STORY: I really loved the story, even though, it's a bit complicated, especially in the first episode, I had to rewatch some scenes to understand, also, you can tell by watching it, that the writer really put so much work and effort in it, so much sad feelings mixed with happy, and always wanting to know what's going to happen next, but in episode 14, the drama could have been ended, but I think that they prefered making it longer, afterwards, it's just like another short story, just to fill the gap till episode 16. ACTING/CAST: in my opinion,the acting was a breathtaking, the cast really fitted well in this drama, I mean Yoo In Na was so into the character, when crying, she was so good at it screaming and everything, my eyes were all opened at full when she is crying, such a great actress, also, Ga Deuk Hi was a masterpiece in this drama, she was so funny, and really did well at her role, Ji Hyun Woo was very good to be honest, but I really don't like him, he's so not a person that fitted as a main role, but his acting is not that bad. MUSIC: I admired the OST of this drama, really fitted with the scenes, although there's so much sad feelings in it, but I really loved it. REWATCH VALUE: I don't actually rewatch dramas, but for the ones who do, I'll put a 7, though it's watchable, you'll be bored in several episodes. OVERALL: at first I was going to put a 10, but then I changed it, 'cause even though I really enjoyed watching the drama, it's not that fabulous to put a 10, so a 9 will do. P/S: in my opinion, it's worth watching, but in your spare time.
