Remember the good days | Sans x Reader | Undertale fanfiction

A new life begins for you and your little sister, Neelam. That new neighbourhood is the chance you need to erase the past mistakes and those terrifying fifteen years you passed in a foster family.

You are not the only one who's running away from the past. Your neighbour, Sans, affected by a strange illness that's causing him memory loss, is worrying you. At nightime, he's wandering in the streets, lost, like he is chasing after old demons. His brother, Papyrus, can't look after him for the moment. Since you are in desperate need of a job, he's asking you to do that for him.

You know it is not an easy job, but how complicated can that be when Sans is all but cooperative?
