Humans and Monsters have been living together on the surface for a while now, but humans still don't seem to accept them in the community. Not all humans accept monsters, and now they are treated as low lives. You are a human who lives with your adoptive monster parents, and you can't understand why no other human can see how pacifistic they really are. After going to your favorite diner, Grillby's, you meet a monster who has the potential to change your life forever. Will the encounter be fate, or was it the mysterious pun master's intention?

Hiya! This is going to be my first fan fiction. I have recently been obsessing over undertale, and sans is my favorite character. I have already read a lot of sans x reader and decided that's what I wanted to write. I don't know how long this story is gonna be or how often ill update, but ill see how it goes and if you guys like it I might do more in the future. XD wish me luck! Ps. I do NOT own any artwork that may be used.

Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister.
