A New Soul (Sans X Female Reader)

(Y/N) absorbed a monster soul when she was little, gaining skeleton powers. Many years later, (Y/N) and her sister Frisk fall into the underground, meeting Toriel, their new mother, Papy, Undyne, and of course Sans. Will (Y/N) and Sans finally realize that they have feelings for eachother, or will Asgore find (Y/N) before it's too late?
