Likes:
* The way the writer/producers interpret well-known fairy tales into a darker version with the intention of motivating you to face the harsh reality head-on instead of daydreaming a happy ending.
* High degree of chemistry between the leads. Seo Ye Ji and Oh Jung Se were phenomenal! They shall receive an award for their outstanding performances!
* Supporting roles that acted so well - I was either rooting for the good ones or hating on the evil ones!
* Amazingly beautiful visuals.
* Tear-jerking subplots of the hospital patients.
* Indirectly educating audiences to be empathetic towards other people who seems to be different to you.

Dislikes:
* The little plot holes towards the end but nahhhh, it's forgiven.
