It is a nice drama with amazing casts. I thought the story would be boring but I got hooked. At first, it was dragging for me, but later on, I found myself not wanting to stop watching it. We can see here that they had their own reasons for the crimes they've done but they are also regretting their actions. I loved the character development of the people close to Kim Je Hyeok. They all cared for each other like a family. I would want to watch it again but I think the ending lacked what the viewers expected the most. Watch it, and you'll know what I mean! :)
