The story described in this novel is the farthest distance in the world. It is not that I stand in front of you but you don't know that I love you, but the distance between life and death. Life and death are irreparable pain and there is no turning point. This farthest distance is one of the clues of this novel. When writing this novel, I paid great attention to the sense of picture. I look forward to your witness.
The last innocence of human nature, our persistence in love when we were young, thinking that we can be happy by holding on to memories, loving each other clearly, but not promising anything, just because we can't fulfill it, so that the other person can let go, but we don't know that from the moment we fall in love, we are destined to fill the pain in the other person's heart with a lifetime of love. Even if we know there is no ending, we must keep hope, even if the other person repeatedly emphasizes that today's hope will only make the future more desperate, we will not hesitate to sacrifice ourselves. This is the main theme of this novel.
