> Sae Bom & Yi Hyun's fight for Happiness and Humanity when stupidity is scarier than the vicious virus.

Zombie dramas are not uncommon but this ain't your run of the mill Zombie drama ; it is a mere reflection of covid pandemic/epidemic.
It is a zombie themed drama that pour slice of life scenarios into it. It has a great opening that is linked to our current pandemic situation. This drama started by how people overcome and get used to the virus and continued on their daily life.

The basic concept of Happiness (해피니스)is apocalypse and we are having more of it these days, no? But what makes this drama stand out is a different approach of showcasing human behaviour during crisis, more than the apocalyptic situation. Yes, that's how you have to perceive and watch the entire thing keeping that in your mind. Otherwise you gonna hate this drama if you have come here to see thrilling monster apocalyptic consequences, utter dystopia and plenty of gore elements or people smashing zombie brains left and right.
Infact the only headshot we love will be of the [spoiler] serial killer - andrew [/spoiler]

Yoon Sae Bom (Han Hyo Joo), an SOU cop is highly decisive, righteous and straightforward as a person. She never tolerates injustice and always ready to counter any challenging situation. Jung Yi Hyun (Park Hyung Sik) is violent crime detective who never fails to get to the root of any incident and is good at dealing with any kind of unforseen event. Han Tae Seok (Jo Woo Jin) an ex-military agent has the topmost hand as a pharmaceutical company executive who is aware of the origins of the virus and constantly strive to defeat the virus.

We have got many actors in the drama who are more or less familiar and are good at acting. My favorites are the the little girl , shopping mart teller , Lieutenant Lee Ji Soo and Na brother-sister; rest of them go east shit; who started as selfish brother and sister but they mad me laugh without even trying to [spoiler] the way he hid his sister behind when infected comes and the way he resisted to bite ; in the end becoming pivotal to the cure [/spoiler] ; which proves the point :

> Humanity is the biggest cure for any disease ...
resist not to harm the people even after infected takes a lot of will power and which is what produced antibodies as the virus couldn't incubate enough to infect the brain.

The entire piece is thrilling and awes you with its suspense at several points but it might not feel compelling which is okay because it's more important that you understand the underlying messages which the show wanted to convey. Overall, Happiness is a good drama which experimentally shows the social science P.O.V of human behavior and the underlying psychology. Please keep in mind that it's 10% apocalypse and 90% about demeanor of so called social animals, namely human beings. It's definitely worth the one time watch and I would surely recommend to give this a go, at least for Park Hyung Sik ; many said he widened after military service but his action and fights were very much improved compared to Strong Bong-soon.
