A/n: I'm gonna be cliche and put in Drop Pop Candy

Sans' POV

I'm only doing this for Star. And I swear if Alphys planned shit for her and me, I'm gonna...

Eh. I'd thank her. I am bad with relationships, and one with her is an example.. so it's a really big help if she were to do that for me of all monsters.

~•Timeskip to getting to the party•~

"Good that y-you guys c-could c-come." "Thanks for the invite too, Alph." Y/n said. "No p-problem, haven't hosted a p-party in like forever. Come in, Undyne just set up the Kareoke m-machine! A-and I invited Catty and Bratty too, they were p-passing by and we w-were friends since we were kids." We walk inside, the Kareoke machine on a small stage, a giant couch, and some tables—giant couch?

Your POV

Sans walks over to the couch and sits down, really chilled out. Like he just found the perfect seat for his non-existent ass.

A blue fish humanoid with red flowing hair stands beside the machine. When it catches sight of me, it looks at Sans then to Alphys and sighs deeply, retaining a toothy grin. It walks over.

"So, you're the other human's sister?" "Yup." "And you're human too?" "Yup."

She glares at Sans, and he shoots one back..? "Well I'm Undyne, Alphys' girlfriend. Nice to meet you... uh.." "Y/n. Nice to meet you too." Alphys' girlfriend? Aww, that's sweet. She seems pretty nice, apart from the fact that Sans and her are holding a staring contest I don't know about. And it's pretty intense.

"O-Okay guys, so I called you all h-here not just for K-Kareoke and a party, but like a contest. Other games too, b-b-but I'm not spoiling anything y-yet! The game mechanics are.. uh.. Undyne?"

"Oh, right. Contest is by teams of two each, in order to win there will be two judges—Alphys and I—that would—" "Who said anything about only two judges?~" A box shaped robot blasted through a wall, sending pieces of fake wall through the air.

"M-Mettaton?" "Uh, what?" Sans stood up from his comfy seat on the couch.

"Yes, darling! I'm gonna be a judge for your little competition to make things more exciting!" "How is that gonna make things exciting?" Sans mutters, chuckling.

"O-Okay then. Undyne, you m-may continue." "Uh, one judge instead so we can join... that would give you a score on a scale of one to ten. The highest pointers win. And team picking is done by the judge.. so.. MTT?" "Hmm.. Frisk and Papyrus, you two are teamed." Mettaton examined(?) Sans and then me. "You two, teamed." Ok, I've done that before with him. This should be easy! Only my friends are watching, no cameras.. yeah!

"Catty, Bratty, you two are teamed and.. Alphys and Undyne. Draw straws or whatever fits you to see who's first."

"Alright then, punks. The twist is a random song is gonna play and you gotta sing it or lose! So good luck and.. Alph and I are gonna win!" "NYEH HEH HEH! DON'T GET TOO COCKY, UNDYNE! FRISK AND I SHALL WIN, AND YOU KNOW IT!" "Bratty, we gotta win this! Like OMG, Mettaton's judging!!!" I look at Sans and he's sweating for some reason.

"Sans, you okay?" "Y-Yeah, I'm fine. Uh, who's going first again?" "I dunno, didn't pick yet." "Sis, we're about to start!" She tugged my sleeve. "What?! When did you pick who goes first yet?" "Oh, don't worry. You two are last!" "Oh.. uh ok.." I sit down on the couch next to Sans.

"Something's a bit wrong about us being last... don't you think?" "Yeeeahhh. I bet they're gonna make us sing a really cheesy song and put it on video." "Haha, and then they're gonna use it as blackmail some day." "Or they'd post it online and then a whole fanclub will be dedicated to shipping us." "They're all gonna be like 'OMG SANY/N FOR LIFE IF THEY KISS IM GONNA DIEE'" I make my voice high pitched. "And Alphys is gonna be the fanclub's president." Sans chuckles.

'Catty and Bratty' I think are up at the stage. "Hello, everyone! We're like, gonna win this so prepare yourselves! ... Bratty, Bratty!!" The cat girl whispered something to the alligator, pointing at Sans...? The girls giggled as the machine picked a random song. They picked up their mics and the lyrics appeared on the screen.

The music started. Catty started singing, it was exaggerated, but on key surprisingly and she made poses to Sans for whatever fucking reason she had. Then the alligator, probably Bratty started singing Meghan's part staying where she was, whilst Catty came closer to Sans, swinging her large hips, tail swaying.

"Uuuuuhh.." Sans sweats, is that blush? Pfft, couldn't be. Then the cat girl sits on his lap, facing him. Sans looks at me, flustered. What the actual fuck? Am I jealous? Damn, I do love Sans. I don't get jealous for shit, this is serious.

"Wanna have a great time, baby?" She stroked his chin with a finger. "N-No.. Uh.. P-Please get off me. I don't really want to..." He pulls the collar of his shirt.

"Awww, so you're with this garbage already? I could do way better, you know..." She purred, glaring at me. I feel my fists get ready to land on a furry little face. Sans uses his telekinesis and lifts the probably 200 pound cat off, and places her back on the stage with her friend. He sighs of relief. I sigh of relief.

They end the song, earning a small applause. Not from us, no. Mettaton scribbles something on a paper.

"Yeesh." He rests his head on a hand. "What was that all about?" Sans shrugs. "Why, you jealous?" Sans grins, but blushes. "Maaaybe.." I lied. I am. Well, was. "Wait, what?" He blushes more. I laugh, running a hand through my hair.

"Next up, Frisk and Papyrus. Good luck, darlings!" Mettaton exclaimed. The two get on the stage, the machine flipping through songs until lyrics pop up. They grab the mics and get ready to sing.

[A gif or video was added here in a newer version of Wattpad. Update now to see.]

A/n: Frisk is singing Sans' part. And.. PSYCHE! You two aren't gonna sing it, nope!

Frisk and Papyrus' singing is very upbeat like the song. They're both on key and the voices together fit like gloves. Who knew Papyrus was a good singer?

"They sing really good." "Yeah but I think this is one of the timelines where Paps took some lessons..? Eh. Too lazy to ask." "Pshh. I'm sure it just runs in your family." "Maybe.."

The song ends, everyone applauds. Mettaton scribbles again on the same paper.. maybe scores?

"Alphys, Undyne, your turn~" Sans grunts. "He doesn't need to say it, they already know.." "Hey, just a thought.. why don't you like Mettaton?" "Well one, he's loud and annoying. Two, Papyrus likes Mettaton. Three, Papyrus likes Mettaton." "Oh.. Well he doesn't seem that bad.." "He tries to kill Frisk multiple times every timeline because of his stupid game shows." ... "Okay, that's reasonable."

Alphys and Undyne get on stage, grabbing the mics. The machine picks a song, lyrics appearing on the screen.

[A gif or video was added here in a newer version of Wattpad. Update now to see.]

Oh my God 'Sad Machine', Alphys, your Kareoke machine is amazing.

Alphys doesn't stutter, but she's blushing as her and Undyne hold hands while singing. They sound amazing together. Maybe this 'timeline', as Sans would say, is when everyone can infact sing.

I applaud with Sans and the others, some compliments here and there as they walk down the stage. Mettaton scribbles something down on the paper again.

"And last, but not the least, Y/n and Sans!" How does he know my name though? Maybe he heard someone mention it?

We walk up to the stage, grabbing the mics. The screen flips through various songs, and it stops flipping on a title. 'Say You Won't Let Go'.. This should be easy, it's our ringtones for Pete's sake.

The guitar accompaniment starts, lyrics appearing on the screen.

A/n: If you really don't know the song, RIP

"I met you in the dark, you lit me up." Sans started. "You made me feel as though.. I was enough." "We danced the night away, we drank too much.." "I held your hair back when you were throwing up." He looked into my eyes.

"Then you smiled over your shoulder, for a minute I was stone cold sober. I pulled you closer to my chest.." "And you asked me to stay over, I said I already told ya. I think that you should get some rest."

"I knew I loved you then, but you'd never know. 'Cause I played it cool when I was scared of letting go. I knew I needed you, but I never showed, and I wanna stay with you until we're grey and old." I continued. "Just say you won't let go.. Just say you won't let go." Our voices synced. I blush, thinking about the lyrics.

"I'll wake you up with some breakfast in bed, I'll bring you coffee with a kiss on your head. I'll take the kids to school, wave them goodbye, then I'll thank my lucky stars for that night." I sang.

"When you looked over your shoulder, for a minute I forget that I'm older. I wanna dance with you right now.. Woah Oh.. And you look as beautiful as ever, and I swear that everyday you get better! You make me feel this way somehow.." A dark blue light glows from the inside of his ribcage.

"I'm so in love with you, and I hope you know.. Darling your love is more than worth it's weight in gold." We sing together. "We've come so far my dear, look how we've grown. And I wanna stay with you until we're grey and o-o-o-old~" He sings, then I continue it.

"Just say you won't let go, Just say you won't let go..."

For some reason, the machine stops working. But the mics are still going, so we continue the song.

"I wanna live with you, even when we're ghosts. 'Cause you were always there for me when I needed you most." I sing, still on key.

"I'm gonna love you 'till my lungs give out, I promise 'till death we part like in our vows. So I wrote this song for you, now everybody knows.. That it's just you and me until we're grey and old." His heart—and soul—is in the song.

"Just say you won't let go.. Just say you won't let go.. Just say you wo~on't let go, oh just say you won't let go." Sans is a royal blue, as I might be tomato red.

Everyone applauds, it's louder than the others. "Well it's no doubt who wins. Congratulations, you two are the winners!" Confetti is blasted from Mettaton's party canons. Wait, party canons?

Cheers and applauds fill the room. "What do we win though?" Sans says. Good point.. "Games! For the night has just begun!" Okaay..

~•Timeskip to after the party•~

"NEVER agree to games with Mettaton.." I plop down on the olive green couch with Sans, both of us blushing. A lot.

"The Pocky game, I tell you.. yeesh...." He rubs the crook of his neck. "Heheheheh! Never know when he's gonna pull a trick like that!" Frisk giggles.

"Well it's like midnight, better hit the hay." "Yup. Oh, shouldn't we be at the Inn?" Frisk says. I forgot about that place.. heh. "NONSENSE, HUMAN! IT'S TOO LATE FOR YOU TWO TO GO OUT THERE, ESPECIALLY WHEN IT'S FAR!" "Thanks for letting us stay for the past few days, by the way. Hope we're not much of a burden.." "It's fine, not like it's a bother anyway. I'm going up, bone-tired right now." Papyrus grunts, going upstairs. "COME ON, HUMAN FRISK! LET'S HAVE A SLEEPOVER IN MY ROOM!" Frisk giggles, following Papyrus. I get up, Sans teleports.

I get to the stairs, when a thought hits me. Why should I sleep in his room? He only really allows me either because he brings me there himself or if he wants me to. I get on the couch.

Sans teleports beside me. "You coming or not?" "Wait, really?" "You've been sleeping there with me for the past few days, duh." He ruffles my hair, chuckling. "Oh, ok." I stand up, fixing my hair again. He teleports, but this time with me.

I get on the mattress, he gets in beside me and I close my eyes.

...

"Hey, Star uh, you awake?" He shakes me gently. "No." I groan. He pokes at my neck, my ticklish spot. "S-Sans, nuh!" I sit up, swatting away his hand.

"What?" "Well, I was thinking about the party, and you said maybe you were jealous. Were you or..?" "Uh.. yes. She looked like she was about to rape you, anyway." I run a hand through my hair. He chuckles softly.

"Oh.. so... does that mean you uh.. like me?" He blushes. I guess I should tell him now. "I like-like you, actually.." I feel the heat in my face get stronger, and I think my soul is beating faster.

"O-Oh. Wow, uh.. I dunno what to say.."

"How about I start with 'I love you', Star?" He grins genuinely. "I love you too, Bones." I kiss him on the cheekbone. "Goodnight, Sans.." I silently sigh of relief, fist pumping. He pulls me into a back hug, dragging me down into the mattress. "Goodnight, Y/n." He kisses my cheek.

I sleep soundly, head rested on his ribcage and his arms wrapped around me.
