(Y/n)'s P.O.V

I woke in a weird place.... It was blank.. All white... It's so lonely... I stood up but falling again and saw my hands in chains and with my throat tied hard that I can barely breath.

"Hello? Anybody there?" I said still choking but tried to say a word at least to know if anyone is there. In a moment no one replied and take a look around and heard a very familiar voice but it was a higher pitch than normal does that makes sense?

"who's there? is someone there?" The sound was coming from the other side.

"Yes there is."

"why are you here!? this is not a place for a women like you to be stuck here."

"I don't know actually... I just blanked out and I ended here."

"well my name is sans! sans the magnificent!"

"Hi! My name is (Y/n)! Uh, it's weird you kind of resembles Papyrus especially with the 'the magnificent!'part."

"Papyrus? You mean my brother? Please all he do is sip his honey and sleeps a lot. I am not like my brother! I the magnificent Sans is much better than him! But he is still cool I'll give him that. MWEH HEH HEH HEH!!"

"Uhhhhh....." Is that really Sans? Why is he acting like all, Papyrus?

"What's wrong? What au do you belong?"

"It's undertale."

"Undertale? Awesome! What monster are you anyway? The magnificent sans is just curious."

"I'm not a monster Sans." I said smiling a little.

I can feel he is not UF Sans or UT Sans this one is very different. It's kinda adorable in a way.

"Wait if your not then, are you a..." I heard footsteps walking towards me.

I stood up from my place and looked at the sound.

"Your a human!?!?!" He said appearing.

He wears blue scarf pretty similar to Papy. Then suddenly from white pinprick eyes. It became stars.. And he started shaking rapidly...

"ITS A HUMAN!!!!! I FOUND A HUMAN!!" He said rushing towards me, it was scary!

I closed my eyes ready to take the impact but it didn't came. I opened my eyes seeing Sans in a orange aura around him, he is still moving trying to go to me but he just stayed in place.

"sorry 'bout that he gets excited when he sees a human. also he just drank coffee so yeah. you new around here?" Another familiar voice came from the shadows.

It was Papy! But looks like Sans... Honestly this is freaky but adorable and awesome at the same time!

"what is happening?" I said that was suppose just to be in my head.

I was thinking out loud.

Papyrus gave me a angered look while Sans is confused. I bite my lower lip and hide my face. Wow! What a great first impression to Papyrus who seems like a overprotective brother. I'm sure I'll be fried next chapter.

--time skip--

"PAPYRUS!!!! STOP WITH THE TERRIBLE PUN!!! ITS NOT FUNNY!!!"

"come on, it will be SWEET of you if you laugh." Papyrus said taking his honey out and showing it to Sans' face.

Sans is so irritated now. I just laughed at the whole scene. I noticed that they came from Underswap. Where everybody is switched personalities. Papy is swapped with Sans, Asgpre swapped with Toriel, so on and so forth. I was enjoy seeing them have fun at each other, mostly Papy only. Until someboy came in...

"wILl yOu jUs-s-sT!! sHuT Up!!" The shadow shouted..

I can't really tell who cuz he is somewhat hidden. He sounds like Sans but with error and glitching sounds.

"We're sorry..." I said.

After a long silence the 'shadow' went out. Stomping out. I looked at the bros and there old smiles turned to sadness, fear and anger at the same time. After a another long silence Sans spoke up.

"Papy, I'm scared..." He said shaking hugging Papy.

"its ok we will go home soon i promise." He said soon Sans hugged Papyrus.

I watch how they cried... Seeing the two of them suffer... Just makes my heart break...

(Underfell Sans' P.O.V)

Something is not right... I haven't seen (Y/n) since the explosion which is this morning... Half the day I didn't saw her lingering... I asked Tori and Frisk if they seen her but no, they told me she ran away, even Flowey, he said she went off somewhere. I am now heading to my station in Snowdin since I have nothing do. When I arrived I sat and put my feet at table, I was falling asleep until something came... Somebody was opening a portal. I kept my eye shut pretending to sleep.

"(Y/n)?!" A sudden, yet very familiar frantic voice said.

I opened my left eye to see if who was that. I saw someone there looking for something then I said. Wait, how he knows (Y/n)?

"how did you know (y/n)?" I said rising from my chair and looked at him directly.

He wears similar clothes as me but with instead of red its blue, and black to white. I hate blue.. His teeth are less pointy and their is no golden tooth.

"I'm taking her home."
