K-drama at early episode are good and have some purpose story but after several episodes the story continues as if it has no purpose, for example Seok Ryu's illness which is only mentioned in 1 episode but is not continued even though she has cancer, and the continuation of the story is really boring. For those who want to watch, I think this is suitable to watch in episodes 1-5 or later because the rest of the story is very boring.
