When you watch this drama you can't stop. Personaly I can't and I don't want to stop it, is not like other drama it's so weird strange and taping. This drama make me crazy, sad and happy. When I finish it I couldn't watch directly an other drama. Like we say in french "Une oeuvre d'art"!!! And the casting: I really love Sung Joon and Lee Soo Hyuk! Just one think PERFECT ! I reaaly recommended it. Sorry for my broken english
