---edited--- it's definitely a MUST SEE drama. Seriously, probably the best one I've ever seen! First of all, the story. I can't say that it's really unique or absolutely marvelous, but I think it's quite good. As it's about music, about school band and such, it's easy to like it, nice to watch it and, of course, enjoy. It's not the first and not the last drama about music, however, the story is one of the better ones. It's not too predictable, but still easy to follow. You get into it from the very first moment and you kind of experience everything together with the main characters. Of course there were some things I didn't like (for example, Byung Hee's storyline) but, well, bad things make other ones seem good! As for acting I can't say if it's absolutely perfect as I'm not a judge or something, but it definitely makes that "rock band" feeling. I like the cast even though I haven't seen these actors in other dramas or films. But perhaps it's for the best as I can't compare their acting and I don't think of them as characters from other dramas. Anyway, what is really strange it's Kim Myung Soo's role! He seemed so silent and, you know, cute, nice and shy guy. But in this drama... well, he really is something! And I really do like this change! More or less all characters are really great as they're so different but similar at the same time. They make an amazing cast and definitely a wonderful band. Music in this drama is pretty nice. I even started to listen to "Eye Candy" performed songs and I love them! On the whole, I'm quite impressed by this drama and I like it much more than other Oh! Boy series drama (Flower Boy Ramyun Shop). And they didn't ruin the ending.(I was so happy when there were no "after 2 years scene!)
