Underfell AU
Warnings: noncon; gore and violence; I'll update these as I go.
When you fall into the terrifying world of monsters that is evidently kill or be killed, and escaping from the insanely controlling goat lady, you're quickly discovered by the skeleton brothers. Papyrus captures you and keeps you in his possession while the Royal Guards' attention is more spent on the king's health than on human captivity. Despite the constant abuse and poor treatment you receive during your imprisonment, you slowly start to see that perhaps the Terrible Papyrus has a soft side, and isn't all that terrible after all.
It's only been a few years since monsters have been released from their underground prison. In some towns, monsters are welcomed with open arms. Others? Not so much. Y/N is a 22 year old girl that lives a pretty simple life. Sleep, eat, work, relax at her daily cafe, go home, sleep. Then the routine starts again. However, her routine is thrown off when she keeps running into a skeleton, supposedly named Sans. She would like to get to know him more herself, but there's one problem.. He doesn't talk.
Of course, Undertale belongs to Toby Fox, not me lol
