The Vet and the Skeleton (Sans X Reader)

Totally Normal Day

Hi there! This is the first chapter of my fanfic! This will contain mature themes and swear words, so if you don't like it then stop reading! All right, let's get to it!!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Now listen here everyone, we must protect the children. They are our future, especially the chief's daughter (Y/N). She must at least make it out alive. Otherwise we are all in grave danger!"
This all seems familiar... Why can't I remember it?
"(Y/N), you need to make it into civilization and only then will you be safe. Find the woman named Samantha Crest!"
"Commander! They're coming!"
"My child, you may not know this yet but you have a gift. A very powerful gift that it can be dangerous if not used correctly. Now go!"
Running, it burns, my legs are burning! WHY CAN'T I REMEMBER?!?
(Y/N),
(Y/N).
(Y/N)!!
WAKE UP!!!
Elegantly you fall out of the bed and wake up to an angry blond woman with red streaks. Her doe brown eyes stare angrily into your own. You start to realize that you are upside down when it looks like she is smiling instead of frowning. You start to feel guilty about the situation in front of you.
"Um, morning Sam. I guess I slept in again huh?" You attempt to pick yourself up from the way you are looking and in result, the rest of your body falls and so does your face. "Ow, another great thing I get this fine morning. I hope I didn't-"
"(Y/N)." You look at her, she looks like she found you stealing her credit card to fix your broken car. "I got a call from one of your teachers saying you missed a therapy group class." In her eyes you see a hint of disappointment along with the anger. You had your own reasons for missing out on this ONE lesson.
"Ugh Sam, I told you I want to find a spot for my veterinary hospital. Having a masters and being the top of my class of school wasn't for nothing. Plus I saved a deer from getting hit by a car, at least I think it was a deer?" (Oh! Hello! I'm the author and I forgot to mention that will change the story! This is an Undertale themed story if you haven't noticed and this takes place on the surface, post-pacifist route. Onto the story!) You think back to yesterday.

Flashback noises ~~woosh, woosh~~

It was a busy day in the city and monsters were just reintroduced to society. Honestly it was a lot to take in at first, you couldn't help but feel bad for the monsters that were harassed on a day to day basis. They were set free by a seven year old who is also their ambassador. If you think about everything and what has happened, it gets confusing. You WERE on your way to your lesson, key word "were", when you were distracted by something else or rather people's voices.
"Hey! Go back to where you came from you freak!"
"Yeah! Go into the hole where you climbed out of and stay there!"
"Aww you don't like that, then let's put some eyepatches on you then! That will make your suffering more enjoyable!"
Three large men were circling a monster, at first glance you can mistaken it for a deer. They were forcing eyepatches on its eyes, causing it to panic and run into a wall. You looked at the poor thing and felt something swell up inside you! You felt DETERMINATION! You walked up to the possibly drunk men and stood up for the poor monster.
"Hey! Stop hurting it, otherwise I'll have to use brute force!" Yeah, you were a black belt in martial arts. These guys were going to have their asses kicked if they refused and tried to hurt you.
"We were just trying to have some fun, but I guess we could have more fun if it's with you" he slurred. Yup, definitely drunk. You looked behind you and saw the deer (?) trying to get back up, and noticed it winced when it moved one of its legs. You turn back to the bastard that did this.
"I'll warn you again, leave or else." One of his friends then attempted to go behind you and grab your butt. That's when you right hooked him in the face and he fell down with a forming black eye. You look straight into the man's eyes and say "Now you aren't going to have any mercy."

Time skip because it would take forever to write a fight scene.

Like frightened dogs, the drunk asses ran with their tails between their legs or tried to at least. Looking behind you see the monster sitting with its injured leg out. You take off the eyepatches and look at the monster in its eyes. It seems scared because once the patches are off, it starts to shake. You try to comfort it.
"Don't worry, I'm not going to hurt you. The ones who were are long gone. I'm a doctor and I can help, can I see your leg." At first it hesitates and slowly it moves its leg and you look at it very carefully. You notice that it isn't broken, it just popped out of its socket. You seem weary about what to say to the monster. "Alright buddy, I'm going to help you but it's going to hurt. Do you trust me?" It looks surprised that you even asked it if it was ok with you going to help them. In response it whispered out a tiny yes. Before you placed the leg back into place, you move the monster into a more comfortable position. You take off the scarf you were wearing for the monster to bite down on while you did what you had to do. "Alright, ready?" You waited for a nod of approval and it gave you just that. "1...2...3!" At the end of 3 you pushed its leg into its body where the leg and socket should meet. It was probably a good idea that you gave it your scarf because its screams were now muffled. After 5 minutes, the screams died down and the monster could now walk with a small limp. It tried to hand you back your scarf but you denied. "A little gift from me to you, to show that not all humans are bad." It stared at you and then wrapped it around itself and said goodbye and left. You then realized what you did took all day and you had one word to say about this. "Shit."

Flashback end

You stared back into your guardian's eyes and looked upset. "What was I supposed to do? Look away and pretend nothing was going on!" Samantha looked upset and took a while to respond.
"You continue on with your life, someone else might have helped that monster soon after you left."
"The keyword there is 'might have' and it might have it been later when someone would find pile of dust." You both stare each other down and you decide to put on a pair of clothes. A black t-shirt with some jeans and your converse. When you are just about to walk out the front door, Samantha stops you.
"Where are you going?!?"
You look back and say "anywhere but here" and walk out the door.

Time skip cuz I'm lazy.

You eventually made it down the city and besides the argument you had with Sam this morning, it has been swell. While you walk around the busy streets you see many shops that were added because of the monsters that arrived on the surface. Some people were peaceful and others, well, were assholes. But every monster that you have met so far has been so nice! Better than some other people you know. As you were done crossing the street you couldn't help but notice a small child looking at a caterpillar in the middle of the street. You look to your left and there comes a speeding car and the kid is in that car's path. You sprint towards the kid who had just placed the bug on their hand and pick them up and run across the street. Panting heavily you put the kid down as the car speeds by. Looking at them you question why they stopped walking. "Kid, never stop in the middle of the street. Please, it almost got you killed!" The child just smiled and nodded, they placed the caterpillar down and gave you a big hug as a sign of thanks. Then a large goat monster in a purple dress comes running and starts to cry tears of joy.
"Frisk my child! There you are, you had me worried sick! One minute I was looking at a book in a store with you and the next you are gone! Please don't do that ever again!" The child now called "Frisk", is doing some movements with their hands and you think this is your time to leave. Just as you are going to turn around, Frisk looks at you and so does the goat monster lady. She looks surprised, "Oh! You are the one that saved my child from a car?"
"Uhhh, yes?" She suddenly grabs onto you, hugs and releases all the air in your lungs.
"Oh my stars! I can't thank you enough for what you did! Thank you so much!" Your vision starts to fade out on you.
"Oxygen... need air... sight becoming blurry... tell John... I ate all his macaroons..." As you think you are going to feel the sweet release of death, you are sucking in air like a lifeline when the lady stops hugging you.
"Oh goodness me! I am so sorry for two reasons! I haven't even introduced myself!" When you are done acting like a fish out of water you look up to the woman. "My name is Toriel, the previous Queen of Monsters." Oh, ok. Oh. OH. This is the fucking queen. The previous ruler. The one that can snake sense into her husband and still look like a badass while smart to her people. You start to feel anxious, and feel a familiar sensation throughout your body.
"Should I bow or-" she interrupts you before you can speak any further.
"Please don't, I'm fine with how you are now. Hmmm, huh? What is it my child?" The kid starts to make more hand signs and you really wish that you knew what they were saying. "That's a wonderful idea Frisk!" Toriel looks at you with the uttermost glee in her eyes. "Please come by our house for dinner tonight! That way we can get you to meet all of our friends!"

Wait, what.

You did not sign up for this. All you wanted was a normal day and instead you save a kid that you don't even know what they are saying.

On the other hand, you are still mad at Sam for yelling at you this morning. So it would be a great way to take your mind off things!
"Sure! Why not!" Then, you start to wonder if you are going to regret this choice.
"Alright! We shall meet my house at 6:30! Here is my phone number that way I can tell you where my house is! Come along now Frisk! We have food to prepare!" Toriel starts to the direction of where you think her car is and before "Frisk" leaves, they turn and wave you a happy good bye.

"Yup, totally normal day today."
