I'll give this drama a 10/10. I can't comment anything that much because I can't find a flaw in this drama . Everything's perfect. The story, plot, characters, actors/actress, scenes, chemistry and even the OSTs. The ending might not be that satisfying but overall this drama is good. The pace of the drama is not fast and you can really understand every episodes/scenes. All episode are worth it. This drama is worth it. I'll recommend this for you to watch. You will really love/like each episodes. They really gives justice to the characters they play and they act it perfectly. For me this drama is good and even though it has 21 episodes, I didn't even find one of it boring. ^-^
