This drama is the product of creative writing and imaginative minds altogether creating a masterpiece. The wit, the humor, the script, the poetry, the punchlines, the creative scenes, the characters, the acting, the different mindsets and perspectives of people from the sanest to the most mentally-challenged. The dark representation of fairy tale presented in a good and reasonable way.
A drama par excellence.
If there's one thing that disappointed me (a tiny bit), it's the sexual tension between the leads, which is pretty common in K-Dramas, anyway. Lol. But overall, this is one of the best dramas ever produced. Watch it!
