In this world, there is a group of people who have no ending, or just have a hasty ending.
The source is unclear, and the ending has not yet been written.
But a person's story should have a beginning and an end. Therefore, in the vast universe, a "rejection of unfinished ending system" was born.
It binds those people who have no ending and unknown origin, records and writes their past and future.
So, they wake up and go back to the past, but finally move towards the future.
First world:
Money-hungry researchers vs. Mermaid experimental subjects
The second world: the romantic young master vs the cruel and surly beauty
The third world: ruffian police vs blind suspects
Other worlds to be determined.
