The first 5 episodes keeps me going but after that I felt like it's boring, but I just want to solve it so I kept watching it until the end of episode. What attracted me is Oh Ha Na's style. The storyline is quite unique but they keep blabbering until the end, so when it comes to last episode, I just had no reaction. I came here because Kyuhyun sang for soundtrack and it's great (Kyuhyun, as always). You don't need to rewatch it, waste your time.
