Story: Considering it was a short mini-drama, I think it's a super simple story which could be better, but somehow it was okay to see. This mini-drama is okay to see if you don't have anything else better to see. It's about a bad boy who's job is making success the karaoke is working in. And everyday a girl appears at 0AM, and after somedays which the girl doesn't appear the boy starts to worry and look forward her. Acting/Cast: The acting sucks a bit... THe girl, Seo Min Ji, made a great job, but Nam Tae Hyun's perfomance was the worst I had seen until now. I think he has to improve more before make a drama, so maybe he can keep going on mini-dramas or making cameos in another dramas. Music: I think the music could be better, but not as bas as another dramas. Rewatch Value: I would consider to see this serie again, because it was boring. Overall: Even if it wasn't the best mini-drama I had seen until now, I think it was a perfect mini-drama to see without subtitles (or korean subtitles) to improve my Korean. So I recommend you to see this one if tou want to improve your Korean skills.
