Ayuan version
A Yuan turned into a ghost. She thought she was going to be reincarnated. She didn't want to be a human being. She wanted to be the clouds, the rain, the wind. Pluto told her that there was a person who came into the world for her, but because of her in vain death, that person was still waiting for her. She needed to bring him back. As long as his happiness level was enough, the person would come back, and she would be able to choose where she wanted to be reincarnated. She agreed to the deal.
Hanqi version
Because A Yuan violated the law of heaven and secretly helped mortals, heaven demoted her to the mortal world and made her experience the sufferings of the world. I couldn't bear it, so I also entered the world. After I entered the world, I had no memory, but I was born with yin and yang eyes and I could see ghosts. There was a little girl who made me inexplicably happy when I first saw her, but she was a ghost, so what, I could protect her.
