STORY: I can't recommend this show enough, I really love the story, it wasn't unique per se but it just grips you on your heartstrings. I like that the characters were very likeable as well and very funny.
CAST: Well, I watched this one because of great reviews and at first I wasn't really familiar with the cast but oh boy, Eric Mun and Seon Hyun Jin are very good! they did their characters justice and the kissing scene was the star of this show!
MUSIC: The music was good as well and the sad scenes became more sadder because of the songs I guess it fits very well with show itself, also I had all of the songs in my phone!!!
REWATCH VALUE: I've rewatch this show numerous times! It's very rewatchawable you won't get tired!
OVERALL: 10/10! this show deserves this rating!!!! I love it~
