The next day you, sans, and papyrus begin to set up for the party. Undyne was busy picking out the biggest Christmas tree she could find. You told her to pick one that would fit in the house this time. Things were going great. All the invitations were sent out thanks to pap, and the decorations were hung all around the room. Sans, as expected, was sitting on the couch taking a small nap.

'Not for long'  You thought to yourself.

You grab a Santa hat and set it on top of his skull. You then grab some Christmas lights and wrap them around him. After plugging in the lights you sit and stare at sans looking like a Christmas tree himself. Surprisingly he still didn't wake up. You needed help putting up the lights outside but figured you could just get a ladder out of the shed. You left sans in his red and green cocoon and continued to decorate.
After grabbing the ladder and setting it up against the house, you go and grab the rest of the lights. They were heavier than they looked. You put them over your shoulder and begin to climb. The cold, dry air brushed against your face. Once at the top you set the lights in place one after another. Suddenly a strong gust of wind throws you off the ladder. You scream out of fear and brace yourself. You slowly open your eyes to see you were flouting just inches from the ground. A faint blue glow surrounding you. You look up to see sans with his arm extended towards you. He was out of breath and beads of sweat dropped from his skull.

" Can't take my eyes off you for one second can I?" Sans says as he lays you on the ground slowly.

" sorry sans. I thought you were asleep." You say.

" Not after that scream I'm not." He said as he sits on the ground, completely exhausted.

Sans stands up and tried to help you to your feet. You go to stand up only to fall back down. Your legs were numb from the shock. You smile awkwardly at sans.

"I guess you could say I'm falling for you sans." You say trying to make him laugh.

"Heh didn't know I could  make ya weak in the knees." He says laughing.

He pulls you up again and wraps his arm around your waist keeping you close. You look into his eyes and smile. You were only inches away from each other. He leans closer to you and your face heats up.

"FRISK WHERE SHOULD I PUT THIS MISTLETO....WHAT ARE YOU TWO DOING?" papyrus says through the window.

You and sans become flustered and quickly separate. You didn't know what to say to papyrus and to make things worse you were beat red and unable to look him in the eyes.

"The kid had something in her eye and I was trying to see what it was." Sans replies in a somewhat calm way.

"OH, OK. ANYWAY WHERE SHOULD I HANG THIS?" papyrus asks again.

"P-put it on the top of the kitchen walkthrough." You say still unable to face him.

You and sans look at each other and laugh. You both walk back into the house and continue to decorate. In the end it was papyrus who hung up the lights outside. Everything was ready, all you had to do was get dressed and wait for guests. Then it occurred to you, you have no idea who is coming. You run to pap and ask him who all he invited.

"WHO DID I INVITE? WHY EVERYONE OF COURSE." he said.

"by everyone you mean..?" You ask now scared of the reply

"Alphys, Mettaton, Torial, Asgore.." You cut him off.

"Asgore.. You mean the person who wants to kill me Asgore?" You say with fear in your eyes.

Papyrus goes to say something then realizes what you mean and stops. You quickly run up stairs to sans room. You find sans sitting on the bed putting on his jacket. You rush to him and put your hands on this shoulders. You quickly explain the situation. He thinks over the situation and tries to come up with a solution.

" Guess we forgot about you being human huh." he says scratching  the back of his skull pondering what to do.

"What am I gonna do, he will be here in an hour." you say, pacing around the room.

"Chill we'll think of something" He says reassuring you.

You think for a few more minutes and then it hits you.

"What about a disguise!" you offer waiting for his opinion.

"That's perfect, but what would we disguise you as?" he says.

You run to the attic with sans and see if you have any costumes that could work. There were a couple old wigs that you saw, but none would help changing you from human to monster. Sans picks up an old tux and bow tie and hides it from your sight. You saw what he was hiding and giggled to yourself. You didn't know sans would ever wear a tux. You continue to look around moving things all around the room. Then something catches your eye.

"Hey sans, would this work?" You say holding up a pair of pixie wings. "Wait why do you have this?" You ask.

He shrugs. " I don't know why we have that, but it won't work it's not very realistic" he says pointing to some fray on the end.

"I guess I'll keep looking then." You jump to the back to some boxes labeled 'costumes'. You thought to yourself, 'That is way to ironic to be true'.  You signal sans over and open the box. You find bits and pieces of anime costumes all over the place. You look at sans with a blank look as if to say 'Why'. He laughs pretty hard at your confusion.

"Look kid, these are from Alphys' anime stuff that she gave to pap. Don't go judging me for this." He says in defense.

You didn't mind the fact they were all anime creature costumes. You were just surprised to think that Sans would have them. You look around in the box for awhile trying to pick something that would look real. Sans hands you a nail kit that seem to look like claws. You kept it beside you as you continued to look. There were some dragon tails and multicolored wigs. You even saw a maid costume from a show called mew mew kissy cutie.

~(Trying to reference 'Tokyo mew mew' it was the only thing I could find with a close title.)~

You rummage through the boxes for awhile. You found at the bottom of one of the boxes, ears and a tail of an anime fox. You put on the ears and noticed it matched your hair color. You put the tail on and turn around to show sans. He shows an absent minded look.

"Wow I cant tell those are fake." He says with his hand on his skull.

"Really!? Great so I can be a fox girl." You say excited that you found something.

"Yeah that sounds good, just try not to get caught." He say patting your head.

"I wont" You say as you run down stairs to show papyrus.

Luckily there were no guest yet. Undyne walks in with the tree and sets it up. They look at you confused by your get-up and you explain the plan. They agreed to try and cover for you as much as possible.

    You went upstairs to fix your costume a bit and put on the dress you bought the other day with sans. You apply the fake nails/claws and fix your hair around the ears. You look in the mirror to make sure everything was correct. You hear a whistle from behind you. You turn to see sans in the doorway.

"Hey kid you look amazing. I guess you could say the disguise is purr-fect." He laughs.

                                           ~(I know not a cat just work with me here.)~

"haha thanks sans, for everything." You say sheepishly.

"Heh no problem kid, I like helping ya out." He says patting you on the head again.

As he walks away you feel a faint blush run along your cheeks. This got you thinking, what were you to sans. How did he see you. He always called you kid, but you kinda liked that. You wonder what your relationship was to sans.

~~~~~

Finally some guests arrive. The first to arrive were Alphys and Mettaton. Papyrus introduced you to everyone that walked in. You happily greeted everyone and made small talk. After a bit almost everyone had arrived. Asgore was the last to show. It was nerve wreaking thinking about meeting him. When you hear a knock at the door you heart dropped. This was it, the moment of truth. You open the door to see a large goat-like man with a large beard. He gives you a big smile and extends his hand to you.

"Nice to meet you." He says with a big smile.

You hesitantly shake his hand and welcome him inside.

"N-nice to meet you too. I-I'm Frisk, sans' and papyrus' roommate.

He walks in and begins to greet the other guests. He seemed really friendly. You felt bad lying to everyone, but this was the only way you could stay here with the skelebros.

   You walk around and have some laughs with the other guests. You got to know a lot of them and became friends rather quickly. Alphys and undyne were sitting on the couch talking. They seemed to have a good relationship by the looks of it. You saw Mettaton, papyrus, and napstablook hanging around the Christmas tree chatting. Apparently Mettaton and napstablook were cousins. You walk around and find Torial and muffet in the kitchen admiring the food you and papyrus cooked. Sans was nowhere to be found. You tried looking for him and saw a small.... Dog? Cat? shaking in the corner. You walk over and see the small monster.

"Hoi! I'm Temmie." It says.

"Hi Temmie, are you having fun?" You ask.

" Do you's have Temmie flakes?" It asks

"Um I think papyrus put some on the food table." You say pointing to the table.

"Tank you." It starts to walk over to the food table still shaking intensively.

'okay?' You say to yourself.

You went to look for sans again. You wonder if he went back to his room. You try slip past everyone to go upstairs, but you are stopped by Alphys.

"E-excuse me, but I c-couldn't help but notice your ears and tail. T-they look exactly like the ones from an anime I'm watching." She says sheepishly.

"O-oh uh really? That's a funny coincidence huh." You say nervously.

 'Omg she knows I'm in costume what do I do?'  You quickly think of what to do but your mind is drawing a blank. You suddenly feel a hand on your shoulder. You look up relieved to see sans.

"Don't worry kid I got this." Sans whispers to you.

"Hey Alphys, do you remember that thing I told you earlier.

"Oh, y-you mean t-this is the.... oh I'm so sorry." She says looking at you.

"Its okay." You say confused about what sans had told her.

Alphys leaves and rejoins undyne in a conversation. You look at sans and let out a breath you didn't know you were holding.

"What's wrong kid, you look like you've seen a ghost." He chuckles.

"I have and he loves music. " You laugh. "looks like you've saved me again."

"Hey, by the way, where have you been I was looking everywhere for you." sans says with his hands in his pockets.

"Me? I've been looking for you." You say.

You look at each other for a minute and laugh. Who knew you were both just running around in circles. You walk outside to get some fresh air. You and sans sit outside behind the shed and relax a bit.

Sans takes his hand out of his pocket and holds up a mistletoe above his head. Your face instantly turns a bright pink.

"W-where did you get that?!" You say.

"Doesn't matter." sans says with his evil grin.

"The real question is, will you kiss a skeleton?" he says.

Your pink face turns into a bright red as he says this. 'he doesn't even have lips' you think trying to get past your embarrassment. Sans turns his head to the side and leans closer to you. He puts his finger to his cheekbone and says:

"I'm waiting." he urges you.

'Well its now or never' you thought to yourself. You grab his face and turn it towards you. You quickly press your lips against his mouth. You finally let go and look back at sans. You see his face light up a soft blue color. He looked very flustered. Your face shows no sign of calming down. He puts his hand to his mouth trying to hide his own embarrassment. You smile.

"The answer is yes. I would kiss a skeleton." You smile.

"What am I gonna do with you kid." He says still hiding his face.

You take his hands away from his face and laugh.

"Aw sans no need to get blue in the face" You snicker.

"Ah shut up." He says pulling you into a hug.

You hug him back and smile.

"Merry Christmas." You whisper.

"Merry Christmas kid." He says still holding you close.
