Of all the Korean Drama, this is a drama that YOU'LL NEVER KNOW WHAT WILL HAPPEN NEXT. Because of this, you will be attached and eager to know what is the next episode. Salute to the writer, Lee Kyung-hee, this is one of the best story ever. Also, this is the 1st drama of Song Joong Ki that i've watched. What can I say? Bravo! Wow! Fantastic! This man is really talented. And good looking too... Both Moon Chae-won and Park Si-yeon, are great on their roles too. Another reason why i love this drama is because of the character of each casts. The anger and the love that they feel is really undeniable. No doubt that this drama ranked NUMBER ONE in its timeslot for eight consecutive weeks until its finale. And no doubt that Song Joong Ki won three times for Top Excellence Award.
