Reset (An Undertale Fanfic)

For a long time, monsters have dreamed of having the freedom to roam the surface. It's been a dream of Sans for years. Not to say he isn't at peace with the life he has. But when a human named Frisk falls into the underground, things start to change. What can he do when he's forced to relive seeing everyone he cares about die over and over again?

(I don't own any of the characters. These characters belong to Toby Fox.)
