at first i was watching this because it was related to music and the lead actor was Sung Joon from lie to me but trust from there i was just watching it just because it was really good and captivating. i thought people wouldn't really watch it because it airs the same time as Dream high but it proved me wrong. judging by the trailer u definitely knew it was going to be about rock and probably a dark drama but yeah... it kinda is. however this wouldn't be drama if it didn't have sad or dark moments and truthfully it has more happy moments than sad. you'll see your self crying then just after awhile you'll be giggling and smiling because of that one particular character that lights up the drama's mood that makes you love the show more than you thought it would. in the end the actors, music, plot, and romance is daebak
