The plot line is good but the execution is not. Could have used the fantasy element in a much better way. I loved it very much at the beginning but later the drama became so repetitive. Whenever the King finds the culprit, they will find a way to escape or King won't have enough evidence. This annoying cycle remained same till the end. If you hate powerless and dumb ML, then this show is not for you. I'm okay with evil ministers with King finding tough to control or arrest, but here the antagonists weren't even worth for it.
Some of the supporting characters like Wal made the drama much better. And as for the FL, I loved Jin Se Yeon in the role of Eun Bo, but she was also annoying at times and definitely not a strong and independent girl as she was shown in the beginning of the drama.
Chemistry between the leads was good with great kiss scenes. I loved the acting very much and the OST is something to die for. Would have been a wonderful drama if it was short. This drama is definitely not a bad one for me, but there were annoying moments and some draggy parts which I would wish to skip.
