I recommend this one to those who want to watch something different & One of a kind drama. This show is worth watching. Jo In Sung & Song hye kyo both of them done their role Perfectly. Specially Jo In Sung, He was Awesome in all kind of situation whether it was Sad or Happy, mesmerized by his acting. Also Song, who fit in her role , amazed to see her as blind person , how can someone be so perfect.❤???? Further, Storyline was Nice but it was annoying to see them as siblings till between the drama ????. Anyway Music was too good & suspense create eagerness for watching next episode. Loved this drama. One thing , Ending could be more beautiful...Worth Watching.
