I was super excited to watch this drama because of the cast and trailer, but it was different than expected. The first five minutes of the drama was completely different from the rest of the show. I had expected more action and other people to be chosen on the roulette, but it was only focused on one person. Not to mention, it felt like he couldn't be killed LOL I definitely thought he would die after two stabs to the chest, but he somehow recovered in no time. Even a stab to the neck didn't do anything to him. He honestly felt immortal. Similarly, Mr. Smile doesn't die even after getting shot, but they don't explain why. It definitely seemed like a vital injury, but he ended up recovering like nothing happened. I was also very confused by how they kept going back and forth to the past and present from different perspectives, and it felt like there were a lot of loose ends. I can't help but feel this could've been so much more
