***Hello, everyone! Honesty time: I've actually had this written for, like, two days. I wrote it at work on Monday (as well as the entirety of this story's plot line), and I was lazy like Sans yesterday (I won't lie), and I realized that I would never get this done if I didn't go on and get this chapter up. So, Sans, Papyrus, and Frisk belong to Toby Fox, and let's go!

Chapter One: I Walk A Lonely Road

At the age of eight was when Frisk faced the Underground.

Now, the fact that anyone had freed the monsters was astonishing, let alone it being a single little girl. But despite that, Frisk was still a kid. She lived with Toriel, and everntually Asgore, for the two had decided to give their relationship another chance.

But Frisk's home away from home was the residence of Sans and Papyrus. Frisk having sleepovers there was such a normality that eventually, Sans and Papyrus had just made it easier by turning a guest room that was doing nothing but gathering dust into a room for her. So, she was more or less a member of the household.

However, because Papyrus had to work more often, Sans was more involved in Frisk's life than his brother was. The two did everything together; went to the movies, had sleepovers, went swimming at the county pool, and much more.

It also was a practical advantage, their closeness to each other. Since Toriel was a teacher and Asgore ran a flower shop, Frisk didn't have a consistently-guaranteed ride home from school from either of them. But, Sans always showed up and brought Frisk home, staying at the house until Asgore or Toriel arrived.

At the age of thirteen, Frisk would just get dropped off at her house after school. And when she received her first car after turning sixteen, she didn't need to be driven or picked up anywhere.

After graduation, she began getting distant. Her life was taken over by college, looking for jobs, and her new friends. Sans was sad that his little buddy was out on her own, but he chalked it up to being a part of life.

At least he still had Papyrus.

However, even that was falling away from him. Like any other person, Papyrus had found his love. That love was Mettaton. After a year and a half of dating, Papyrus decided to move out and join Mettaton in his luxurious home.

And that left Sans all alone.

XxX

Sans laid across his couch, blowing smoke out from his mouth. He put the used cigarette in the ash tray on the coffee table—well, he attempted to. It missed and hit the floor, but it wasn't like he cared. That one would just join the rest of the trash in his floor.

He reached for a bottle on the floor—a bottle of whiskey, to be exact. He drank about half the bottle in one go before he plunked it back down on the ground. It was a good burn as it trailed down. He'd grown used to it, if the countless bottles of alcohol around his house and his tab to the liquar store meant anything.

He was about to go for another swig until he saw his phone light up on the coffee table. That was quite the anomaly... no one ever really contacted him any more.

So, he picked it up and saw that it was a text.

Hey, Sans. I'm working tonight and I think Papyrus is coming too, if you want to come eat dinner where I'm waitressing at.

The text was from Frisk. A slight smile came across Sans' face. Once he sent a text to confirm he was coming and got the details, he hauled himself up from the couch.

It looked like he needed a clean shirt.

***Yes, not much happened here. The next chapter should make up for what can only be known as a chapter to set things up, don't worry. And yes, Frisk is a girl, but that's not the main focus here. Anywyas, be sure to leave a review on the way out, and I'll see you all in the next one! Bye!
