Do I recommend this drama:
For those who prefer light-hearted dramas, I do not recommend this as the drama.
For those who are considering to watch this, I do recommend watching them with tissues on hand.

Story:
Per Netflix introduction, is drama where made half-human, half-spirit by accident, a young man was employed by a company of grim reapers in the underworld to carry out special missions. These special missions are to go to the land of the living to prevent humans from committing suicides.

Suicide is a sensitive topic, so it did came as a surprise that a drama was released with that topic in mind. This 16 episodes drama were broken down into mini story arcs (typically one case every 1 to 2 episodes). As the topic is a heavy one, the drama included elements of fantasy (grim reapers which special mojo) and comedic moments (when it is appropriate).

While the drama was thought-provoking; I felt that there are parts lacking. Personally, I was hoping for the drama to explain or emphasize more on Choi Jun-Woong (by Rowoon). Given Netflix's introduction, I was under the impression that his involvement would be a whole lot more than what the drama eventually portrayed.

Acting:
The cast did an amazing job in this drama; and not just the main cast. Every single cast in the mini story arcs did a fantastic job in portraying the required feelings of the character, which made this drama unforgettable. I have never watched a drama that I teared every single episode.

Note:
If someone told me before I started watching this drama that the content would be such a heavy one , I might watch this drama in the first place.
However, after completing this series, it does make me remember the importance of appreciating the little things in life that makes me happy.
