Before the Barrier fell, October never meant much to Sans. It was just one more shitty month in the year— the weather never changed Underground, so it held little meaning to him. Now, one year later, October had changed entirely. For one, October meant autumn on the surface, and Ebott being a mountain town meant it got hit hard by fall. The leaves all changed and fell, the wind grew colder, and days grew shorter. But setting the natural world aside, October went from being one month among many to being the busiest goddamn time of the year. Firstly, Frisk's birthday happened in the middle of the month. One week after that was the very first celebration of Monster Liberation and that whole mess that consumed their schedules. After that, it was Halloween and after that was Dia de Los Muertos both of which Frisk observed which meant that he, Papyrus, and the kids ended up joining in as well. They'd even gone to an amusement park in all that as a belated birthday celebration for Frisk.

So about halfway through all that running around, Sans had begun to dream of the end of October and the beginning of November the way human children look forward to Christmas. Once all the celebrations had ended, Sans was happy to collapse into his chair and enjoy the peace and quiet. There was some sort of human holiday at the end of the month— Thanksgiving? Friendsgiving? Black Friday? He couldn't be bothered to remember the name— but that was at the end of the month, so might as well enjoy the quiet while he could.

And he had been doing just that for a whole week before Frisk paused one night as they were climbing into bed to look at him. "Hey. Last year, when did we move into the house in New Home?"

Sans blinked, looking away from the book he'd been reading to stare back at them. "Uh, the tenth, I guess. Why?"

They were silent as they finished climbing into bed and getting themselves situated before turning to look at them. "So, the tenth you said?"

He squinted at them, hesitating to speak. "Yes…?"

"Alright then." They smirked. "That makes it our wedding anniversary."

Sans flinched, the lights in his eyes going out as he felt a proverbial bucket of cold water go down his back. "Oh."

"Yeah," they continued. "But you know, I was thinking."

He got the uncomfortable feeling that he had no idea where the hell they were leading him with all this. Still, he felt sheepish enough to go along with it. "Uh, yeah?"

"Mmhmm. Having another anniversary so soon after everything is kind of a pain, right?"

Sans blinked. Was… was this some sort of trap? Why the hell were they wording it like this? Should he answer honestly or lie? After a moment of consideration, he nodded. "I guess so?"

"Alright then. So, if anyone asks, we'll just say it's in late July. That's when we moved to the Surface and that's not too long before I found out anyway. How's that sound?"

Sans froze again. Either this was an out or a trap. Or a joke— actually, yeah, that sounded about right. Frisk was just playing a prank on him; god, he should have seen that earlier. Still, he didn't quite relax just yet. "That's… fine by me."

They nodded. "Fantastic." And with that, they flopped back onto their pillow. "Hey, you mind if we turn off the overhead?" they asked, gesturing up to the overhead ceiling fan, whose lights were currently on. "You can keep your bedside light on if you want to keep reading."

Sans glanced at the book still in his hand. They were changing the subject, so this definitely seemed like a silly joke they were playing on him. Yes, it had to be a prank. God, they'd scared the shit out of him for a second. Biting back a chuckle, he shook his head and dropped the book off his side of the bed. "Nah, I'm good."

"Cool. Mind hitting the lights then?"

"Got it." With a flick of his finger, he used a bit of magic to pull the switch down from across the room, sending the room into darkness. As he wriggled down, under the covers, he felt one of Frisk's hands plop down across his chest. Not pushing or tugging, just lying there, slowly curling into the folds of his shirt. Amused and bemused at once, he patted their hand, mostly to see if it would prompt them to say something, but instead they just curled their fingers more, anchoring their hand to the spot.

Heh. They were in a weird mood tonight. Well, whatever. He'd dealt with far more obnoxious bedmates than them. Besides, he had to admit, the weight was oddly reassuring, a physical connection to remind him he wasn't alone in the dark.

Still had no idea what wild hair crawled up their ass to prompt this, but whatever.

However, they weren't quite done with him yet. Just as he was starting to drift off, he heard their voice, clear as a bell. "By the way, you still owe me a honeymoon. We can do that instead of an anniversary and I'll let you off the hook."

His eye sockets flew back open and he waited, but they remained silent. At a loss, he shrugged. "Uh. Okay."

"Great," they replied and fell silent again.

Sans stared up at the dark ceiling thinking okay, I don't think this is a prank anymore.

Despite the abrupt notice, Sans wasn't actually annoyed by the idea of a honeymoon. After some thought, he was back to thinking that it was probably mostly a joke on Frisk's part, but on the other hand, well, he had pretty much botched everything to do with telling them they were kinda accidentally married. Aside from some yelling and a lot of grumbling during that one day they got a little drunk at Grillby's and then came home and talked about it, Frisk seemed to have mostly taken the whole marriage thing in stride. They hadn't even hit him, which he probably deserved on principle. Their relationship hadn't really changed either. Now Frisk mostly just teased him about the fact they were (technically) married. So, if nothing, he felt like he owed them some sort of apology or thank you gift for being so sporting about the whole thing.

The only problem is he had no fucking idea what humans actually did on honeymoons. Monsters stopped having wedding ceremonies decades ago, but he wasn't sure that honeymoons had ever been a popular thing with monsters anyway and, if it had been, it definitely wasn't a thing now. Sure, he had the basic idea of what a honeymoon was—there was enough human media for monsters to get the gist of it at least. That it was something a married couple did after getting married, usually involving running off somewhere and fucking like rabbits.

Two things that neither of them minded in the least. So, theoretically, he had no reason to object to it. Mainly, the problem was he couldn't ask the one person he always asked when it came to human shit, namely Frisk. It felt like asking them would be awkwardly admitting defeat. However, the next person he knew that would know all about human culture would be Chara, and he would literally happily eat his own coat, buckles, zippers, and all before he asked that little shit question one about anything. Toriel might have known something about the human concept of honeymoons once, but after a couple thousand years stuck underground, she probably wasn't up to date on that shit.

That left Alphys.

Which meant he completely gave up on asking any one person and just got on a computer and looked it up himself. Cause there was no way in hell he was asking her about that—she was still ribbing him about keeping the marriage a secret from Frisk in the first place. At least the internet didn't fail him and he quickly got an idea of what humans did after their weddings, and it was just about what he'd thought in the first place. Humans had a wedding ceremony, apparently got drunk to the gills, went somewhere else, and then fucked like rabbits.

Mainly, however, when they went somewhere else, these places seemed to be expensive as fuck and far away as fuck. Lots of people seemed to want to go to Hawai'i, Paris, or Tokyo, or go on a cruise. Which might be nice for some people, but Frisk hadn't exactly given him a budget, so he wanted to keep it cheap, and also he didn't want to go fucking anywhere if could get away with. If Frisk wanted to get drunk and fuck, fucking sweet. If they thought he was going to be shelling out a couple hundred grand on some stupid trip, then…

Well. He did kinda owe them something nice. Still, he decided, it'd be better if it was to some place he'd already been to so he could just teleport there and back, to at least save traveling costs. And, with Frisk's job forcing them to travel around, that actually left them a decent amount of places he could take them.

They'd given him a tough, weird job, probably as prank, but fuck if he wasn't going to do it. Hell, it might be nice to take a one day vacation, so why not?

Too bad he was about as romantic as a wet sock.

Fuck. Maybe he should ask Toriel at least. Or would that be cheating?

No. He could do this. After all, he had internet access, teleportation magic, and enough money to probably figure out something good. He could do it. After all, what was Frisk going to do?

Divorce him?

Hm.

Maybe he would ask Toriel. Just to be safe.

One week later, when Frisk shoved a cup of coffee at him, he took a pull from it and then turned to look at them. "Hey. You weren't planning anything today, right?"

They blinked at him. "Other than maybe going down to Grillby's for a hamburger and beer? Not much."

"Great. That'll work out just fine then."

They shifted in their chair to stare at him with narrowed eyes. "Oh, will it now?"

"Yep."

"Okay, I'll bite. Why will my going to Grillby's work out just fine?"

"Cause that means you have plenty of free time."

They considered him thoughtfully from over the top of their coffee. They slurped as they stared. "That's not incorrect, I guess. What exactly do you have planned that I need to keep my day free?"

Well, he should probably just let the other shoe drop before they got too suspicious and stopped being willing to play along. "Well, you were the one who kept going on about a honeymoon. I just figured we could get it over with today."

Immediately, they huffed a laugh—not necessarily a mirthful sound, more like disbelieving. He'd expected it. "A honeymoon? What, you planned something out in, what, two days? And it'll only take one day?"

Oh yeah. He'd forgotten that a lot of the things he'd read said humans took awhile to enjoy their honeymoons. Well, never mind that. "We're busy people," he retorted, waving the concern off. "We don't have time to fuck around with a weeklong trip or something. One day's all we need."

That time, they really did laugh. "How romantic! Alright, fine. What exactly are we doing on this honeymoon, or am I not allowed to know that?"

He smirked. "I think I'll give you the general idea. First, we're going somewhere tropically warm."

Their brows shot up. "Really."

"You think I'm lying?"

Their mouth trembled as they bit back a grin. "No, forgive me. Please go on."

"Alright, after that we'll be going out for our own private wine tasting."

"Fancy!" they managed after a moment. "Sounds like a busy day. What's next after that? Dancing? A cruise?"

"I'm thinking a planetarium. I think I'll deserve it by then."

They didn't bother to hide their back of laughter. "Okay, actually, I can see that one easy enough. Alright, skeleton man, you have my curiosity. When are we going?"

"Eh. Whenever we get dressed, I guess."

Snorting, they stood, picking their cup up to set it in the sink. "Well then, guess I better go get ready. Should I dress up, or is this a casual affair today?"

"You knock yourself out, but I sure ain't."

They laughed as they walked out of the kitchen. "Noted."

After awhile, they returned to the kitchen, dressed in casual but clean and neat clothing. Unfortunately, he wasn't dressed half so nice with the baggy t-shirt and boxers he'd worn to bed, so they had to half bully him into changing clothes.

Once they got him mostly presentable, they asked him just how they were getting to these places. Wordlessly, he offered them his arm. As soon as they tucked their hand into the crook of his arm, he teleported them away.

Gravel crunched under their feet, making Frisk look down as their feet shifted, so they missed their first look at their location until they were steady again. Once they looked up, they paused and closed their eyes, blocking the view once more and wondering quietly to themselves whether to laugh or groan.

"Someplace tropical, huh?" they asked, turned to look at him. They couldn't quite manage a glare, but they think they at least looked a little annoyed.

Or maybe not; Sans didn't seem particularly fazed as he gestured to the botanical garden's greenhouses before them. "Tropically warm. I remembered when you and Pap took the kids here back in August and how god forsakenly warm it was in there. I'd call that tropically warm." What did it matter that the botanical garden was only about ten minutes away from Ebott? It was at least out of town.

"You're a fucking smartass," they chuckled. "But, you know, I saw somewhere that they have some really old bonsai trees on exhibit and they're supposed to be really neat. I guess I can finally go see them."

"Hell yeah. You can go look at tiny ass trees," he said as they started walking forward.

They gave him a long look. "I can go look? What exactly will you be doing in the meantime?"

"Isn't obvious? I'm going to go take a nap. These hothouses always make me sleepy. Oh, look, I can see a bench from here. See you late-"

"Oh, no, you don't." They reached out and snagged his arm, tucking it against their own as they pulled him forward, towards the greenhouses. "This might be a cheap honeymoon, but it's ours, so no napping just yet!"

"Ugh, fine."

They didn't look they believed his faked annoyance in the slightest and instead proceeded to lead him along. They at least headed towards the warmer greenhouses, not that they had to do much forcing. True, he didn't give much of a damn about plants, but they seemed happy enough. They pointed out the ones they thought would interest him—mostly the gnarly ones that were either carnivorous or surprisingly poisonous.

After the two of them finally found the collection of bonsai trees Frisk had been talking about, Sans had started eyeing the nearby bench. It looked like a decent enough place to get some sleep. Too bad for him, Frisk caught him eyeing the bench longingly and laughed.

"Okay, lazy bum. It's almost lunch, so how about we get going to this 'wine tasting' you set up for us." They patted one of his shoulders. "You can sit there as much as you want."

He relaxed. "Eh, that's not a half bad idea."

"I'd like to think I manage a few good ones from time to time."

Chuckling, he reached out and snaked an arm around their waist and teleported them away, grinning at their tiny squeak of surprise. Once they were at their new destination, he let go and had to close his eyes so he wouldn't smirk at the look on their face.

Frisk, for their own part, looked around at the new surroundings and almost managed a scowl as they looked back down at Sans. "This is Grillby's."

"Oh. So it is."

"This," they paused, trying desperately not to laugh. "It's, uh, not exactly a winery, is it."

"Eh, well, it was going to be wine tasting, but you mentioned hamburgers at Grillby's, so I decided it'll be a beer tasting instead."

They lost the fight and barked out a laugh. "You cheap son of a bitch!"

"Nonsense. I don't even have a mother."

They had to press a hand to their mouth to smother as much as the laughter spilling out as they could. They were already getting a few bemused looks from Grillby and the few customers that had showed up for lunch. After a struggle, they fought their laughter down enough to keep a mostly straight face as they turned to walk to the bar, but not before they got one last remark in. "You're paying your own tab for once."

"Harsh. Babe, this is our honeymoon. You should be nicer."

Rather than answer that—which they couldn't have without hurting themself laughing—they waved Grillby over. "Grillby, did you know Sans was a true romantic?"

"Oh god," he muttered, quickly looking away and pretending that he was searching for a mustard bottle. Of course, Grillby had taken to hiding them on him, but sometimes Grillby's daughter or his worker would forget and leave it out. The bottles, however, were missing this time and he had nothing to hide behind as the fire elemental arched what he assumed was a fiery eyebrow.

"No, it's true, Grillby. You see, our good friend Sans's has finally made good and took me on our honeymoon."

Grillby shot the two of them a disbelieving look.

"Yes, I know. He even came up with everything himself and I've just been along for the ride. Why, he even took me to a 'tropical paradise'. Didn't you, Sans?"

Fuck, maybe this was why humans took their partners faraway—at least they wouldn't be able to mock their spouses during the actual trip. "Tropically warm."

Frisk shrugged and leaned forward conspiratorially. "He took me to the botanical gardens out of town."

Grillby did not look surprised in the least, that bastard.

"And now, we're going wine tasting," Frisk went on before putting one elbow on the bar. "Now, I know you must be wondering. If they're supposed to be going to wine tasting, what are they doing here? Well, I'll tell you. Sans, here," they paused to toss an arm around his shoulders. He wished he could sink into his coat like a turtle retreating into its shell; instead, he managed a grin. "He decided beer and burgers would be better! So, Grillby, I'm going to need a couple bottles of your finest beer and a couple burgs, if you'd please. Oh! And," they gave his shoulder another squeeze, "Sans has offered to pay it off along with the rest of his tab."

Grillby put a hand to his chest, his eyes comically wide.

"I know. The height of romance."

Grillby nodded and then vanished back into the kitchen; the moment he disappeared, Sans cleared his throat. "Go eat a dick."

Frisk let go of his shoulders to wave him off. "Eh, I've been thinking of going vegan, so I'll pass."

"You literally just ordered yourself a hamburger."

Frisk blinked. "Oh, damn." They turned to him with a grin and began to elbow him in the arm. "Guess I know what I'll be have for desert later then, eh?"

This is my spouse. He snorted. "Ya nasty."

"Yeah, well, you married me, so joke's on you."

"It always is."

The two of them kept teasing and prodding each other until Grillby came out with their food. He served them and then got them a pair of what Frisk knew for goddamn sure was not even the best beer on tap, let alone in the bottles.

"Still," they murmured, taking a bite out of their burger, "I'll admit it. This burger is just as good as any wine I've ever had."

"See? I'm full of good ideas."

"Oh, you're full of something," they snorted, setting their burger down so they could reach for their beer.

Grillby, who happened to be passing by, surprised them by speaking. "Shit, probably."

Sans watched him walk away, expression full of mock offense while Frisk nearly choked on their swig of beer. He had to thump them between the shoulder blades before they could catch their breath. "Well, eat fast because we're getting out of here before he has time to come back with the tab."

Frisk almost choked again, this time on air alone. "You are," they hacked, "a real piece of work. Okay, fine, we'll dine and dash. Will we be heading directly to the—"planetarium" or will we be going anywhere else first?"

Sans considered it. Actually, they did have a little time they could kill before they had to move on to the last item on the agenda. Well, might as well let them pick something to do. "If you got something in mind, I wouldn't say no."

"Fine. I want to go down to Muffet's and get a cheesecake. I've been craving some for going on a week now and since it's our honeymoon, I believe I should get to indulge a little."

Oh. Cheesecake. That did sound nice. "Fine by me. Now, lean over here before-"

Too late. Before he could even finish his sentence, Grillby appeared and nearly smacked him with the tablet that had his tab on it. Frisk laughed at him while he grumbled and fished out his card to pay his tab. Once that was done, the two left, Frisk still waving goodbye as they vanished from the bar to right outside Muffet's bakery.

Sans was glad to slump into a chair while Frisk went up and got them a cheesecake. For being a pretty frosty bitch, he had to admit that the spider leader did know how to make some mean treats—emphasis on mean since sometimes Muffet would give poisoned treats to monsters. It was debatable whether she did it randomly, as revenge, or for her own amusement, but Sans was still a little confused on how popular the spider wares were.

Soon enough, Frisk was walking back to him, box of questionable but tasty cheesecake in hand. "Okay, hot shot. Let's see this planetarium of yours—once we drop this off at home, okay?"

"Well, it won't be out of the way," he said as he got up which made Frisk squint at him. Rather than give them time to question him, he offered them his hand.

They took the hand, blinked, and found they were already in the kitchen. Taking a step back, they held up the cake. "Are we in a hurry or do you want to have a bit of desert before we go?"

"Eh, yeah, sure." He shrugged, already turning and heading for the living room doorway. "I'll be upstairs when you need me."

Frisk watched him go, eyeing him suspiciously before they got the cake cut up and then put in the fridge. They got them and him a slice each, grabbed some utensils, and headed for the stairs. He was up to something in their bedroom, they could hear him rummaging around as they climbed the stair. Oh god, what's he gotten into now? "Sans? You okay in there?"

"Give me a minute!"

They paused, still a step or two away from being able to peek into the doorframe and see what the hell he was getting up to in there. "…okay? You're not, like, building a bomb in there are you?" They smiled at their own silliness. "Cause, I already told Chara no, so I can't let you do it either."

"What was that little freak going to do with that anyway? Anyway, just—give me—…okay. You can come in now."

Raising a brow, they took the last few steps and turned to look. This time, both brows went up. "Wow. You built a tent out of blankets." They paused to consider it. "It looks nice." They looked at him from where he was laying half hidden under the draping fabric. "I have to say, you've put a lot of effort into today. I'm very impressed."

"Well, you should be, you sarcastic little shit."

Chuckling, they walked over and ducked to hand him the plates. He took them without prompting. They got down and scooted in as gracefully as they could, which was more gracefully than most would have expected of them. "Okay, but really. You really got it all set up nice in here. The nice pillows and blankets and everything. Very comfy." They happily flopped down and took their plate and fork back.

"So, you like it?"

"Yes, I do."

"Good," he nodded. "Cause I ain't changing it now." He grinned as they nearly choked on their first bite.

"This is," they managed, "the most "romantic" honeymoon I've ever heard of."

"I can literally see the quote marks you put around that," he informed them, getting his own bite of cake. "Okay, this is pretty good."

Chuckling, they admired their next forkful. "It is. But you know, what would make this better is that bottle of red wine we got chilling in the fridge."

"Uh, yeah, the robot gave that to Pap, so if you want to break it open, you'll be taking the heat for that one. Also, I ain't getting out of here now, especially not for forbidden wine."

Snicker at the thought of 'forbidden wine' Frisk shook their head and took the bite anyway. "Alright, smartass, I do have one question left. When are we supposed to be going to this 'planetarium'?"

Sans held up one finger and then reached casually over his shoulder to poke something above his head. Instantly, cartoonish stars appeared on the blanket roof above them, rotating slowly.

Frisk gawked upward for a moment before a bark of laughter escaped their mouth. They clapped one hand to their mouth and tried to glare at him. "You—you stole that from Asriel."

"What, it's not like he's here to use it."

They snorted and tried desperately not to dissolve into giggles. "Oh, and the lullaby tune was also supposed to be part of the aesthetic?"

He shrugged, eating his cake. "Well, it doesn't hurt it now, does it?"

They lost the battle to their laughter and nearly howled. "How—how romantic," they squeaked between gales of laughter, "you're—you're trying to put me to—to sleep? In our cheap ass plan—planetarium?"

"In our fantastic planetarium, thanks," he retorted.

Frisk laughed but then yelped in horror as they accidentally dumped their plate off their stomach to land in a mess among the pillows. "No! Cheesecake, you can't leave me now!"

"Nice," he commented. "Did you ruin it?"

"Yes," they groaned, playfully pouting as they dropped the poor remains onto the plate and shoved it aside. "Now, I'm going to have to wash the blankets. Goddamnit."

"Smooth. Here," he said, scooping the last bit of cake onto his fork and then offering it to them.

They bit back a giggle. "For me?"

"Take it before I change my mind."

Quickly, they leaned over and took the bite. "Okay," they said, flopping back onto their back. "That was perhaps the most romantic part of this yet."

He paused and then shook his head. "If I'd known the bar was that low from the beginning, I would have been spoon feeding you hours ago."

Frisk snorted. "I'll, uh, be real with you and tell you that honeymoon's are mostly an excuse for a vacation and to fuck. So, honestly, if we just took the day off to bone in bed, that'd've worked too."

Sans shook his head again. He'd been right; Frisk had been pulling a prank on him. "God. Damn it."

Laughing, Frisk patted his shoulder before looking back up at the rotating stars. "Hey."

Sighing with every bit of frustration he could fake, he answered them. "Hey."

They turned their head to smile at him. "This was actually a really nice day. Thanks."

He looked at them sidelong and for a rare moment, all trace of sarcasm and mischief disappeared, leaving him looking surprisingly sincere. "I'm glad."

Rather than ruin the moment with a joke, Frisk chose to just smile back before turning to look back up at the stars, Sans following suit a second later. Soon enough, they'd both drift off, feeling warm and safe and comfortable, leaving behind a very silly sight of two adults' legs sticking out of a lopsided blanket fort. But for the moment, it was best honeymoon either would have wanted.

A/N: This chapter was a bitch that didn't want to be written and it took everything I had to get it out at all. I'm sad I didn't get it out in time for the actual middle of November, but oh well. So, yeah, anyways, life's still rough, but we're trucking along still. I will say we're getting close to the end of the 'canonical' part of the story, which is supposed to lead into the true sequel of TW, UD. So, in case you're curious, No, I'm not giving up on the story-we're like four or five chapters from the end (of the canonical parts and then there's not a ton of requests for me to even do for the noncanonical stuff). I'll see this thing through, okay.

This chapter was a request from couple people, including kawaiiloverq and venelona. Hope it didn't disappoint (too badly).
