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 -

Monsters have returned! (Y/N) is waisting no time to find out more! After running into a hyper skeleton twice you slowly start meeting and growing attached to a new group of monster friends. One however is more likeable then you thought. (This is Sans x Female reader)

What would happen if Sans had finally found his soul mate? What if his soul mate was Frisks older sibling? Read to find out.

Uh

Um.

This is my own stroyline, it may be a bit bad but I hope that most of you enjoy! Ps. I don't own anything but the storyline and simply a few ocs. I don't own any of the good art or videos in this, only some //bad// drawings. This has nothing physically sexual Just one flower dirt-y joke (Sorry Pap/Swap!Sans) Only mild swearing AND PUNS!!!!! PLEASE READ FULL STORY!!!

What if I never fell down here? What if Toriel didn't find me? What if I didn't choose this path? ... What if I never met you...?

After Frisk goes missing, Caitlin, Frisk's twin sister goes looking for her in the the last place she saw her. MT Ebott, the mountain of dark legends, she finds a necklace that belonged to Frisk on the ground. Just like Frisk, Caitlin tripped and fell into the Underground. Caitlin finds things she never knew existed.

The three powerful humans in control... Frisk- pacifist. Can reset. Chara- genocide. Can reset. Y/n- Neutral, though they haven't ever killed anyone. Can't reset. Y/n falls. Every timeline she has a single goal. Stop the genocide. Even during a Pacifist Route she can't ever relax. She wants to save her friends and stop the resets. She will be the monsters savior ~Disclaimer~ I DID NOT COME UP WITH THIS IDEA. I READ A STORY JUST LIKE THIS AND THE AUTHOR CHOOSE NOT TO FINISH IT SO I ASKED TO CONTINUE IT FOR THEM.

It's been over a year since the Underground opened up and the monsters living under the earth swarmed to the surface in their thousands. The human and monster governments are taking their sweet time coming to any kind of agreement regarding monster rights and citizenship, but for the most part, in the less politically-active parts of the nation, life continues as it always has. In your sleepy little town, there are bills to be paid, tables to be waited, and few to no adventures to be found. So when two skeleton monsters move into the empty house near the café where you work, you welcome the changes they bring with them. You knew if you let them into your life they'd make interesting friends. What you didn't expect was that getting to know these remarkable strangers would be like coming home.
