I mainly watched this as I was recommended this and I was interested in seeing IU's acting and also seeing Park Yoo Na portraying another character! I was not disappointed apart from the kdrama True Beauty, this has to be one of the best dramas I've seen from TVN.

Acting
The cast did so well with portraying their characters to the point I forgot this was all fictional. The crying scenes felt so real to the point I shedded tears of happiness and sadness towards the final episode. IU and Jin Goo truly have some chemistry and they didn't have to have many intimate or sexual scenes to show that.

Soundtrack/OST
Amazing! The osts are absolutely beautiful it has to be one of my favourites to listen to! They do an amazing job capturing the atmosphere whether it's to create sadness or suspense.

Plot/Storyline
The writers did incredible! From the beginning to the end of the kdrama, I was intrigued of what would happen next with each episode, the writers definitely know how to keep the reader on their toes. The comedy was great too! I couldn't help laughing at some points.

Cinematography and Special FX
The Cinematography and Special FX is something I'll never forget about this drama. The makeup artists did incredible with makeup to create a ghostly look on the actors, it gave me goosebumps! Plus the editing is incredible, it definitely adds to the ghostly/supernatural atmosphere. Also IU's stylist needs to get a raise! I couldn't stop admiring at her outfits throughout the whole drama, all of them were gorgeous.
