Parallel world. There will be some short stories created around the characters in Agents of Time, and there may be regrets.
Do you have any regrets? Do you think there are parallel worlds in this world? A world opposite to reality. There are many regrets in the world we live in. It may be in real life or it may be the tragic ending of a character in a novel. Why can't we give them a happy ending, or even a future.
The protagonist is actually not fixed
Intention: Go back to the past and try to make up for all the regrets
