Gibran once said: "A person has two me, one is awake in the darkness, and the other is asleep in the light."
Xueyao seems to be a little different. Her soul is half asleep and half awake in the gap between darkness and light...
She lived in such a state of confusion for many years, until another person appeared and changed everything she was used to.
It wasn't until much later that she realized that he was a key in her life. He had inadvertently locked her memory, and then unlocked it after they reunited. Save or free her from being addicted to fate...
(The story seems to be somewhere between fantasy and romance, and it also seems to be a worldly novel. Of course, it may be nothing at all. Put it in the legend for the time being, and maybe as the story develops, you will gradually find its place)
