Oh Gosh, this was so good. The storyline has its ups and down but it is really good. I will be rewatching it again soon. Lee Jon Suk (Park Chang Ho), what can I say about this actor? He takes a character and he will perform it to the fullest. What he did in this drama is take someone who is weak and made him strong. Life can do that to anyone. Park Chang Ho (Go Mi Ho) This is a wife that stood by her husband's side from school to wife. Her character already had that strong personality and she rode with it. What a great drama. I thank the writers who brought awareness to cancer and how the environment you live in can cause cancer. I applaud the writers. Activism at its best.
