nothing special.
oh there is, in other ddrama the villain end up in jail, in here they live a happy life more happy than the goblin withhout worry and the goblin will help if they meet trouble.

the only good thing about this is the actor/actress, the places and music...as for the story pretty much the same like other k-drama with the villain actually always near ml, the villain forgiven, the villain not regret what they have done, a dark human nature unnfulfilled without resentment just because from all the bad thing there is a little goood thing. the 1st couple cannot have a normal relationship even after all the trouble but the 2nd couple can have relationship with better enviroment and clear mind like they have not done a thing wrong just like that.

at the end this show is like watching top moment in social media, they are addicting because cute/the music good/the dances good/what the person doing interesting but there is no story in it, if there is! it is just a story to make the moment connectng in natural way.
