i watched this drama during my super boring time of my life... i got curious after i read the story line then got really interested after i watched the first episode and the boredom vanished right a way. and the reason i think is because it has a fantastic cast, humor, romance, mystery, thrill, comedy and a very effective drama that can cried your heart out. It's a must watched drama cause it has all the flavor of a good story of love, hatred, and sacrifice. enjoy it and spread the good reviews about this incredible Kdrama.. fighting!. :) p.s it's very addicting after you watched the first episode so prepare to be hungry for more of it.
