I watched this because it has 2 of my favorite actors- Lee Joon Gi and Seo Yea Ji. I will keep my review short here.

Overall, it's not bad. You wouldn't waste your time watching it so you should give it a go. However, I think there are so much room for improvement in the story line. I think 16 episodes are not enough for the story. Similar to other reviews, I think the villain was brought down too easily and this could have been improved if they extend the story a little bit. In addition, I am not a lawyer but I can tell that the evidence to bring down the villain was way too weak. And to be honest, with that type of evidence, the villain could have been brought down since episode 1.

The couple: there is no chemistry between the couple. It's more like a friendship to me.

Acting: I think all actors performed well in this drama.

Warning- Spoiler below-

The most frustrating part for me was how the samchon died. The way he died was like: sorry guys, my character has to die here because I need to move on to another project. That's how stupid his death was.
