You shift uncomfortably in your bed, your breathing hitching in annoyance at a random tickling sensation that poked at your nose. When you took another breath in it came back, causing you to groan. 

"Alicia Monty, I swear. I just want to sleep in for five more minutes." You grumble, not really in the mood to figure out why your voice was so deep. Turning to lay on your side, your eyebrows furrowed down in confusion, fingers wiggling around in what felt like wet dirt. 

Ever so slowly did your eyes open, taking in your unfamiliar surroundings with confusion swimming around in your stomach. This wasn't your bed and it certainly wasn't any part of your apartment. 

You push yourself up onto your rear, head twisting and turning to try and decipher just where in the world you were. What you did know was that it was absolutely stunning. 

The soft sound of running water soothed your hammering heart, most likely coming from the nearby waterfall to your right. The water seemed to be glowing beautifuly, traveling down to a small stream that swam past your small island of dirt along with a small wooden bridge that connected both sides of dirt. 

Were those flowers also glowing? Tall unidentifiable blue flowers towered over the rivers bank, swaying side to side from a force you couldn't feel. Above your head you could spot small glowing stones that closely resembled stars, either way they still took your breath away. 

With your head held high to gaze in awe at the ceiling, you finally stood up onto your feet, idly pushing off the small blue petals that had been tickling your nose earlier. 

"It's beautiful." It barely came out as a whisper, your body moving forward on its own until you noticed you had stepped into a puddle. You go to take a step back but paused in your movements. 

Staring back into your eyes from your reflection in the water seemed to be a skeleton. Its large black and empty sockets wide, staring back up into your own eyes. Its mouth seemed to be pulled down into a tight frown, teeth looking like they were somehow molded together. 

This skeleton didn't seem to have any fashion either. An unzipped blue hoodie covers the white t-shirt that covers their bones, black shorts with a white lining and are those salmon-colored slippers? 

You shakily raise a hand and the skeleton follows your move. Waving the hand in front of your face you realize that this skeleton was in fact you. When this dawned upon yourself, two white pinpricks appeared in those dark sockets, filling the abyss with tiny lights. 

"No. No, there's no way." Your baritone voice wavers, feet stumbling backwards away from the water. You laugh nervously and cover your skull with your skeletal hands. "I'm dreaming. Yeah, I had too much to drink last night. When I open my eyes I'll be back in my warm comfy bed." 

You take a few silent seconds to prepare yourself, inhaling and exhaling through your nose. When you peeled your hands from your face you were disheartened to see that you were still in the same spot you were seconds ago. 

Alright, so there must be an explanation for all this, right? Oh, who were you kidding. You didn't even know where to start. This all seemed too surreal for you. How were you supposed to explain something like this? You needed answers and you needed them now. 

Anxiously fiddling with the zipper of the hoodie, you start to drag your feet across the wooden bridge, eyelights scanning the new scenery. You wouldn't lie, everything was gorgeous and breathtaking. 

The walk to wherever you were aimlessly going was filled with the peacful sound of the rushing waterfall, which helped calm your nerves. In the very back of your mind you still held onto the hope of this being a dream, no matter how small that possibility seemed. 

Time ticked by quickly, yet you didn't really notice when you had no idea what time it actually was. The dirt path underneath your feet began to dissipate into white fluffy pieces of snow, which caused alarm bells to ring inside your skull. 

Snow didn't work like that, not at all. It was like someone just randomly cut a line down the middle of these two opposite places, one side with snow and the other with a moss like ground. Also, how could it possibly be snowing when it seemed like you were in some sort of cave? 

Not really wanting a headache to form, you pushed those nagging thoughts away and trudged on. You guessed you were lucky, in some weird way. You were a skeleton, so you couldn't really feel the cold against your bones. 

"At least one good thing came out of this." You grumbled, still unnerved at the different tone of voice.

A thick fog greeted you first, making it difficult to even see your own two feet. You mentally crossed your fingers and hoped nothing was lurking away in the fog with praying eyes on you. That wasn't what you needed right now. 

You breathed a sigh of relief once the fog began to lift, your eyes finally adjusting to the snowy ground beneath you. Trees upon trees lined the path, delicate snow sitting on their branches creating a magical atmosphere. Perhaps you were dreaming, none of this seemed real at all. 

Finally, you spotted something ahead that brought confusion and relief to your mind. It looked like a house and a small shed. Trying your hardest not to question it you quicken your pace towards the house, excited to finally see a normal face. 

You went to raise a fist to knock against the door until a loud voice made their presence known behind you, "SANS! THERE YOU ARE!" 

Biting back a squeak you instead headbutt the poor door by jumping forward in fright. Hissing quiet curses to yourself, you slowly turn around and rub at your sore skull though pause mid rub at the sight. 

Another skeleton? Seriously? Was your mind playing ticks on you or something? Were you alcohol poisoned? 

"SANS! ARE YOU LISTENING?" The surprisingly gigantic skeleton places his hands on his narrow hips, eyes narrowed down at you. 

You just blink up at him, staring with the most confused face you could muster. Gathering that he was talking to you, you point a finger at your chest, "Me?" 

The skeleton - a male you assume - sighs in frustration and pinches the space between his eye sockets, "YES YOU! DO NOT PLAY THESE GAMES WITH ME, BROTHER." 

Oh, so these two were related? Okay, now you're getting some answers. For now, you decide to stick to the down low. A mental asylum didn't sound delightful. 

"Oh, uh. Heh, gotcha' bro." You weakly send him a pair of finger guns, chuckling sheepishly. "Uh, did you need something?" 

"DO YOU NOT REMEMBER?" The skeleton who you still haven't figured what his name is, crosses his arms, a foot tapping against the snow, "YOU WERE SUPPOSE TO BE SHOWING FRISK AROUND THE UNDERGROUND!" 

Frisk? Who was this Frisk? Were they a skeleton too? Underground? Damn, what drugs were you on right now?

Answering your unheard questions, a small human child pokes their head out from behind the tall skeleton, their brown head of hair covering their eyes. 

"THEY TOLD ME YOU WERE NAPPING AT WATERFALL AGAIN AND NO MATTER HOW HARD THEY TRIED TO WAKE YOU UP, YOU JUST WOULDN'T BUDGE!" 

"O--Oh." Your grin was strained at this point. Keeping this act up was going to be harder than you thought. "Sorry about that, Frisk. You know I'm a deep sleeper." 

At this, Frisk seems to narrow their eyes at you. Shit, did you do something wrong? You didn't even do anything! Your posture tightens and goes rigid, shoulders square and tense. Was that sweat forming on your forehead? 

Awkward silence gathers between the three of you, it was nearly enough to suffocate you. Thankfully Frisk picked up on it too and began to move their hands - Sign language! Now this you could understand! 

For once you were glad your parents had forced you into doing something. When you were in your early teen years they had wanted you to learn and understand sign language so you could possibly become a translator or an interpreter sometime in the future, mainly because their salary was fairly decent. 

'Can Sans and I visit Grillby's for lunch?' You picked up from their hand signals, a bright smile on their little face. 

The skeleton in front of you seemed to dwell on this question, a hand rubbing his chin, "WELL, AS MUCH AS THE GREAT PAPYRUS DESPISES GREASY FOOD, I WILL ALLOW IT!" 

Did he just refer to himself in third person? At least you got his name and could finally stop calling him tall skeleton. 

'Thank you. We'll make sure we're home in time for dinner.' Frisk seems to smile even wider, flashing Papyrus a pearl white grin. They then turn to you and reach out to grip your hand, already leading you away from Papyrus. 

The walk to this so called Grillby's was short and silent. Frisk kept glancing from you to their feet before repeating the whole process. You didn't want to speak up and give yourself away so you opted to stay silent and let the kid drag you along like a dog. 

The first building you went by was a library, though the sign was spelt wrong. There was a shadow through the tinted window, but you made sure to keep your head forward. No need to be getting into things you don't understand. 

After the library, you passed by two... people? No, that was wrong. They weren't like any person on the street that you've seen. One looked like a small devil and the other... it was hard to say when they were covered by a large scarf. All you could tell was that they had large mouse like ears and a small tail. 

You were so far in your mind trying to comprehend what was going on that you didn't notice Frisk pull you into Grillby's. The atmosphere in the bar was a different contrast to outside. Even the customers were different. You had a small hunch on where you were, but how you got inside this Sans' body was a whole other mystery. 

Funky music was the first thing you picked up. It wasn't something you could jam out to but it had a nice rhythm to it. The next thing you noticed were the different shapes and sizes of the Monsters strewn about the bar. 

There was a table full of humanoid dogs that looked to be playing some sort of card game, and were those two dogs holding axes? Why were they dressed like reapers? There seemed to be some drunk bunny to your right and a sharp toothed plant sitting in the booth behind them. 

Tugging at your sleeve was Frisk, who looked up at you impatiently. "Sorry, sorry." You raised a hand in your defence and watched the small child walk away confidently to take a stool at the bar, leaving one empty next to them for you. 

Giving everyone an uncertain look, you quickly shuffled up to the stool and sat down, propping your arms against the table top to try and seem casual. Turning your skull towards Frisk, you go to open your mouth to question them about lunch until a bottle of ketchup was placed in front of you. 

You freeze in surprise and ever so slowly turn to face the culprit. A man on fire stared back down at you through a pair of glasses, the flames on top of his head crackling softly. No, you were wrong. This man was made out of fire. 

"You're hot." Were the first words to leave your mouth, your gaze never leaving the mans glasses. He didn't seem fazed at all, instead he looked borderline annoyed. 

"You've used... that one already." The fire man spoke, somehow with no mouth you must add. Plus, he spoke in a hushed whisper, which you barely picked up. 

"I have?" You break your staring and idly tap your fingers against the bar top. You didn't dare look back up at the man of fire and instead kept your eyed on the ketchup. "I'll come up with something clever next time." 

Silence settled over the three of you. You must be an expert at creating awkward silences, so where's your prize? 

Clearing your throat -how does that work?- you tilt your head up to face the fire man, "Uh, am I getting fries with this or...?" 

Something akin to shock washes over his face, and from your side vision you could see Frisk raising an eyebrow at you. Your almost always permanent grin falters for a moment, eyelights drifting from the human child to the fire guy. Wow, you're really bad at names. 

Frisk pays you no attention and instead shifts on their stool to face the fire man, their little hands moving to form the words, 'Give us a second, Grillby.' 

Ah, so he was Grillby. Made sense, you guessed. Fire man, now named Grillby, nods stiffly, sends you one last puzzled look before walking away into the back section, the sound of his flames getting further and further away before all was silent again. 

Intrigued and mildly afriad of your secret being uncovered, you kicked your small legs a little underneath the stool in nervousness. Smile twitching, you titled your head down at Frisk, "What's up--" 

You didn't get to finish your question before their hands moved fluently, 'You're not Sans, are you?'

Luckily, you weren't sipping a drink at that time because you were sure you would have spat it out or choked on it. You clutched at the sleeves of the hoodie, body going tense. 

"What're you talkin' about? 'Course I'm Sans, who else would I be?" At this point you were struggling to keep your voice from cracking under pressure. 

Frisk's stare wasn't helping your situation. It felt like they were studying you, picking out all the little imperfections, searching every nook and cranny. Like they could see right through your thin clothes, right into your SOUL. 

Your breathing stills, eyelights dilating. SOUL. "Holy fuck." You breathe out, propping your elbows up against the bar top. You rested your head against your open palms, eyesockets unblinking. "It all makes sense! Soulmate, oh shit, oh shit!" 

You were on the edgr of hyperventilating, your shoulders rocking up and down at your quickened breath. A soft tap against your arm sends a shock through you, snapping you out of your thoughts. 

Frisk seems to have a cocky little smirk on their face, which basically read 'I knew something was up'. Huffing, you shake your head, "Fine, you were right. How'd you know? I thought I was keeping it cool." 

'Sans would have cracked at least twenty terrible puns by now, and he rarely uses the same one.' They giggle, seeming to recall memories to themself. 'That and you didn't drink the ketchup on it's own. Oh, and Sans never walks anywhere. He uses his special shortcut.' 

"Wait, hold on." You raises a skeletal hand, horror in your expression, "This guy, my Soulmate, drinks ketchup?" If the disgust wasn't clear in your voice, than pushing the condiment away from you was enough to display it. 

Frisk snorts into their hand, more giggles erupting from their mouth. Past that point, you both talked for what must have been a few hours. 

Frisk was determined to keep the topic of Soulmates up. You responded how you usually did; You thought you never had one. When you were younger you expected to have some special bond with this special other person, but your hope was diminished after the age of eighteen. You thought you'd always be alone, the question of 'why me?' always holding you back from moving on from something you never had - or so you thought. 

After finally wrestling the topic around into Frisk, you asked them how they got down here - providing that you were actually where you thought you were. 

And so Frisk gave great details on how they managed to trip down into this little civilization under the ground. How they met a misunderstood flower, a goat mother and how they were great friends with both Sans and Papyrus. Throughout the whole story, you got a weird feeling that they weren't telling you something, or that they were hiding something bad. You kept that feeling to yourself and pushed it under the rug for now. 

You talked more about Sans, how he acted, what he did around the Underground, what kind of skeleton he was. You got a pretty good image of the guy now, and you admitted that the two of you were somewhat alike. 

Sometime through talking Grillby joined in, and you ended up spilling the beans about the whole thing. It was mainly because he was close to Sans, therefore you could trust him. He seemed nice anyway, even if he was the silent type. 

Realizing how much time had passed, Frisk was quick to pull you out of Grillby's Bar with a quick goodbye to the fire guy over your shoulder. 

"What's the rush?" You grip the kids hand tighter, trailing behind in their footprints. 

Frisk looks back to you, having to let the grip on your hand fall so they were able to communicate, 'Papyrus will kill is if we weren't home in time for his dinner.' They pause, 'Well, the dinner might kill us first.'

"Uh--What?" Your giggles start to slow seeing the seriousness in Frisk's expression. "Frisk?" 

They break into a sheepish smile, waving a hand dismissively, 'You'll understand eventually.' 

None of that helped the worry eating at your stomach - or what stomach you use to have. Frisk looks like they were getting a kick out of your pain, their grin widening. For a moment something seemed sinister about their smile, but it was gone within a flash. 

You didn't get time to think about it before Frisk marched up to who you assumed to be both Sans and Papyrus' home, their small hand grabbing the knob and opening the door without a knock. 

The door swings open with a small squeak, which must have reached Papyrus from the kitchen. Both you and Frisk enter the house, shrugging off any snow from your clothes when the boisterous skeleton pokes his head out from the kitchen, "THERE YOU TWO ARE! I WAS WONDERING IF I HAD TO COME AND DRAG YOU AWAY FROM THAT PLACE! DINNER IS READY!" 

And you still weren't use to this guys loud voice. He wasn't yelling, he just talked in a loud volume. "Sounds good, bro!" 

You all end up gathered around the dining table, a steaming plate of spaghetti sitting on a plate in front of you. It looked okay, at least. Edible. 

You glance over at Frisk who sat across from you, their plate untouched. Why weren't they eating? You didn't see them eat anything at Grillby's, so they must be hungry. 

Narrowing your eyesockets at them, you gather a mouthful of noodles around your fork and bring it to your teeth. The first chew was enough to make you flinch, eye twitching. Why was it crunchy? 

You did your best to chew quicker and get it down your throat, ignoring the burnt yet weirdly uncooked flavor dancing on your tongue. Now you understood what Frisk meant. 

You would have made up some lame excuse about eating at Grillby's to avoid eating that death trap, but the excited and proud look Papyrus had on his face was enough for you to suck the pain up and eat the stuff, much to Frisk's amusement.  

After that whole fiasco, Frisk kindly shows you Sans room with a quick warning about how messy it was and to be careful where you stepped. Wishing them a confused goodnight, you turned to the door and pushed it open. 

The room was pitch black, which you were glad for. You shut the door behind you and fumbled around the wall for a light switch, flicking it on once you located it. 

Yeah, this guy needed a woman's touch. Socks and other article of clothing were thrown about, a dirty looking treadmill sat in the corner and was that a tornado? You wouldn't question this guys decoration skills. For now anyway. 

You shuffle your way to the unmade bed, face scrunching up at the thought of what mess was hidden underneath all the sheets. No, you couldn't handle this. You needed to fix this up. 

So you did. You found a clothes basket and went around the room picking up all the ketchup stained clothes, plus the socks too. With the room now somewhat tidier, you place the basket by the bedroom door. Hmm, could you leave him a note? 

That's if you'll ever switch back and give him the chance to read it. From what you could remember about these Soulmate bonds, there were days you would swap bodies randomly. So, you could only assume you'll get your body back? 

No, you didn't want to think about the consequences. You should just be happy that you have a Soulmate to begin with. 

Huffing out a small sigh, you turned around to find a pen and some paper. It didn't take long since the guy had a whole drawer full of that sort of equipment, you even swore you saw some blueprints. You didn't go snooping though, he had his own privacy just like you did. 

Now all that was left was to write the note and put it somewhere he could easily find it when he got his body back. The moment you finished, you stuck it on the inside of his door and went to try and clean up his mess of a bed so you could sleep on it. 

'Nice to meet you, Mr Soulmate? I hope you didn't cause any trouble in my body while I was away and you better not have felt me up. I'll know >:( Also, I know you're name so just in case you didn't know mine, it's (Y/n). Oh, I hope you'll at least try and keep your room this clean from now on, and no I didn't snoop around. You're welcome.'
