I loved every part of this play. I'm not the biggest fan of trailers, but you can't miss this one. It was the best way to tell the story, in my opinion. Really interesting, but at the same time unexpected.I loved every part of this drama. There were a couple of twists and turns that were really great. And you really can't guess who Getal is no matter how hard you try. I like that this is a drama where you can love the bad ones as well. While I'm at the story, I really feel like the ending was something that hurt me a little bit, even though I don't think it's bad, but I still have hope for a second season. The actors were also great. Everyone did a great job, especially Professor Kwon and Michan. But what I really liked the most was the OST, it was just fantastic. Each piece fits into each other. Of the mysteries section, this drama deserves an excellent rating. And the worst part is that it has just 11 episodes, i needed more. All in all, it is such a great mystery antihero drama and everyone should watch it!
