There's not much to say about the plot because the title says it all. After marathoning it during a long weekend I can clearly state that it's one of a kind and so I believe it's one of those dramas that you either hate or love. I personally enjoyed how flawed the four leads were; made it seem more realistic than other stories I've seen. Lots of 10s because it was truly outstanding. I'm not sure I'd rewatch the whole thing though because it's 22 episodes long but I would definitely find my favorite scenes to have a good laugh again. You'll laugh a lot, you might cry and you will definitely want to choke a few characters but hey, it'll be a fun ride.
