Your pov

You were on the clouds, flying with your parents. You finally showed a real smile. You were playing with the clouds and doing some activities with your parents. You were so happy that you see them again. You laughed. You hugged your parents and you looked up and you saw...

BEEP! BEEP! BEEP! You groaned and hit your alarm clock hard. It flew and smashed the window. You rolled off of bed and grunted. Thanks alarm clock for ruining my once in a lifetime dream. You stood up and rubbed your eyes. You stretched your wings and folded them back. Your wings are  a pair of (f/c) Crystal shaped wings. It looks hard but when you touch it, it's actually as soft as a plush toy. It's fluffy too but when you look at it, it looks hard and sharp. You didn't know why you have wings  but it's a secret and no even your parents know why but they are happy with it and so are you. Its pretty but there is only one single problem. Once you show them to public, they will get you and experiment on you. Just like last time...

Flashback

You and your parents are walking to the park. You were still a kid. Your wings are all showing. People looked at you in awe and took pictures. Suddenly, a man appeared and caught you all in a net. You all tried to escape but no avail. They brought you to the lab. They were doing tests to your father. You whimpered in your cage with your mom. Suddenly, when the scientist injected him with something, he then growled and kicked the man. He flew through a wall and outside. He still went on until he was out of sight. Dad fought the others and freed us. We went through the door and ran as some men tried to catch us. They caught mom and you cried and tried to reach out to her but dad carried you and ran. "MOMMY!!!!" "Don't worry (y/n)! I'm going to be alright! Just run!" You cried and you saw tears on the road. There are still some men trying to catch you. Your dad went to different directions to confuse them and you two saw a cabin. Your father opened it. It was abandoned. He put you there and smiled. "Stay here okay? We are going to go back to you. I promise." He said then ran out. You were left there. 9 years past and they still didn't went back. You were now 13 years old. You didn't believed that they were alive and they weren't. One time, you went to the lab and found it abandoned. You actually saw your parent's corpses lying dead on the ground. The corpses looked recent. You were too late. You went back to the cabin or your house then you never ever showed your wings, afraid that you will also die.

You felt tears but you stopped them and they were gone. You went to the kitchen and ate breakfast. You looked at the time. 7:00. You start work at 10:00. Yes, you got a job and you moved out of that cabin and went to a house in a town nearby. You took a shower and got changed. You changed into your uniform and you wore your favorite (f/c) jacket. You found a jacket when you were 13 and it still looked new but there were a few holes. You soon learned how to stitch and you made it look brand new. You always wear it to hide your wings. You looked at your watch. 7:30. You was about to walk out when you saw a body drop to the ground. That shocked you and you jumped about 1 feet in the air. You saw that he's a skeleton. The monsters were recently freed if your wondering why there's a skeleton. It was still early so you carried him and went inside your house again. You put him on the couch and you saw that there's a knife stuck to his wing. There were scratches and bruises there. You quickly got a med kit and you carefully removed the knife. You put a cloth in a bucket full of alcohol and carefully dabbed it on the wound. You added a little force and you were done. You soon put bandages on it and put a blanket on him. You looked at the time. 8:30. You left a note on the blanket and went out to go to work. You jogged until you reach the place out work at. You went in and you looked at the clock. 10:00. Just in time. You went to your work station and started to work.

Sans's pov

I woke up in a unfamiliar place. I sat up quickly. I'm in a unfamiliar house. I looked and saw a blanket over me. My wing has bandages all over. Hmm. Oh wait. I remember that I saw a guy throwing knives at me and I got hit by one of them and I passed out. Huh. I saw a note on the blanket. I picked it up.

Dear random skeleton that just randomly fell out of the sky,

Hi. You fell in front of my house when I was going to work. I saw that you have some bruises and there's a knife stuck in your wing so I tried my best to heal it. I will return later at 5:00 so just wait. In the meantime, I prepared some food for you in the kitchen. It ion the table. Sorry, that's all I can afford.
                                             -(y/n)
P.S your wings look great!

I chuckled and looked at the clock. 4:30. I guess whoever that was will be home soon. I went to the kitchen and saw two hotdogs with a ketchup and mustard bottle beside them. I ate one of the hotdog and drank the whole ketchup bottle. The door suddenly opened and I saw a woman. She had (h/c) (h/l) hair, (e/c) eyes and she's wearing a uniform if some sort and a (f/c) jacket. She smiled and went towards me. "Your awake! Come on. Eat the other one. Just call me when you are done. I will be there." She went upstairs and went inside a room. There is a total of 3 rooms upstairs. I ate the other one and sat on the couch. She came back with (f/c) shorts and she still has her (f/c) jacket zipped up and on her. She sat beside me. "What's your name?" "Sans. Sans the skeleton." "Im (y/n)! So, where do you live?" "Huh? Oh! Well, I live in (insert a random address here)." "That's just across the street! C'mon! I'll guide you there." She held my hand and then she opened the front door and I saw my house. I blushed because she was holding my hand and it was soft. Wait, what are you thinking sans?!?!?!? You just met her!! Ugh! We were at the front door and she let go of my hand which I almost made a sound of dissatisfaction but I stopped it. She might think I'm a weirdo. She knocked on the door. "OH? COMING!!!" I heard papyrus yell and he opened the door.

Your pov

You saw another skeleton open the door. He was way taller than sans. He was wearing some sort of armor and a scarf. He has orange wings. "I had found sans falling from the sky to the front of my house. He was really injured. I was wondering if you know him" "OH! WELL HE IS MY BROTHER! THANK YOU HUMAN FOR RETURNING MY BROTHER! C'MON SANS! I, THE GREAT PAPYRUS, WILL MAKE SPAGHETTI!!! YOU SHOULD COME TOO HUMAN.... UMM... WHATS YOUR NAME HUMAN?" "my name is (y/n)." "YOU SHOULD COME TOO HUMAN (Y/N)! THIS IS THANKS FOR GETTING MY BROTHER!" You want to say no because you might be a bother and you don't really need food right now but he gave you puppy dog eyes. The cutest one you can see. His personality made it harder to say no. "PLEASE!" "okay! It's hard resisting those eyes and it's hard resisting you papyrus!" "NYEH HE HE!" he went inside and soon came sans then you. Sans sat on the couch and to be honest, it was kinda hot here but you didn't want to get your jacket off because you might get... Never mind. You won't think of it again but you still won't get my jacket off. You sat to the couch next to sans. He was sitting there with his lazy grin. You were sweating because it's so hot in here but you won't complain, it was hot just because of the jacket. "Heya buddy. You seem to be sweating bullets there. If ya take off your jacket, it will be less hot" "no no no! I'm fine!" You say and laughed nervously. Sans seems to find you suspicious. Great going (y/n), you made him suspicious. You two kind of had a awkward silence between the both if you just luckily, you were saved. "THE GREAT PAPYRUS HAS RETURNED WITH SOME OF HIS GREAT AND FAMOUS SPAGHETTI!" you quietly sighed in relief as papyrus handed you and sans with plate of Spaghetti. He sat on your other side and began to eat his Spaghetti. You twirled your fork around the spaghetti and ate a fork-full of Spaghetti. It was great! You hummed in approval. "This is great Papyrus! You should teach me how to do this!" You explained, mouth still full with Spaghetti. "WHY OF COURSE HUMAN (Y/N)!" you ate the rest of your spaghetti and you were the last to finish. You got their plated and put them at the sink. "I'm gonna wash these!" "BUT, HUMAN (Y/N)! YOUR THE GUEST! I SHOULD BE WASHING THE DISHES!" you both kind of argued of who will wash the dishes. Not the mad kind if argue but it's just you and papyrus saying "I will wash the dishes" repeatedly to each other. You ended up washing the dishes. Papyrus gave in but he was still hesitant about it. You finished and you went to the front door. You looked at the clock. It's 6:59. "I have to leave guys! See ya!" "GOODBYE HUMAN (Y/N)!" "bye" you smiled and went out of the comfy house of the skeleton brothers. You walked to your house and got your bike. You cycled to the forest. You put your bike on a nearby Stone and entered a tunnel. This was a secret location on where only you and your parents hang out. It's a field where there are always fireflies flying around peacefully and there was crystals growing on the grass. It's a mystery on why there are crystals growing on grass but it's beautiful. You went there and sat at a spot.

Flashback

"Aaaaaaaaah!!!!!" You screamed as the 'tickle monster' chased you around. "Roar!" You laughed. "Mom! Help me!" "Oh I'm sorry sweetie! But I can't!" She laughed too as your father caught you and started tickling you. You screamed and laughed. You collapsed on the ground as your father stopped. "The tickle monster won! Hahaha!" Your father said as you giggled.

Another flashback...

You walked around with your parents again in here. You pointed to a crystal. "Mom! Dad! Look! A crystal!" You all went to it. You touched the crystal and it glowed. Your mom smiled and got the crystal. She poked a hole on it and put a string. She tied it and put it on you. The crystal glowed a bright (f/c). You smiled and hugged the both of them.

Flashbacks end...

Tears we're on your eyes. You missed them so much. You put your hands on your face and cried quietly. You spent a minute crying before wiping away your tears. You dug at your pocket to see the necklace. It can't fit on you anymore but you always kept it. You held it with both hands and used one of your thumb to gently rub it. It glowed a faint (f/c). You put it back in your pocket. A Firefly went to you and landed on your hand. You smiled and trapped it in, then you stood up then let it go. It flew with the other fireflies. You removed your jacket and stretched your wings. You touched them and then you flew. You gently and slowly flew with the fireflies. It was great. You spent minutes flying and you went to the ground. You stretched your wings again and then folded them. You got your jacket and put it on and zipped it. You went to the tunnel again and got your bike. You went back to your house. It was now 7:30. You parked your bike there and opened your house. You locked the door and got your jacket out. You ate a snack since you were still stuffed from spaghetti and then you went upstairs. You got in your room and lifted the bedsheets. You tucked yourself in your bed and you slowly fell asleep. You swore you saw your parent's there, smiling at you as you fell asleep but maybe that's just your imagination. You fell into a dreamless slumber.

Timeskip (sorry!)

It has been 10 months. It was december 13. Today is your birthday but no one knows it yet. You were at the skeleton brother's house. You were playing with frisk,Chara and asriel but, toriel​ went in and got them. She said it was time for them to go home. You looked at the clock. It was 7:00. You didn't noticed that until now. You waved them goodbye as they went out of the door. You smiled and went out of the house, after saying goodbye to the skeletons. You got your bike and went to the tunnel.

Sans's pov

I was sitting at the couch as (y/n) went out but I saw her phone. Huh. Must've forgot to get it. I grabbed it. "I'll go out pap!" "OKAY! BECAREFUL BROTHER!" I went out of the door to see (y/n) riding a bike. I flew and followed her without her noticing and then she went in a tunnel after parking her bike nearby. I went in and I saw a beautiful place. There were fireflies flying peacefully and there are some crystals growing on the ground. It looks beautiful. I watched (y/n) and she sat down at the grass.

Your pov

A couple of months ago, you discovered that you have powers. You have crystal powers but you haven't told anybody. You used your powers and summoned a crystal. You looked at it as it sounds on your hand. You made it dissapear. You took off your jacket and stretched your wings. You flew gently with the fireflies. You did tricks while flying and summoned some crystals and it does around with you. You gently went down back to the ground and stretched your wings. You folded them and got your jacket on. You heard clapping. You froze. They saw your wings... That isn't good... You turned around and saw sans. Your face was petrified. You were scared for your life. You gulped and flew up as fast as you can. You flew fast and you bumped into something. You looked up and saw sans. You forgot he can teleport. You flew everywhere but he keeps on teleporting right in front of you. You went back down, your wings tired. You gently folded them and whimpered as he walked closer. Is he going to experiment on me with alphys?!? You whimpered and dropped to your knees. You can't hurt sans because he is your best friend and you do have a crush on him. You felt your hands getting removed. You saw sans removing them. He put his finger on your chin and he made you look up at him. You closed your eyes and whimpered more. You accepted your fate and braced for the impact but, it didn't happen...? You opened one eye and sans was still there. "C'mon (y/n). Don't cry. I won't hurt you." You opened your other eye as he wiped your tears with his thumb. "Y-you- won't e-experiment on me...?" You said, still shivering. "Now, why would I do that to you?" " W-When I was a kid, s-scientists experimented o-on me and my p-parents." "No, I won't. You have beautiful wings. It's more beautiful than any other wings I have seen." He touched your wings which gave a shiver down your spine but you soon relaxed. "It's soft too." You looked at him. "Listen (y/n). I have, something to tell you." You tilted your head and he chuckled. "Anyways. I-its just... Look. I have feelings for you since I met you. You were kind,cute, beautiful," he sighed. "All i wanted to say is, i love you. You were my everything until now and you will forever be." You blushed a deep red. He loves you too? He grabbed your cheek and kissed you. You were shocked but you kissed back. That kiss was long and lovely but you two have to let go. "I love you too." You said and you two hugged. "By the way, happy birthday." You blushed. He knows?!?. "Heh. Thought I didn't know?" You two pulled away. You laid on his shoulder as you two watched the fireflies fly throughout the beautiful night sky. It was so peaceful. You felt hands around your stomach. You saw sans hugging you and pulling you close. You extended your arms to him and did the same. You didn't felt so loved before. Ever since your parents died, you didn't felt too loved but now, sans loves you and you love him back. You two stayed like that until you felt your eyes droop. You laid on his shoulder again and he laid his skull on your head. You fell asleep on his shoulder while he wrapped his wings around the both of you.
