A livestream System from a distant age of interstellar civilization was split open by its creator and sent through time to an ancient era that had long since vanished from the records. It helps all kinds of people with regrets change their fates, while bringing entertainment to humanity in the interstellar age. The livestream System will have a much smaller role later on, and there will not be many scenes featuring interstellar viewers either, so they won’t distract from the story. You can just think of it as being reborn with a golden finger.
There are mountains of my own headcanon, and the timeline and plot may have nothing to do with the original works. Just enjoy the ride.
First world: Consort Hua from Empresses in the Palace
