This drama really made it as my most favorite Kdrama. It was really nice and very well put. It is something you really would have seen or experienced in an everyday-office-thing. The competition and struggles of one individual. Even those common traits you would have actually experienced or observed with your colleagues are shown here. While watching this drama, I was like, nodding and agreeing or sometimes reflecting that this kind of character represents either me or one of my colleagues. The good and the bad of an office environment is being reflected here. Even with the discrimination or bullying we usually experience, through educational attainment, seniority and or even gender differences. I was at first hesitant to watch it. I was expecting that this would be a sad story with a lot of exaggeration and dragging part. But no, I was so wrong. I was actually entertained. Even if there is no romance here, which is most common in kdramas, it still made it interesting and will make you stick to it to watch out for the next episodes. One thing I love about this drama is that the MC has really a strong spirit, and has a way in dealing with his situation, which is a technique he learned from GO. As for the music, I actually didn't have noticed it. I mean i was actually engrossed with story that I can't remember which music is being used. But since I really really liked this drama, I may have to watch it again and now pay attention to it. Lol
