One of the best crime drama i have watched.
I like the pace of the plot and i must say the scriptwriter is really good at building emotions and subtle relationship details among the casts.

It wasn't said out loud but Cha Jae-hwan and Lee Joong Yeop both likes Eugene. Cha Jae-hwan's disappointment that Eugene did not feel anything for him was revealed three times, once when he was alone with Eugene at the park and second time when Eugene invited him to a western dinner at the restaurant and third time when his mum commented that Lee Joong Yeop and Eugene makes a lovely couple., and Cha Jae Hwan facial expression just shows his range of emotions.
Amazing.

Claudia Kim is such a sophisticated actress. She is so different from the current pool of Korean actress.
Now wonder she can make it to overseas productions.

One thing to note is, i really hope the screen writer has done a better job in portraying the role of a Criminal Profiler. Maybe more research has to be done. Kim Nam Gil in 'Through the darkness' portrayed more strength as a Criminal Profiler. The interrogation scene between Eugene and Lee Joong Yeop would have been more impactful if the questions asked were more specific. It was abit all over the place. That didn't do justice to the critical role of a Criminal Profiler.

I wish they could have develop the kinship between Lee Joong Yeop and Kim Hyo Kyeong. Their relationship should have been very important but it was not developed well. It doesn't make me feel sad that Hyo Kyeon died. They should not have included a sister in the story if they were not ready to develop that relationship. I mean, imagine how will Lee Joong Yeop would feel if he knows that he has a sister?! He was yearning for a family.
