Warning! There is a chance that there will be spoilers for the pacifist run of undertale. I recommend finishing that before reading this. There won't be any spoilers for the no mercy run, so don't worry about that! Also, don't worry about anything NSFW/lemon if that's not what you're into-there won't be any of that here. You're a human that's fallen down into the underground. You've decided that you'll stay instead of going home after fighting Asgore and sparing him. Now, you had made some great friendships while in the underground-but one of those friends in particular was one you'd like to be a little more than friends with... Aaaa an X reader fic! I haven't done one of these before, but I hope you still like it!

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.

It has been 10 years since the monster broke free from the barrier, and since then monsters and humans live together in peace. But for some reason, monsters have somehow got a mini version of themselves, no one knows how or why it just happened. And for some reason, the skeleton bittys are popular because of their many different versions. You are a 19-year-old girl who lives in New York City in your apartment the problem is that you're all alone( if you're wondering if your family is alive, you just live far away from them), you have a small dislike for people. You wish you could get a Bitty to hang out with it, but the problem is that it costs a good amount of money. So you could never get one or so you thought until one day you find a strange box. This is my first time posting here so I hope you enjoy it! Also note there is some swearing. Note the cover does not belong to me. It came from https://undertale-au-fanon.fandom.com/wiki/Bitty!_Sanses By The Edit Lord Also I do not own any of the characters. Undertale belongs to Toby Fox.

Sans is struggling with an unexpected, and incomprehensible...illness. With the help of Papyrus and other friends Sans will surely make it out of this conundrum... right? ~Characters belong to: Toby Fox/creators of Undertale ~Any and all character thoughts/descriptions/etc. are from me -cover original image: https://img00.deviantart.net/8d12/i/2015/329/1/c/it_s_okay__you_can_cry_now_by_lemonsandlemonade7-d9i1gq9.jpg

One's been abused, the other's experienced many genocide runs. For once both can be happy.... but sometimes life isn't fair. Sometimes, we can't have nice things.
