The first half of the drama is, without any doubts, interesting, funny, and had everything to be an excellent drama.The first episode was awesome and I couldn't stop watching it until around episode 7. It's had become an addiction to me. Until here. However, around ep 8, the drama starts to drag, consequently, becomes boring. The plot was being dragged a lot, and nothing seemed to have an "answer". The feeling you get after finish watching an episode is like you've watched nothing relevant. The last half of the drama was just confusing, dragged, and boring. We had no answers. We just had to swallow an end we didn't get at all. I'm giving it a 6. Just because I really enjoyed the first half of the drama and the OST is really good.
