You are Y/N. You fell down Mt Ebott and into a world filled with monsters. Of course, at first you were terrified of these monsters. But you soon grew to love them all like they were family.
You soon developed a crush on a certain, big-boned, pun-filled skeleton. Of course, that was Papyrus! Nah, it was Sans.
Sans starts hinting things to you, like how he loves you so much. You weren't for sure if he had a crush on you too..but maybe he's "Falling for You.."
