Chancetale sans x reader. (read description plz.)

I wrote this AU myself. I have made quite a few. This is my saddest If I am being honest. Yes it is a sans x reader, and usually this would be frisk, but I will just let you guys be the ones in the adventure! All you need to know is that you have completed a pacifist as your first playthrough, and you are on the surface. You live with sans and papyrus on the surface and you are in a relationship with sans.
Artwork not mine unless I say it is mine.
