A drama of TWISTS and TURNS! Definitely for those who love mind-boggling dramas and those who love to take guesses. While watching, you can't help but contemplate about this: "Are monsters created, or are humans born monsters?" This drama has a really unique plot. This would make you realize a lot of things about humans' real nature. It depicts how past events can greatly affect one's thinking and behavior. There are lot of unpredictable scenes. But on the later part, it might be kind of very confusing but it was sort of cleared up before the ending. It's very very unpredictable til the end. Brace for it! The cast were great. Their acting was sort of convincing. Each of them were suitable for their roles. Well, I must admit, there are lot of eye candies (kekeke) but they have REALLY performed a great job. *claps* Music suited the scenes, it added an extra effect to the thrill. Hmmm, rewatch value, I think, I wouldn't want to rewatch this (maybe after some years, I'll try) since the excitement and thrill would be lessened since I would know how everything would turn out... Definitely this is worth the watch... Must-see!
