A genius profiler Lee Hyun (Seo In Guk) returns to South Korea after an anonymous email about a criminal case triggers memories of his childhood trauma. One of his team members, Detective Cha Ji An (Jang Nara) has “stalked” him since childhood and is suspicious of him as her life was also turned upside down by the same criminal. As they investigate the case, they realize that the truth is not far from the unresolved mysteries of their past.

This drama is a good combination if you want a crime drama shrouded with intriguing mysteries around genius characters, without a lot of stress. It was suspenseful at times, but the romance and quirky sound effects lightens the mood. Personally, I did not like the music, but it's not a big deal as I'm invested already. The storytelling was great, as in character's backstories were established well, without revealing too much and as the story goes, it fleshes out the complexity of each character. The twists was paced equally, keeping the momentum alive to the end.

Beyond the crime-thriller aspect, I love how it covers friendships, family love and such a heartwarming brotherhood. The other highlight is Park Bo Gum's character, I've only seen him in romantic roles, and here he was very complex and his expressiveness was outstanding! Seo In Guk and Jang Nara were great too, good chemistry and good teamwork. all in all, great story and acting. Another one I recommend!
