I wish thats not the case that the prince might realize that he just killed a innocent woman...
But I think that the story tells that the ex- now dead fiancé of the prince was switch place by the witch and the father of the dead fiance knows that it is not her daughter and was not sure if her daughter is alive or is the witch...
Either way... There must be some sort of a reson on why it happen

Right!? Until the end, there wasn't a single indication of her witch-blood. If I was in a life-or-death situation like that, I would hope that my latent powers will exhibit themselves -even if I never had conscious recognition of my ancestry. None of that happened for the fiance, other than the ambiguous tree protection. RIP
I really hate the prince. The girl clearly didn’t know she was a witch! It could have been some ancestry she had or a curse from the empress could have been placed on her to make the trees protect her.
I’m never letting this go you bastard prince. He’d better come to this horrible realization that he killed an innocent person for no good reason
