Two orphan girls fall down into the Underground. ...Just read the story.

I don't get many chances to write so please these will take a while ok. No lemons. Plus I take requests okay guys thanks.

Not everyone is special enough to know exactly where the Underground's secret entrance is. Not everyone is so special as to accidentally fall into it, either. Of course, that is what the Reader did. They meet the whole gang, and one skeleton in particular stands out from the rest, simply because he's the only one like you. Agh! I'm spoiling the story! Well, if you want to know more, you'll have to read on to find out! As per usual, credit goes to Toby Fox for making Undertale and its characters. Art is not mine, either. OH MY GOSH. #1 in sansxreader?! I CAN'T - I CAN'T EVEN -

You've always felt gravitated towards Mt. Ebbot, even in childhood. You don't know why, but it feels like you're being pulled there by some unknown force. One day, when exploring too far, you fell down into Mt. Ebbot. Along your adventure into the Underground, you meet a lot of people, but there was one who caught your eye... {WARNING: May be spoilers for True Pacifist Route of Undertale, maybe not, idk.}
