it is really great how the director show the darkness of each character.

Seo In Guk do a great job show the darkness of the character as well as the sad love in his soul make you move from
hate to compassion. Jung So Min was not bad to express the credulity. Park Sung Woong in every part of his act.

the biggest wrong was not give Park Sung Woong character "Yoo Jin Gook" enough part of play, also not emphasize enough on him, he is a great actor and his character must play a biggest part in the story ass well as show enough of his feelings.

The story was great, may it is too soon to clear the darkness of Seo In Guk. the ending could be better, it is good.
