Alright so, you were the soul of...Whatever trait, you had fallen down with willow and melody, willow went to Mt.ebott for study and melody and you came with, while Willow was writing

Willow: "This is Mt.ebott, legends say any human who falls down here never returns...how interesting"

She accidently fell down the hole, which made melody and you go down with them, Willow got up and so did you and mel, Willow grabbed their book and began writing in it

Willow: "So the drop is around 50 feet...but there are flowers to cushion your fall...I see"

Melody got up slightly after, dusting off her skirt

Melody: "Wil...WE HAVE FALLEN DOWN THE HOLE INTO THE PLACE WHERE MONSTERS LIVE...WE ARE GOING TO DIE...WILL...babe, darling, sweetie, I love you, your awsome and so smart, but this is probally the dumbest thing you've done..."

You 3 began to explore, the place willow named "The ruins" was big there were monsters you managed to befriend, you eventually made your way to snowdin and befriended sans, you 3 were in sans and Papyruses house, Willow was writing in her book about sans and papyru in papyruses room, melody was cooking with Papyrus in the kitchen, and you and sans were watching the TV on the sofa

Sans: "Heh...this is the best part, alphys recommended this to me, speaking of al, im sure your purple friend and her would get along"

Willow sat in papyruses race car bed, studying and trying to understand the particular skeletons

Willow: "Papyrus is pretty easy to figure out..wants to get into the royal guard via capturing a human, is too nice to do so, but sans is a different story...all I know is he has a giant tab, goes to grillbys, likes ketchup, is in the royal guard somehow, and is very chill...hmm...HEY MEL, CAN YOU HELP ME?"

Willow yelled down to Melody, she yelled back

Melody: "NOT NOW BABE IM HELPING PAPYRUS!"

Papyrus finished cooking, handing sans a plate

Papyrus: "WOWIE! HUMAN NICKNAMES...SANS WHAT DOES BABE MEAN?"

Sans: "No idea paps"

Papyrus: "SANS..WHAT DO YOU MEAN "YOU DONT KNOW", DONT ACT LIKE YOU DONT WATCH ALPHYES "ANIME" STUFF!"

Sans: "No idea whatcha talkin` bout pap."
