Overall this is a nice drama to watch.
The story is nice. About power, greed, friendship, betrayal, love, sacrifice, united.
Most cast may be not experience or famous actor/actress but still not bad act from everyone.
What make me continue to watch is...
1. to know what is the ending of the three love triangle between Sui, Sun Deok and Chiang.
2. If the father will be reunited with his two lost childrens.
3. who is the actual killer/bad guy.

This is so far the best Korean drama I watched.
What I see in this drama is Responsibility, Hope, True Love, Greed, Revenge and Forgiveness.
The story made me wants to keep watching and keep follow the progress of the story.
The chemistry between the lead actor and actress was superb. Great match!

Do watch to find out what happened!
