When She Came (Underswap Sans x Reader)

STORY IS LOOSELY BASED OFF "Can I Stay?" BY Fruityyloopz WHICH IS A REALLY GOOD STORY AND YOU SHOULD ALL GO CHECK IT OUT YEYE
"It's the underground, but it's not MY underground. Everyone is the same, but different. I don't know what's going on, but maybe I can learn to live here and move on."
