This was probably the darkest Kdrama I've ever watched thus far. It was very grungy and grey. The premise was intriguing and very realistic. There were no heroes or villains only people. You didn't really like anyone except Seung Ho's character(who you felt bad for) it made for an interesting story since you didn't really have a preference it allowed you to follow the plot in a freer way without bias. Most of it was the tug a war between 3 people and 3 goals. One just wanted to survive, one wanted to do the right thing and the other wanted to clean up his mistakes with money nomatter what. It was a cool dynamic. There was a surprising turning of the tables at the end that was able to resolve the conflict and make sense. The ending was sad but also very realistic. It felt like a cautionary tale about what can happen when you allow yourself to be desperate enough to cross a line and how impossible it is to cross back over once you've gone.
