Author's Note: Hey there! So this story is just one I write for fun and decided to publish so I can feel like I'm doing something with my life (lol).
As a side note- in this story, Papyrus doesn't talk in ALL CAPS (all the time) and Sans doesn't talk in no caps at all. Mostly because it bothers me. I hope it doesn't bother you guys? :)
Anyways, I have multiple chapters already written. I will release them ASAP, and continue writing because this is one of the things I am doing with my free time. I am looking over what I have written and deciding how to break them up into chapters as I go.
Thanks for reading!

CHAPTER I:You are filled with DETERMINATION

Frisk brushed her mousy brown short hair and straightened out her pink and blue striped jacket in the mirror. She carefully cleaned up a few things around the counter. Cleaning up after Papyrus and Sans became Frisk's autonomous hobby because Toriel let her sleep over so much. Ever since she "Saved Monsterkind" (as her generous Monster friends loved to put it), Frisk moved in with Toriel and Asgore in their expensive house in the Underground since Monsters found themselves more comfortable away from the Humans which saw them only as villains or sources of entertainment, with fascination being the least mean-spirited kind of entertainment. When they first arrived above ground, the Humans fortunately didn't attack them. They were kind out of pure fascination and interest until the general public saw them as topics to discuss on talk shows or put on stage as jokes.

The Human's leap to using Monsters as a source of entertainment made the Monster dream to return above ground die quickly. Monsters soon saw Humans the same way the Humans saw them. Nothing more than something 'new' and 'different'. Everyone stuck to the places they were before, with the exception of a few outliers, and the fact that tourism slowly brought the two species closer. Snowdin was practically a human tourism city now, due to its cozy feel and location close to the capital. The tourists were usually kind and respectful, and it didn't take long to realize that the Humans themselves weren't much different from Monsters.

But to Frisk, none of this mattered. She spent more of a happy life with the Monsters, and that made her feel closer to them than Humans. So in short, she only cared for her life in the Underground with her family and friends; and the drive to her skeleton friends house in Snowdin wasn't too far from the monster capitol she now resided in. Even though Frisk was getting older than a teen now, they still treated her like their innocent little teenaged girl.

This evening, on a Saturday, Frisk woke up late as usual.

Papyrus was already in the kitchen 'cooking' something spaghetti-like.

"Hey Papyrus!" Frisk smiled, waving as she walked into the living room and took a seat on the couch.

"Hello, precious human!" He shouted excitedly as usual. "Would you like to join me in my spaghetti tasting?!"

"Sure." She nodded. It was funny to her that Papyrus was so blithe and there was nothing awkward between them despite that strange date they had ages ago that Frisk pushed to distract him from fighting her.

If Frisk wasn't spending her time being homeschooled by Toriel, she was helping Papyrus with something dumb or doing something even dumber with Sans. But she enjoyed it. They made her laugh and it made hanging out with girls like Undyne and Alphys refreshing. Of course, Mettaton was fabulous to hang out with, too, but he was always trying to dress her up or get her on a date with someone.

Suddenly, as Papyrus was fixing her a plate of Spaghetti, Sans walked through the door.

"Hey, kiddo." He smiled at Frisk.

Sans was always just coming out of nowhere and no one ever asked anything. Frisk always thought, at first, that it had something to do with all the weird jobs he had, but she knew better now. She never talked about it, though.

As Papyrus placed the plate down for her, Sans brought something up to her.

"Hey, ya know, I was thinking about something, recently…" He spoke.

Frisk just listened and ate her semi-edible spaghetti.

"I was thinking that you need to learn to defend yourself."

"Oh…" Frisk sighed. This wasn't the first time Sans or one of her friends tried to tell her she needed to defend herself by fighting back, instead.

Frisk never fought anyone. She was too sweet and silent to do so.

But this time, Sans was serious. If that was even possible for Sans.

"So i'm gonna teach you to fight back today." He said, sounding determined.

She gave another sigh, spinning her fork in her spaghetti.

"I know ya don't wanna, kid. But some day you're gonna have to defend yourself. You won't be a kid forever." Sans said sincerely.

"I'm not a kid." The mute girl huffed.

Papyrus jumped to her; "But look at you, you're still so adorably tiny!"

"C'mon." Sans offered her a hand out of his pocket and pulled Frisk up off the couch. The two shuffled outside into the Snowdin snow and Sans turned to her.

"Okay kid. I want you to fight me. And no crap this time. You can't distract me the way you did everyone else." Sans smiled, still.

Frisk's face went pale.

"F-fight you? You mean you want me to throw a punch at you?" Frisk looked big-eyed.

Sans simply nodded.

"I'm not gonna do that!" Frisk spoke slightly louder than her usually quiet voice.

"Well you're gonna have to. Cause I'm gonna fight you back and it's gonna hurt unless you defend yourself." Sans threatened seriously, his left eye glowing in a blue fire that frightened Frisk.

"Ready?"

Frisk shook her head 'no', but Sans took a hand out of his pocket anyways.

He flung a fiery blast her way, and Frisk tumbled over to avoid it.

"I'm not gonna fight you, idiot!" Frisk shouted, for once. She was mostly perturbed.

She finally decided that she had to break out the big guns to get out of this one. She had to do it the Papyrus way- times two.

Sans began to fling another attack, glowing blue eye and all until he saw Frisk get up like she was going to do or say something important. He was hoping she was going to throw a punch but instead…

"G-go on a date with me!" Frisk screamed, her face blushing red as she looked away from the skeleton.

Sans stopped immediately and put his hand back into his pocket again. His face seemed strange.

"Hah...hah…" He laughed "...This kid… Heheh…" He seemed to stress.

"You're funny, but I won't fall for that. You aren't getting outta this."

Frisk groaned.

"I mean, geez Frisk I thought you knew me. I'm like the total opposite of a calendar." He stated. smirking.

"W-what…?" Frisk just stood there, still blushing and wondering what the heck Sans was talking about.

"I don't ever have any dates." He explained.

"Oh." Frisk snorted, laughing for a moment, realizing that she didn't pick up that it was just another one of San's puns.

"W-well i'm not giving up!" Frisk declared, sounding determined despite the fact that she was laughing, which made Sans smile wide.

"Besides, I have plenty of qualities that make me eligible as a date for you!"

Sans just stood there, sincerely wondering what Frisk was trying to do with this.

"Kid…" Sans laughed a little, looking freaked out to say the least.

"Let's just go to the Library. It'll make this whole thing a lot easier." Frisk smiled to the confused looking Sans.

"What..? Why?"

"Because i've been trying to check you out!" Frisk laughed evilly, as if Sans fell right into her evil trap. Despite the fact that she was technically hitting on him.

"Oh..dang...kid….you're such a nerd!" Sans facepalmed and he finally fell, laughing like crazy. Frisk stood proudly. She defeated Sans. She knew she could do it.

Something about her loved the whole idea of actually flustering Sans and making him laugh. In fact, this whole thing began a new trend with Frisk.

The whole week, Frisk kept making innuendo puns at Sans that kept making the skeleton freak out at first and then break out into laughter. Frisk had never seen such a reaction from Sans and she enjoyed it.

Eventually she got used to doing it even in front of others. On a Friday afternoon when she was at the skelebros' house for dinner, Frisk used another one. She loved getting on his nerves about the whole date idea. It kept him from ever bothering her about fighting people again.

"Hey...feel this shirt...what do you think it's made of?" Frisk pulled her shirt out in Sans' direction.

"I dunno." Sans looked confused, but seemed to expect something.

"'Cause it feels like girlfriend material to me."

"OH MY GOD SANS!" Papyrus somehow still got angry at Sans, despite the fact that Frisk told this one.

"Not only are you teaching our human to use these horrible puns-!" Papyrus grumbled at Sans. "But you also have got her hitting on us!"

"Yeah, what's up with you kiddo? I told you the date thing isn't happening." Sans turned to Frisk.

"I've already dated Papyrus!" Frisk stated; "So it's only fair that I date you, too."

"A date with Sans?!" Papyrus practically howled with laughter; "Human! That sounds so boring! Nyeheheheheh!" He laughed, as if what she was saying were scandalous.

"Yeah. It'd be pretty boring, Frisk." Sans nodded.

"No it wouldn't! It'd be fun." Frisk insisted with her normal faint smile.

Sans looked tortured; "You're not gonna stop bothering me until I take you on a date, huh?" he guessed.

Frisk just nodded as she ate her dinner.

"Okay, fine. We'll...go on a date."

"Oh, finally. I mean I know you're feet must hurt after this week." Frisk grinned.

"What? Why would his feet hurt?" Papyrus asked, very, very loudly.

"Because he's been running through my mind all week." Frisk grinned even more.

"OH NO SANS LOOK WHAT YOU'VE DONE TO HER!" Papyrus yelled at Sans angrily about the pun but he was busy laughing.

"Okay, friend, you've earned that date." Sans winked at Frisk. "Anyone able to tell puns that bad is maybe just bad enough to date me."

Frisk giggled and gave a cute smile.

After the next few days, Frisk eventually got Sans, lazy as he was, to give in on the date he promised.

"Okay, but I'm you're gonna have to tear me away from work." Sans joked and Frisk just rolled her eyes at this.

He took her to...Grillby's.

"Sans. This isn't a date this is just you and me hanging out." Frisk practically laughed.

"No it isn't. I didn't whoopee cushion you." Sans stated.

"Oh. How gentlemanly." Frisk snorted, realizing he was right. He usually did that.

"Besides, going on a date is basically just hanging out anyways, right?" He winked.

Frisk just shrugged; "I guess so."

"But can we at least sit somewhere diff-?" Frisk began to criticize that they sat in the same place, but looked around and realized they weren't.

I could have sworn we sat in the same place as usual!... Frisk thought to herself, feeling crazy.

"What's that?" Sans grinned normally.

"Oh? N-nothing…" Frisk blushed, feeling weird now.

They sat, talking and joking around as they normally did together. Today in Snowdin was colder than the normal already-cold days. Today- even Grillby's was a bit chilly.

"Brrr…" Frisk began to cross her arms, but noticed Sans' jacket was on her shoulders.

WHEN DID THAT GET THERE?! Frisk felt like she was going insane.

"Getting cold?" Sans grinned.

"Wait a minute…" Frisk narrowed her stare on Sans, "Are you dating me through time and space?!"

"Huh?" Sans played stupid.

"Don't play dumb! I know you're doing it…" Frisk hissed playfully. Frisk never knew Sans to use his strange affinity of time and space for something like a date, but…

"I'm not playin' dumb! I dunno what you're talking about." Sans shrugged, still smiling.

The adorable and shivering Frisk simply let it go and decided she'd catch him in the act in another way.

"You still seem cold, kiddo. Maybe we should go back home…" Sans suggested, noticing her still-shivering body.

Frisk just shook her head.

The idea of anyone having an actual successful date with Sans filled Frisk with determination.

Next thing they knew, Undyne and Alphys were walking through the door and they suddenly spotted Frisk.

"Oh~! Frisk! H-hey!" Alphys waved in a whirl of excitement. The two walked over to their booth.

"Hey, Undyne! Hey, Alphys!" the human smiled brightly, reflecting the light that contagiously spread happy feelings around everyone she met.

"Frisk! You're- so adorable in Sans' jacket!" Undyne spat out. Alphys and her were practically fangirling over Frisk as if she were still the only human they'd ever met.

"Oh-oh my god…" Alphys grabbed onto Undyne and poked at her; "I think th-they're on a date…" She whispered to the fish girl, but Frisk could hear it.

A blush broke across Frisk's fair face. She brushed her brown hair out of her face and bit her lip, not knowing how to respond to Alphys talking about her.

Should she tell them?

"No way...My best friend could do way better!" Undyne exclaimed quite loudly, since they figured Sans hadn't heard what Alphys said. Which may have been correct since he looked totally unphased. Or Sans chose to pretend he didn't hear it.

Alphys whispered in her ear again; "N-no! They are! Just look at Frisk's body language! I've read about this in fanfic."

Frisk blushed practically pink, now.

"B-but he looks totally normal." Undyne rebuttled in whisper.

"Uhh… Are they havin' their own conversation over there?" Sans talked to Frisk.

"Uhm...I think so." Frisk blushed some more due to the pure awkwardness of her friends.

The two were so busy in their own topic that they didn't even notice Sans' comment.

"You're joking right? He's totally a tsundere! He just doesn't want to look like he cares." Alphys was whispering back.

"Hmm..he doesn't seem the tsun type. But maybe Sans is just too lazy to look like he has feelings." Undyne responded.

Their whispers were so loud now, Sans and Frisk were both practically in their conversation.

"Yeah, that's pretty accurate." Sans agreed on their commentary, scaring the living hell out of Undyne and Alphys both.

Frisk could tell Sans answered just to see Undyne and Alphys get scared from him hearing.

"Yeah. The kiddo wouldn't stop berrading me with innuendos all week until I went on a date with her, so I did." Sans explained.

"Oh, really?" Alphys and Undyne both said, as if they'd never expected Frisk to like him.

Alphys turned worriedly and Frisk was confused by her concerned face. For some reason… It meant so much more than any of the comments she'd made in conversation with Undyne. What was it that made her look so worried for Frisk?

"W-well, uh, I guess we'll leave you two to your…" Alphys couldn't finish the sentence she seemed so weirded out.

"Date." Frisk whispered in her usual shy voice.

"Yeah." Undyne nodded, and the two left to their own date.

Frisk continued on with the date, laughing and talking to Sans in no way different than usual, but for some reason Frisk could tell he was holding back on something.

As they walked back to Sans' and Papyrus' house in Snowdin, Frisk made a face that let Sans know that she knew he was acting strange.

"Ah...you caught on." Sans gave in.

They stopped outside the little snow-covered house.

"Look, here's the thing Frisk…" Sans opened up just a little bit more, but Frisk could tell he was still holding back. "I treated you terribly on that date, and you still kept leading me on."

Frisk blushed at this. What did that mean? Was he testing her the whole time? Frisk didn't like being secretly tested like she was some human psychological experiment. She'd already had experience with that.

"The point is- I was trying to keep you from wanting to actually have this date but you still seemed to want to. You need to learn what kinda guys you deserve." Sans laughed a bit, looking a little embarrassed that he had to get into this conversation like a father would with his daughter. "You should never keep going with a guy who treats ya like that."

"What do you mean? You treated me perfectly fine." Frisk blushed, wanting to cry that Sans wouldn't let her just have this one date and take it seriously instead of as a lesson to her. She could feel the rejection coming on from him.

"I took you to Grillby's. Then I proceeded to nap for a while and I didn't have any real conversation with you other than my bad jokes." Sans' practically laughed at Frisk's denial of how he treated her, but she was stubborn.

"So? That's not what a date's about!" Frisk blushed.

"Hm. Well I'm trying to say… A first date is a guy trying to prove something to you. Maybe because we know each other...it's a little bit different, but…"

Frisk interrupted; "You did prove something! You proved that you were still your stupid lazy and comical self and that's all I need. I don't wanna go to a fancy restaurant with some guy and talk about boring stuff. I can do that in the Overworld with a human guy any day." Frisk crossed her arms heroically.

Sans could see the stubborn determination in her eyes.

"We're gonna go on another date! And this time- no psychological experiments! Just you and me, somewhere alone this time so our friends don't bother us." Frisk demanded.

"Oh geez...Frisk…" Sans gave a sigh, seeing she wouldn't see it any differently.

"Tomorrow!" Frisk stated, and with a second sigh from Sans, they walked inside to hang out and watch TV with Papyrus.
