This crime drama exceeded my expectation. The twist and flow of the story was superb, not too hasty nor slow... its almost perfect to make you sit on your chair for the entire season.

what I realize from this series is that... Giving or granting psychopath - serial killer emotion and conscience is like both gift and curse... its worse than death and life imprisonment...

The dilemma and feelings toward the ends was so strong... his repentance and salvation... the ending was just right... but I was also wondering, death was too easy for his father and that secretary... those are the thing I'm not satisfied.
