This drama is absolutely PHENOMENAL. Whether it be about the acting, the script, the characters. It gives justice to the genre, which is a rarity in media. What I absolutely adore is the portrayal the of sense of justice. It's procedure is corrupted most of the time but the concept is pure in the drama. Another thing to admire the most is the net of attachment of the characters, they are all somehow involved. The most highlighted part of the drama, is Shin Ha Kyun's acting. It gives you chills, i swear. Overall, this drama is a case study for best crime and procedural dramas.
