This drama got my attention since it's very different from those I've seen. The twist and unexpected scenes will capture your attention definitely. If you like solving crime stories then you will enjoy this one. Some scenes to me was repetitive and it got a little boring, but it picks up towards the end again. So Ji Sub did an amazing job again. The main actress was alright, but I felt like she didn't really have anything to say except reconfirm what was already said by others.
