Transparent

"Transparent" There are two kinds of transparency in the world: one is that no one sees you. One kind is that people you can see will eventually not be able to see you. A Wang has lived in a world that no one can see since he was born, until he met A Ying on the riverside - the girl who was also invisible, but could see him. They plant vegetables, watch the sunset, and count the stars, thinking that the days can go on like this forever. But Aying is immortal. She will live forever and he will grow old. The day he left, she held his hand from dusk to dawn. Later she searched for him for many years. Many, many years later, on a street corner in a strange city, she saw a man standing by the river. The wind blew his clothes. She walked over and stood behind him. He turned around and asked, "You... Can you see me?" She smiled. He doesn't remember his past life. But she remembers. She waited.
