Karma turns into a monster if he’s in love and around the person he loves. The king liked the MC a bit and the rose bloomed a little. He reminded himself not to like her if he wants to remain human. So it sounds like he is the same as Karma, but the only problem with that is the king turns into a monster even if the heroine romances the prince. Though that’s one of two possible endings, the "bad" ending. The MC doesn’t seem to know anything about the rose, so either she didn’t start or complete his route, or there’s something else going on. This should be interesting. I just hope we don’t see too many similarities.

Oh, that's right. It has been a while since I played CP so I forgot the details of his curse. Then, would that mean that Irene is mistaken about the king's situation and will be surprised by him turning into a monster when he falls in love instead instead? I think he is a dragon in the cover (not going to check), so you do have a point.
i think the king's curse is the same as Karma's from Cinderella Phenomenon.
