I started this drama because of the theme. It's rare to watch those thematics on kdramas, so I was expecting a lot. The cast is good, and its characters too. But for Jun Ha/Ma Roo's character.. this guy gave me mixed feelings. He seemed a maniac sometimes, I loved him as much as I hated him. I wish the scriptwriters could be a bit more human and show some feelings too. He seemed to "go where the wind take him". However, on the contrary of other reviews here, I found this drama not long at all. I mean, truth that it was 30 episodes, but I have watched dramas with only 14 episodes that dragged the story a lot more. This just gets boring when we reach the 25th, 26th episode... I had to forbid myself from doing fast-forward (hehe) This is a good drama, at least for entertainment. I was a bit sad that they didn't develop the guy's sickness a bit more or show more romantic scenes... . They leave around the middle some loose tips, and don't really explain things sometimes, but it was good. If you are planning to watch this because of the matter of deafness I suggest you to check jdramas instead. This one was more focused on other things than it.
