I did not understand the writer in this drama. It is hard to write about death. It is a hard subject for people to like. For me it was hard to see because it hit to close to home and I preferred to think of happy times then sad. Many of these characters story was about dealing with the death of a love one. Either a mom with cancer, Or a death by accident, or Alzheimer's which is a slow death of a person but for the love one is hard when they are not recognize, they feel they have die in their parents eyes. To the parent that love one does not exist. The last 4 episode made no sense to me. He pushes her away because he does not want to hurt her but torture her trying to break up. I also did not like the Idea that he would vanish because his life was extended. this is not realistic. death is death. I would have preferred that he was told when he was going to die and then he would have die by accident. The psychology of this drama especially the ending was to harsh to take. We watch movies and shows to forget the sadness that we live everyday. The acting was great by all the characters.
