What if one day you find yourself facing two people who introduced themselves as gods? And what if they told you that you have died and that they wanted to reborn you in a new world? But, that world turned out to be the world in a novel you used to read.
However, that novel had a shit ending in which all of the main characters died in the end.
It caused a rift of anger from the readers. Enough for them to vent their anger on social media and send death threats letters to the author.
Since the novel's ending wasn't well accepted by the readers, the goddes asked you to create a better ending.
"I see. I'll do it."
