Some unknown world, with swords and magic, and a man who will never die. No one knows where he came from or where he will go. People only know that he is immortal and has all-powerful means. If he wants, he can even control the entire world. But he was not interested. He just wanted to find a woman whose appearance, name, or existence she didn't know. People thought there was something wrong with him, and he actually thought so too, but he still needed to fulfill his promise. After all, this was an agreement with her.
He is like a rootless duckweed and a lonely traveler. Although he has witnessed the death of people who know each other and hate each other in the long river of time, he will still row a boat on the star river and wait for her quietly to realize her wish.
Purpose: Tell the story of two people who have known each other for three lifetimes and fallen in love for one lifetime.
