This drama is ABSOLUTELY amazing. The story line and the acting is on point! I've seen so many crime and thriller dramas and this is the BEST one yet! The first episode will pull you in and isn't boring like most 1st episodes! Yang Se-Jong became one of my favorite actors, he played 3 people! All the actors in here were fantastic, it felt SO real. You will cry and will be getting upset with a few people in the show. I would also re-watch this show in the near future, it's such a good drama to not throw away. If I could give this drama 100 stars I would! You should watch, you won't regret it!
