I personally enjoy apocalyptic dramas, so I was naturally drawn to Happiness as I read the synopsis. I love the new view that was put on an apocalyptic world. It draws many parallels to the covid-19 pandemic, which was really refreshing to see. The stories make you realize the evils of the human heart and all the things that people struggle through. It also gives you the experience of the lengths people will go through for themselves. The main characters amazed me, I love Park Hyun-sik, and he is one of the main reasons why I started watching in general, but I stayed for Han Hyo-joo. Her character gave such a refreshing image to the main female lead. I always hated female leads that were weak or damsel's in distress, needing a man to save her. Han Hyo-joo's character is the opposite, not only can she hold her own, she does what she wants and can to protect those that she loves, even if she does not show it. It was also nice to see a strong couple, their promises to stay safe, but their strength as individuals to hold their own was impressive. They did not need to save each other because they only had to be there for each other.

Even though the drama was mostly held inside an apartment building, the building's people definitely represented the evils of the world. There were murderers, frauds, scammers, rich, poor, and a whole variety of people just packed into a building struggling to maintain its structure. It was pretty infuriating, seeing that the main leads could not do anything because they had to follow the law and rules given to them. But overall, I really enjoyed this drama.

I do think that the ending was rushed. I think it was initially supposed to be 16 episodes, but it was somehow shortened to 12. That was disappointing, as I would have loved to see the main leads live out their lives in happiness after the last scene in the show.
