   Summary

   the story of us, written by yours truly.

   (And me, too! Sometimes.)
   --------

   Sans meets a strange woman, named Lumen (who has the same name of a character in his favorite show), while tending his convenience store. With the sudden interest of sex between a monster and a human, he easily finds sex within the strange woman. He slowly falls in love with her, unable to admit it, as he documents the events leading up to the inevitable that pushes their relationship beyond time and space.
