You have written a story that has been touched by the heart but is renewed from time to time. When anyone first comes into our lives, they don't feel clean. But they and their relationship continue to have a never-ending relationship. We cannot even make a small difference in their continuation. If anyone came to this world, they must leave this world. That is the law of nature. It feels like your story is recreating beautiful past memories. I feel that the two of them were so close to you.
