Story: 9/10
A heartwarming, funny yet sad story about a man and a womam (kinda) in love. (what a suprise?)
The romance is a clear 10/10 for me. Kim Da Mis acting is superb and Choi Woo Shik also plays his role to perfection. The dialogues are very well written and not once did it feel like the characters words and actions were incoherent. Why a 9 then? More below.

Music & Audio: 9/10
Theres nearly nothing to criticize here. All songs perfectly fit and push the emotions to another level. It does sometimes feel like the mixing is not perfect, but I believe that is a personal preference. The only minor problem with the music is that all the songs resemble each other, and theres never a big style deviation. While its understandable, at one point in the series they couldve used a change in the musics pace as a stylistic element.
Kinda sad they didnt.

Acting: 10/10: just perfect

Camera&Editing: 10/10
The emotions the series intends to deliver are perfectly delivered through flawless camerawork and impressive but subtle editing.

-------
The only gripe I have with the Series is one of the Subplots. Feels a bit like Perrin from AWoT. It could have been a bit less, but its still okay.

Highly Recommended: 9.5/10
