This is not a zombie apocalypse drama but a slice of life story showing how people deal with each other in the midst of chaos. Influenced by the events of Covid-19, the drama somewhat delves into the problems society faces when having to deal with an unknown deadly disease, the balance between safety and individual liberties, and people's biases.

The show starts off with a virus putting people into a zombie-like state making them crave blood. The first two episodes are about the spread of the disease until the plot switches to the main characters getting quarantined in a massive apartment building with no access to the outside world. The story mostly focuses on the best and the worst of human nature showing various residents dealing with their own problems and human-made happenings around the building. This reminded me of the movie "Clue" where a group of strangers got stuck together trying to solve murder-mystery.

If you are looking for passionate romance, you won't find it here. Although, the two main characters eventually kiss and become a couple, the romance is very subtle and focuses more on how Yoon Sae Bom and Jung Yi Hyun treat and protect each other without the use of cheesy romantic cliches. There are no tropey moments of staring and forlorn glances. The characters are very mature. They are not afraid to be alone and have physical contact without awkwardness.

The biggest problem with the drama is pacing which slows down somewhere in the middle. This is not so much about the plot, but the setting never changing. Characters run around various locations around the building and do the same things in every episode. This makes the show a bit tedious to watch.

The best thing about the drama is Park Hyung Sik. He truly shines as a serious character proving that he can play something other than stereotypical semi-comedic heroes. Here, he is a badass cop and a total stud. I want to see more of him playing generals, kings, and other males in positions of authority.
