This has a huge group of talented young people. If they are all truly playing the instruments and singing, then they deserve props for that. I'm not a big fan of high school dramas, but I have watched a few. This puts most of them to shame in the music department. The story is pretty typical for a high school drama...bullies, childhood traumas, first love,etc. However, it was directed like a musical and I enjoyed that. I can't post about the parts I liked, because we aren't supposed to post spoilers. Bummer!!! ;-) Ha Yeon Soo as Se Yi and Da Hee as NaNa were my favorites. However, I liked all the actors and I thought they all did an excellent job. The music is outstanding!!! You should watch this drama for that alone. I will probably rewatch this at some point. I recommend this drama for all ages.
