So thats why her eyes are blackish gray instead of purple...I mean I kinda expected that she is the real daughter but I didnt expect her og eyes are purple...I thought its because her parents havent seen her in years that they must have mistaken her eye color for a purple..but I guess I was wrong on that part...so if the MC finally gets her og body back, does that mean the curse on her body will be erased? Like completely? So in this case, that boy is also alive once he receives his body back or is it too late? WHO EVEN IS THE MAIN MALE LEAD? I have a feeling its either the son of the duke who can smell curses or the boy who was also cursed like MC...SPOIL ME WHO THE MAIN MALE LEAD IS.
