For the first section, I'll keep it spoiler-free!

The first thing that intrigued me about Happiness was the way the virus functioned. Despite the zombie-esque premise, the infected are alive. Once their episodes pass they return to themselves, they can think and feel and communicate. Despite having the same hunger and urges that your everyday zombie has, they're still people. And sure this isn't the only time this has been done in media, but in a genre oversaturated with dehumanized corpses, it provides us with a much lesser shown perspective. Humanizing the infected made the situation both hopeful and bleak as we're shown them in both their frenzied and calm states. But their living state doesn't necessarily grant them compassion from every character, and the lines between what is okay and what isn't start to blur.

To start from the beginning, Happiness is less a monster thriller and more an exploration into the different forms of happiness, what they mean to those who seek them, and what lengths those seekers will go to reach them. Yoon Sae Bom's motivation at the start of the series is to have her own home, a place that is entirely hers, after growing up never having her own space. She had a rough go of things when she was younger and is now desperate to take her first steps towards that long-sought goal, so much so that she even takes Jung Yi Hyun, a long-time friend, to be her fake husband in order to get the apartment that she wants. JYH, for his part, reached his lowest point in high school when an injury took his future in baseball away from him, and it was YSB who pulled him out of his thoughts and allowed him to think clearly.

But Happiness isn't just about these two characters. Over the 12-13h runtime, we get the stories and motivations of about a dozen other characters, each in pursuit of happiness of their own, be it in the form of money, companionship, lust or family. The pursuit of happiness isn't always a noble battle, and what means the world to one person could mean nothing to the next. In this way, the drama explores the darker sides of greed, envy and lust very thoroughly. Because of that, there are more characters you don't like than those you do, and even the ones you've enjoyed early on can infuriate you later. For me, that was the beauty of it. It felt very human, if exaggerated. Let's be honest, it can be a bit much. In around two weeks, we see people fall to newer and deeper depravities to get what they want. Desperation can do a lot, but the sheer number of people who break apart so quickly in this series is staggering. But, well, the pandemic showed us just how quickly panic can bring about stupidity.

So on one hand, we have a bunch of people infected with a rabies-like virus who still retain their humanity. On the other, we have a bunch of people with different beliefs, motivations and moral compasses all stuck in a building together. From cops and bickering siblings to murders and scammers, they either try to sway the rest to their side or try to determine who they should trust. At the end of the day, if they all stayed in their units and had appointed a few people to bring their food and water to them, then this story would have had half of the blood and death in it that it does. But we've all experienced quarantines and know how big of a hit they can take on mental health, even if there aren't zombie-like people trying to break into your building. And we all know those people who just won't follow the rules and stay indoors. Not everyone listens. Almost everyone is scheming. The entire story is a mess and I love that about it. I even love how angry it made me and how many times it sent me on tangents complaining about the characters. Because, for all of the annoyance it caused me, I liked how it actually felt like characters other than our leads were moving the plot along.

Spoilers ahead!

Happiness, like its concept, isn't perfect. Sometimes the leads made stupid or reckless decisions. Sometimes the other characters did, too. I can't really hold that against it, though, because humans by nature aren't very logical. We panic, or we're hasty, and we make bad choices. We mess up. It happens. Naturally, there were some things that I didn't like beyond that, as well. The first is the serial killer story that developed in the latter half of the series. While everyone could see what was going on with Andrew from a mile away, I did feel like his identity-stealing serial killer subplot felt a bit out of place and tacked on. They needed to up the stakes for the last few episodes to make it interesting, but suddenly bringing in a serial killer who doesn't have anything to do with the main conflict of the virus was a bit too left-field for my liking, even if their goal was to show that humans themselves are more dangerous than any monster. If they were going to add it then I wish they went deeper into his story and the plot surrounding him to make his story feel more grounded.

What really bothered me was what they did to Kim Se Hoon. From the very start of the drama, he was an interesting though very rarely seen character that I wanted to see explored more. He was a paranoid, doomsday-conspirator survivalist right out of the gate and I loved that about him. Despite his very radical beliefs and his concern over catching the virus, he was kind and considerate not only to our leads but to the other characters as well (even if under YSB coercion). He came down to place his vote on whether to kick Kim Seung Beom out of the building even when he didn't want to leave his apartment until the quarantine was lifted and shared his food, even considering to share it with the rest of the people living there despite not really wanting to. I really wanted to learn more about him and see him survive until the end, but instead, he's killed off-screen (though I believe there was a flashback later) and his body is dumped. Not only is he ultimately a tool in the Andrew subplot, but he's left forgotten until they need to use moving his body as an excuse for one last high-stakes conflict. They could have done more. I wish they did, but that's what we're left with.

I think Happiness could have done well with either an extra episode to properly resolve everything, or a restructuring of the plot to allow more time in the end. It felt too rushed and there were a lot of loose ends that needed to be tied. We saw that Han Tae Seok's wife survived, but what about their child? It never showed the child being born or passing away despite being so heavily referenced in his scenes. We never had YSB visit her mother in the nursing home even though she voiced her regrets over not doing so before the quarantine. We don't know if Park Seo Yoon's father made it out (they mentioned severe symptoms for him, but we never saw the family fully reunited), or if Kim Jeong Gook was okay after being treated or if his wife was okay (we can assume, but we don't see him after recovery and we never see his wife despite, again, mentioning her throughout the whole story). These are just the ones that stand out in my mind, but there are probably other loose ends left hanging. Dramas can't always close off every little thing, but even having ten minutes at the end of the episode to show these characters finally reunited with their families would have been a nice way to close things off.

So yes, I have a lot of gripes. But even with all of that, which would normally bump this drama down to an 8, I have to give it a 9. It may not have closed off as nicely as I would have liked, but the relationship between YSB and JYH was beautiful. From episode 1 their chemistry was great, I loved their dialogue and their scenes together were my favourite, but by the end, I really felt how much they meant to each other. JYH was willing to do everything to protect YSB. They trusted each other unconditionally, and the only time we ever see someone talk an infected down from an episode is between them. It isn't just them, though. The old lady, despite being one of the first ones infected, never has an episode (to our knowledge). Her husband is harsh with his words and bickers and complains, but after finding out that she's been infected, he quarantines with her in their apartment and stands guard outside the bedroom door at night to watch over her. He never leaves her, and she's never put in a situation stressful enough to attack. She has the willpower to control it the whole way through the drama. And even her son, one of the stupidest, most obnoxious characters, experiences character growth by the end. After abandoning his family when he found out that his mother was infected and stealing their food, he returns in the end and reconciles with them, and they wait there together for the soldiers to arrive after the quarantine is lifted. Another woman gains the courage to leave a man who clearly doesn't value her, and a brother and sister whose relationship was strained reconnect after almost losing one another.

So, okay, it's not perfect. I hate a lot of people in this. My quibbles are endless. But somehow this is still one of the dramas I enjoyed most this year, and I'm happy to have experienced it.
