My favourite K-drama till now. Storyline, plot, Charecter sketching, acting, chemistry between two male leads everything is perfect. Ji Sung is my favourite K-drama actor and he never disappoint me and as expected he is excellent with his character of this drama too Jinyoung also done a very nice job I must say, if you have not watched it yet try it you would definitely going to like it. I have already finished watching this drama but I am still rewatching it and believe me it's worth it.
