A young human runs out of the ruins desperate to get to safety. She runs into the Skeleton brothers Sans and Papyrus. Before she can know what's happening her world is completely thrown upside down. Sans is horrible but Papyrus.... he's not as bad as he makes himself out to be. What will happen to the young girl? Will she be saved or killed? And will she finally figure out the secret her mother was hinting at before she died?

Underfell Papyrus is viewed as one of the most ruthless monsters in the underground but what is really under that tough persona? Thanks to Tamqul on Deviantart for letting me use their awesome artwork as the cover!

Title idea is from @Uwuwulove Note that I update pretty slow since I have classes, and have other things to do irl, so please be patient. plus english isn't my first language, so there might be some incorrect spellings, grammars, errors, etc. oh, and the reader would have she/her/they pronouns here so,,, but if you guys want a gender neutral one, you can ask me and i'll edit all chapters to your liking :D !!May contain some sensitive stuff!! -If this flops, I might discontinue tbh- Some slight chinchikurin content added !!
