   Summary

   Starring Spot and Voidster, before they ended up in The Sin Mansion.

   You're just trying to catch a break from your abusive boyfriend when you head up to Mt. Ebott, but things go from bad to worse when you fall into the Underground in the middle of a reset. Battered by kindness and cruelty, you do your best to survive as you get dragged between timelines. During your journey, you meet a doctor who struggles with morality and the fate of his people; the cruel, perverse skeleton that assists him; a kinder, gentler version of that skeleton; and a man so terrifying that he may destroy everyone you've come to care about. This story takes place in both Undertale and Underfell, as well as the void between worlds...

   PART ONE STATUS: 43/43 Chapters (COMPLETED)
   PART TWO STATUS: 27/27 Chapters(COMPLETED)
   PART THREE STATUS: 9/?? Chapters

   Explicit chapters have been tagged, and I have provided chapter summaries in the end notes for those who want to enjoy the story without seeing the worst of the non-con/dub-con stuff. This fic heavily features W.D. Gaster and Sans as the two main love interests.
