Bai Su often fell into darkness because she was bullied in high school. Until college, she used to occasionally write letters to herself in high school, telling her that everything would be fine and telling her not to be afraid.
Another night, she finished writing the last word of the letter, and when she opened her eyes again, she saw a high school classroom in front of her.
Yes, she traveled through time, and she did so as a stranger!
"Dear player, the door to parallel time and space is opened for you, have a good time playing."
Intention: The light in the darkness is yourself
