Initially when i had seen the overview, i was hesitant as the main lead was an emotionless character. But man, as i progressed with the first episode, just after a few minutes i was hooked. The background music worked well for me. Jo seung woo did an excellent job portraying the role of a cold prosecutor. Even though he did not have any emotions, he was full of feel. Bae Doona was awesome as the lady detective. All the cast did an excellent job. Hope to see a second season with Bae Doona and Jo seung woo as the leads
