Of course this happened, to me of all people. When I was simply minding my own business and reading some of the good old fanfiction I just HAD to fall asleep and find myself in the damned game itself. And you should know that falling is NOT as peaceful as it is in those movies.

When an angsty teenager who has nothing better to do in life suddenly gets yeeted into the fictional (and slightly aware) world of Undertale, what else could you expect them to do other then to walk through this game once more in their gen-z way?

Inspired by "Great, Another Self-insert Fic" by Hyuuint, which could be found on Archive of Our Own, None of the characters except for the one that the MC talks to in the Prologue belongs to me.

One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself. But alas, The sickness gotten worse... -------- UNDERTALE (c) Toby Fox --------- This have nothing to do with Undertale's canon characters or story. This is just a fan story I made because the idea stuck in my head for a few while and I'd like to share it with all of you. So, enjoy!
