Even though there are a ton of reviews, I'm reviewing this to bring it into the spot light again a year later. What a fantastic drama. I finished ep 24, and clicked right on ep 1 again to rewatch it, it was that outstanding. Between the smart, dark and intriguing storyline with it's smattering of light moments and the wonderful portrayals by the lead actors this was a pure hit. I was biased by the fact that the drama circled around serial killers, because that's a personal favorite for me. Add in the extreme personality of Simon Bo, and his almost alien innocence and it was a recipe for perfection. All 24 episodes kept me completely absorbed and interested. No skipping, no yawning and no looking away, not for a second. I can't recommend this drama enough. If you are looking for a feeler into C-Dramas, this is a great way to go, it even has a little romance, if you need it. Do yourself a favor and watch this drama.
