Rewatch value is definitely 10!!! I've watched this like 3 times already and EVERYTHING ABOUT IT IS JUST PERFECT!!! My other favorite dramas start off boring and gets better but this drama started off so good you won't be able to stop watching. From the OSTs to the actors everything was just PERRRRFECT!!!!! Ji Sung is one big hottie and the plot is so...!!!!! GREAT!!!! It's not really saddd but really touching and left me in a lot of tears.. ALSO THIS DRAMA IS HILARRRRRIOUSS! That's what I absolutely love about it <3 It's melodramatic with a twist of laughter! Can't express enough how great this drama is and this might sound silly but this drama makes me want to have multiple personality disorder too! >_____________<
