This show definitely stands out for its unique theme. The story pacing was just the right amount, not too fast or dragged out. The use of children's fairy tales for the narration of plot and characters was beautifully done. Main as well as supporting character stories are well written especially the character development we see in all the characters. The actors did an amazing job, Oh jung se's acting as moon sang tae was really amazing to watch. The OST tracks are really beautiful. The show also has a very satisfying ending. Overall it's a very good show and will definitely recommend this show. The drawback according to me is that it has the cliché kdrama tropes without which it would have been truly unique.
