JUST POSTING THIS SO ME AND MY FRIEND CAN MAKE FUN OF IT, but it WAS written unironically 4 years ago.
TW: Complete lack of understanding about mutism, grooming undertones, and suicidal ideation/attempted suicide.
Read at own discretion. It's really not worth it.

What would happen...
If Frisk didn't leave the ruins?

This story is about Undertale. But a different timeline. A timeline where Frisk didn't leave the ruins until she was much older. She begins on a quest to free the monsters, but it turns into so much more...

This contains a LOT of Sans x Adult Frisk.

There are also some really violent scenes, and cursing.
