Am I the only one that thinks that the story was full of holes right from the beginning? I mean where is the demon? So he was so against the witch meeting the FL, but when she met the prince it was fine? How come she didn't have a single guard on that day? How did the witch even meet the crown prince? If the demon was still there, how come he didn't tell her that necklace had something wrong with it? How come she didn't know when she is a witch and how come she was killing people with her hands while being controlled when she is a WITCH, she uses magic...... How come she is also good with a sword? The demon cared so much in the past but then disappeared and didn't care anymore? Also how come she was willing to give her heart to the FL but not to the crown prince, the one she loved? It doesn't make sense... And whole story was so many cliches... The guy has nothing original about him, they never make him human, also why would she have to wear a dress for him to blush? So she's only pretty in a dress? How come no one tried to investigate what happened to the witch? How come they didn't find the FL there, or how come she was at the same place? The palace wouldn't have stayed the same... Just so many holes, I don't know if the manhwas was just badly made and maybe the novel explains the story better, but this is just such a mess...
