This drama is one of the best written dramas I have seen, and the proformances from the actors involved was incredible. If you like simple dramas where you always know what's going to happen then this might not be the drama for you. I found it deeply thought-provoking and exciting for the point of veiw of somebody intressed in how the mind works. If you're intrested in psychology then watch this, it really makes you think about criminality and why people become criminals. On top of that, this story isn't just about murder, each character has a backstory which makes them more realistic as characters. Which is why I think that the writing is wonderful. If you like to connect with characters and care when something bad happens to them, then this is a good drama for you. As I fell in love with all the characters and I was almost shouting at the screen at points because of it. The background music fits perfectly, and I found myself wanting to buy the soundtrack straight after watching it. The only negative points about the drama, is that a) it's too short, only 8 episodes is not enough, so it's all over too quickly. And b) Once you've seen it the suspense is ruined because you know what happens. However I feel like rewatching it because of the acting and characters. On a bonus point there is also great cinematography in this drama, it's shot in a beautiful location!
