Chapter Text
Hello everyone hoping you are having a good time. I felt like trying my hand out with one-shots. Having been inspired by the many different ones out there. Warning some of these might be cliche at heck, but they were inspired by whatever song I was listening to at the time, and I just felt like writing. Some will be me trying out things I haven't tried before. Like violence, maybe gore and various other things. Plus the multiverse since I adore the many various characters people have come up with for the well-loved characters of Undertale. I don't own anything except my writing, and will always try to credit any outside sources such as music, and anything that inspires me.
That being said for this first story I was listening to Eli Young Band - Crazy girl when inspiration hit. This is in the Underfell Universe with Fell Sans being our first poor victim. I hope you all enjoy!
Sans flinched as he heard the door slam shut. The last thing he heard was the sound of your sobbing, as you walked away from him. Clenching his fist he growled angrily as he closed his eye sockets. For a brief moment, he was tempted to follow after you. So he could tell you how stupid you were acting, and demand that you tell him why you were acting like you were, but he held himself back. You were like this because of him. He had messed up big time, and there was no one to blame except for himself. Turning away from the door, he opened his eye sockets and looked at the mess left over from the fight from earlier. There were broken dishes and glass everywhere. Flower petals seemed to have exploded all over the floor, and last, but not least was the remains of the dinner you had made him the night before.
His shoulders slumped as he took in the carnage. It shouldn't bother him as much as it was. He had seen worse. Hell in the underground it had been kill or be killed. He had killed for a living. There had been no mercy to be found until that damn kid had shown up, and began to change everything. He would admit he more then a few times had killed the damn kid himself, but thanks to their powers they would keep coming back. Each time with a smile, and refusing to fight back. Always showing mercy. By the time the monsters had been freed, they were well underway in their transformation. Sure it was rocky in the beginning and ok there were still some rough patches, but the kid continued to work with the monsters. The damn kid was far too smart for their own good, and soon it wasn't just monsters wrapped around their little fingers, but humans too. Without them, the two races would still be at each other's throat. If not for them he would have never met you.
When you came into his life, it was only cause, the kid had met you at the park and wanted to introduce you to all of their friends. The others and himself had been suspicious, but despite everything, you wouldn't allow them to scare you off. You kept hanging out with the kid. Which meant he had to deal with you since he and his bro were their bodyguards. Most of the people that met them might like them, but there were still assholes out there that wanted to cause trouble so at all times someone had to be watching the kid.
He tried to scare you off, first with displays of his powers. You were cautious but had been more amazed than scared. He tried to scare you off by being mean to you, but you fucking had the nerve to laugh at him and to add insult to injury you called him a rough tough cream puff. Nothing worked! He even started sneaking up on you and scaring you, but yes while you would jump, you would giggle afterward. At one point you got used to it and seemed to know when he was gonna pop up, turning just in time to say boo and stick out your tongue.
He found your weakness though. It had been an accident. He hadn't thought about it and flirted with you. Telling you that you had a sweet ass because you had accidentally sat on some of the kid's candy. Your cheeks turned the brightest shade of red, and you couldn't seem to speak. At some point, you took off. Then the game began. He messed with you every chance he got, and it seemed no matter what you would always blush. Even after all this time you still were easy to make blush. The thought made him chuckle half-heartedly. Thinking over the past, he began to clean up. Some of the memories made him smile, some caused a lecherous grin to appear on his lips. You weren't just easy to make blush. He would much rather have you beneath him, making those sweet sounds you only made for him as you held onto him tightly. A frown appeared on his face, as he thought over your tear-stained face as it forced away more pleasant memories.
How or when the game changed into something more serious he wasn't sure, but everyone else saw what was coming before he did. Hell, you even knew. You always seemed to know. You said you were just waiting on him. He blamed how you acted, on your main soul trait. You had more patience than anyone else he had ever met. It took him almost a year, but since then you had been with him. Not many people thoughts you two would work out, but four full years later and somehow you both were still together. Four years and a day he thought sadly. The day before was yall's anniversary. While you normally put up with his shit, lately you have been an emotional wreck. It didn't matter what he did it always seemed to be the wrong fucking thing.
He knew he was fucked up, and didn't deserve to be with you. He drank too much, was prone to fits of anger. Though he never laid a hand on you, he would always shortcut away and let off steam. He had a mouth like a sailor, and your parents weren't exactly thrilled that you were with him. While humans and monsters weren't at each other's throats they weren't exactly sitting around singing camp songs and making fucking friendship bracelets either. So you were constantly being harassed by other humans and a few monsters that thought it was sick that you were with him. Didn't help that he wasn't exactly a very popular monster in the underground.
Everything had begun to build up until he reached his breaking point. He forgot about yall's anniversary. Because the day before you had got pissed at him about leaving his mustard bottles on the coffee table in the front room, several in the kitchen and more than a few in the bedroom. He knew he was a slob. Never seemed to bother you before. Then out of nowhere, you couldn't stand the smell of mustard. You yelled at him and demanded he clean up after himself. He had popped off and said he would do it later he was tired. It was the wrong thing to say because the resulting fight forced him to leave the house before he did or said something he might regret.
Pissed off at you he went to Grillbys and got shitfaced drunk. Something he hadn't done in a long time. He passed out at the bar, and when he woke up he had one hell of a hangover. His body ached and he felt like shit. Didn't help he had fallen asleep slumped over the bar. Grillby surprisingly hadn't kicked him out the night before, and he woke up the bar being empty. The only thing that caught his attention was a note placed near his head. Telling him to check his phone. That was a cluster fuck if he ever saw one. He had several messages from his friends, but surprisingly none from you. Normally you would text him and apologize, but you hadn't even called him. When he checked over his friend's messages he felt his soul sink as they all wished him a Happy Anniversary.
Realizing he had fucked up he used a shortcut to the closest floral shop he could remember. He was in no shape to be pulling that kind of shit, but he somehow made it. He knew he scared the shit out of the human he suddenly appeared in front of, but luckily they were more than happy to give him what he wanted, to get him out of their shop before he did anything. Not that he would of, but they hadn't needed to know that.
Pausing he noticed a package on the ground. It was a simple black box with a red ribbon, with some bone charms hanging from it. Taped to it was a white envelope. Picking it up, he noticed his name written in your handwriting, with one of those stupid smiley faces you like to draw any time you wrote on anything. The package wasn't very big, but he could tell you had chosen it with him in mind. Frowning he sighed as his mind wandered back to what had happened when he had gotten home.
Using a shortcut to home wasn't as easy as the floral shop. He had planned to appear outside the door and maybe get back into your good grace with some knock-knock jokes. He knew they were bad, but no matter how angry you got. They always seemed to make you smile. Instead, he had ended up in the front room. Unsteady he had fallen back into a shelf causing it to rock and thanks to his fucked up state he couldn't get his magic to work right enough to stop the various items on the shelf from falling to the ground. More than a few shattering into little pieces.
Suddenly you were there. The fire in your eyes, normal would be arousing as hell, but at that moment that was the last thing on his mind as he noticed the tears streaming down your face. He tried to placate you. Giving you the flowers and apologized like crazy, but you wouldn't let it go. You even had the nerve to start ripping up the flowers he gave you and threw them to the ground. It kept going until he started getting pissed off. He understood he had fucked up, and yes he understood you made him a special dinner for yall's anniversary and wanted to make it up to him for being a bitch. He understood everything you were telling him. He wasn't fucking stupid! ........No, he was, but at the time the anger from the last while finally got to him. He yelled at you saying if you were so fucking miserable why don't you just fucking leave. The moment the words left his mouth he regretted it. Your eyes had widened. Disbelief and hurt were plain to see on your face. Followed by the devastation. The tears had increased ten folds. He tried to take back what he said, but you wouldn't listen. Refusing to let him anywhere near you. At some point, the tablecloth had snagged on his belt, and everything on the table fell to the floor. In a loud crash. When he tried to get closer to you as you made your way to the living room.
Freeing himself, he followed after you as you turned without a word and went to the door. He expected you to tell him to get out. He planned to do just that. The fight leaving him as the devastated look that had appeared on your face wouldn't leave his mind. He hated when you cried, but he had never seen that look before, and it chilled him down to the bone. You didn't stop though. You opened the door and walked out. He could only watch and listen as you cried. The door slamming had ended the sound, but the silence was worse.
So here he was staring at the gift you got him. He didn't deserve to open it, but he needed a distraction. Opening the card first. He rolled his eyes when he noticed a stupid cartoon skeleton on a motorcycle with the words ''Bone to be wild'' Above it. At any other time, it would of amuse him, but he wasn't in the mood. So he opened the card. Inside was some stupid generic card greetings, but below it was your writing.
'' Hey Bone daddy I know the last few months had been hard, and I am sorry. I just want to let you know. I love you more than anything in the world. That is no 'fibula'. Sans, I can't promise that for the next while that we aren't gonna fight. This will be a real 'test' of what is to come next, but I hope you like your gift, and that it helps you to understand why I have been acting how I have been.
I really do love you Sans. Love .......''
There was one of those stupid smiley faces at the end, but it looked like there was a pacifier in its mouth. Feeling like he was missing something, he placed the card on the table. Unsure he opened the small package to see some kind of paper folded up. Unfolding it he read over. His eye sockets widened. Reaching for his phone, he paused when he heard the doorknob begin to jiggle. The door opened up. He turned to see who it was, but he couldn't seem to move fast enough when he saw you there. You weren't looking at him. Arms wrapped around yourself. Like you were trying to be as small as possible.
A startled yelp escaped you when he picked you up and spun you around. Causing you to finally look at him in shock. He knew you had come back to apologize, but he wouldn't allow you to because when you opened your mouth to speak he pressed against your lips. You look like a mess. Your eyes puffy, and cheeks splotchy from your crying. Your hair was disheveled and all in all you most likely felt like crap, but he didn't care. He had fucked up and he would do everything in his power to make up for it. He should have realized something had been up when you started acting strangely.
He knew you were right, most likely you both would most likely fight in the future, but he would take anything you could dish out if you wouldn't leave him. He loved you and his soul felt like it was gonna burst with joy knowing that he was gonna have a family with you.
Until next time bye! <3
