There are some flaws with Happiness, like the ending for example. Not only was it sad because of the victims of the serial killer, but I had wished to see him prosecuted because of it. Instead there wasn't much on that. I also wished to see more of the general and his wife, but you only saw him give the antibodies to her. The ending wasn't bad because of that, because all of it was pretty much wrapped up in the end. You saw the general have a happy ending, although it didn't go into too much detail. In the end, Sae-Bom realizes her love for Yi-Hyun and calls him her home. Happiness did not focus on the outbreak, as it is pretty much contained to the apartment, but rather Sae-Bom and Yi-Hyun. The outbreak was a plot device for her to realize how he was her home. That was the reason I loved this show. :-)
