I watched this show because I liked the acting of Kim Woo BIn in the heirs. I am so impressed by his acting and honestly, no one could have done justice to his role in this drama other than him. Also, the fact that he is diagnosed in his real life makes it so heartwrenching. I wish him good health and quick comeback again. Just make sure you have enough tissues with you while watching this drama because you are going to cry more than a bucket.
