   Summary

   A rewrite of a previous fic, changed structure and story and more Sans' to have sex with.

   Years have passed since the barrier had fallen and freed the monsters. You had your found family with them, Sans in particular being your best friend and support. You heard of SOULmates and how monsters have them, you wondered yourself if humans also had SOULmates, and you find out as you begin to travel through different Undertale AU's just how SOULmates and SOULs work through the multiverse.
