This drama has an intriguing although not new premise. It centers on how people can go through life with blinders on, pursuing their own happiness without sparing much thought on how others around them are faring. The show also explores how people cope when a loved one dies and offers a unique insight by illustrating this concept from the point of view of the "dead" person as well.
I especially loved the idea that you can be given an opportunity to set your affairs in order after you die, so that the people you leave behind find some peace and comfort.

The cast is quite well rounded. Standout performances came from Jung Il Woo in the character of the "Scheduler" and Jo Hyun Jae in the character of Han Kang. Lee Yon Won and Nam Gyu Ri were competent in their portrayal of Song Yi Kyung and Shin Ji Hyun. I appreciated the bond that eventually developed between these two women and how they helped and supported each other in their quest for justice, peace and ultimately happiness.

The other cast members are ok although I found Bae Soo Bin's character Kang Min Ho to be one dimensional, his facial expression doesn't change much from one emotion to the next. Similarly, Seo Ji Hye's constant wide eyed stare became monotonous very quickly.
The cast is underwhelming, with the exception of Jung Il Woo and Jo Hyun Jae, the acting was not dynamic and felt as though it was at 70% instead of at 100%, it felt mundane.

The story itself is good and it is well acted, however I would say it lacked that something extra, that indefinable quality that takes a drama from ok to excellent.
I quite liked the ending of the drama, it made a lot of sense as it didn't give an overly conclusive picture of the characters' futures.

The show could have done well with fewer episodes, like 16.

The music is good.

Overall score is 7.5 out of 10
