The story is interesting and confusing at first. The storyline brought to the screen the awareness of Alzheimer's. This debilitating disease can burden families and some families put their parents in a nursing home never seeing them again. They figure if they don't remember them why to bother with them. Some families feel their parents died when Alzheimer's began. As I said, I was confused when I first watch this but I did come back to rewatch the episodes and I caught on. I love Han Ji Min and Nam Joo Hyuk, which were awesome. This is a sad and cute story and I hope one day there will be Alzheimer's cure.
