This drama is so different. I cant even categorize it into a genre. The story was filled with light moments as well as many dark ones. Its very slow paced which Im not fond of but thats just because Im an anxious person. Many things are slowly revealed throughout the drama. So its hard to wait patiently. BTW be prepared to bawl your eyes out in episode 19. the only other time ive ever cried watching a drama was with Stairway to Heaven so thats saying something. Alot of people on here complained about the ending. Ill admit when I got to the end of episode 19 I wanted to scream because I thought I wasted 19 hours on a drama with an ending that doesnt justify anything that happened the entire series. After I finished the last episode, I realized that it is not a storybook ending but you learn an important lesson about life and death. Something that is revealed in the last episode is mindblowing though so its worth watching. Acting was phenomenal by the entire cast. Even the villians were so good you feel sympathetic for them. The music was very whimsicle. It had a nice flow and went along great with the scenes. The OST is great too! Id rewatch this in a couple of years just because the story is sad and thatll give me time to forget most of the events that took place. Overall this drama is not your average drama but its something to watch and you will take something away from it.
