I shouldn't be writing the review after giving low ratings but I really need to let it all out!! First, story: The basic story was vague, like really really weak. I couldn't understand whats happening most of the time. It was the big ent. company blocking everything for Perseverance and you come to know the answer to 'WHY' in the last two episodes!! Character development is the thing that annoyed me the most. I'm BANA and ELF so I started this because of Jinyoung and Henry but I was so disappointed at how weak the characters were. Ray was like fake or something? He gave that kind of vibe and communication issues between the characters were horrible. They kept getting the misunderstandings regarding every second person and there comes a time when you are like: WHAT IS WRONG WITH YOU GUYS?! -_- Acting was ok, fine. Not many emotions except from Hyo Rin. Shi Yang's acting was good but then again his character ruined it for me -_- Music is the best best thing in this drama. Really awesome song covers. I loved and enjoyed almost all of them so 9 points from me on this! Rewatch value is low because believe me, I took more than two months to finish this! -_- I apologize to the fans of this drama!! I really wanted to enjoy this one but TT_TT
