband didn't killed her and he always loved his wife, he went crazy after the death of his wife, when he died at end he said he wanted to be with his love, his love is his wife he never loved the white haired woman. FL is so naive and dumb and reach to conclusion very easily. And also that blonde haired maid cared about her a lot but she see them as enemies. And isn't she the author why don't she know any of the details and act so clueless
