The drama, the casts, the plots are just simply amazing. Even though, the beginning can be a bit confusing (or is it just me), it's intriguing and catching that you will feel you're on the edge of your seat. The episodes aren't many but that's enough - simple but thrilling. You won't find yourself bored or do anything else aside from getting your eyes fixed on the screen. The OSTs are also nice! (Fav will be "break up")!
