The story and setting is okay. All characters are well thought. The downside is that there were characters, issues and complications that was unable to put emphasis on. The writers started of great with giving each character a story but it wasn't emphasized. This could have given more chance for the series to grow and be recognized. The cast are great too. Although their characters have been used for almost all musical drama that I've watched, all of them was able to perform their roles well. The music sound great. It created a bit of thump in my heart but just for that moment. I mean it didn't give me the feel of researching their OST. All in all, compared to heartstrings, you're beautiful, dream high and shut up flower boy band, this drama is lacking. BUT its worth the try :)
