After accidentally falling into the world of monsters and being separated from his introverted twin brother Frisk, who relies on him the most, Fran can only find a way out on his own.
There are many private settings, the original UT time and space, the protagonist is a time traveler, there is no UT in the original world, I don't know the plot, Frisk and Fran are twin brothers and sisters (brother Frisk, sister Fran), the author loves Sans most, and only wrote it for the sake of her husband, so be careful when entering.
The author's first article, the writing style is immature, the front is jerky and the back is smoother, but he promised Ji You to publish it, so he published it anyway.
This article has been written, feel free to eat, it will be updated every day.
Then the author is writing the second article, and will release it again if it is finished.
If the author's interpretation of the UT world is not what you want, just treat it as the author's own AU!
