[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are finally falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they?
