A/N~ don't play the song now, there are going to be lyrics below.

Frisk's pov.

,,Just go and wake her up!"
,,no, you do it! do you not remember what happened last time, when she saw me first?!"
,,I do, but then you painted her face!"
,,well you helped me too, you know!"
,,Just don't be a little mouse and go wake her up!"
,,not happening!"
,,THEN I SHALL WAKE THE HUMAN UP!!!"
,,Papyrus shh, you probably waked her up!"
,,If she isn't up from you two shouting. I'll go and see her."-I heard a knock on the door. Mettaton walked in. ,,Good morning Frisk! How was your sleep?"
,,It was great actually! Well, they waked me up, but that's alright!"
,,Um, how much have you heard?"-he asked.
,,Well I heard that Sans didn't wanted to wake me up, because he tough that I will attack him and that Undyne said that he is a mouse."-I chuckled.
,,Well, okay then. You mostly heard everything. Now go, dress up, I will do your makeup and stile your hair."-I did as I was told. He putted just a little bit of makeup and putted my hair in a cute ponytail. We went downstairs where it seems like Undyne and Sans has stopped fighting.
,,Hello everyone! How was my not shouting when you slept?"-I said.
,,Sorry punk that we woke you up"-Undyne apologized.
,,It's okay. You all were awake already, so it's not a problem."-I said. ,,Now what's for breakfast?"
,,PANCAKES!!"-shouted Papyrus from the kitchen. Not long after, he came with five plates of pancakes and caramel sirup. They were delicious! As we ate I decided to ask them why they were arguing.
,,So why did you argued in the first place?"
,,Well, we wanted to wake you up and I sent Sans to do it, but he refused, because he thought that you will try and attack him again"
,,Why should I? Did you do something again?"
,,no"
,,So why then you were scared, little mouse?"-I asked. He slightly blushed.
,,well, i guess i can tell you. i had another nightmare, but this time you or chara actually did what you wanted to do"-he said so only I could hear. ,,i was scared, that here i will see not you but chara"
,,I'm sorry Sans. I really don't want to kill you, I promise"-I said. We continued eating our breakfast. After that, we decided to go to the movies. This time we picked ,,Beauty and the Beast". It was surprising that none of us went to it. We bought our popcorn and drinks and went to our seats. Nobody was there apart from us. We could sit where we wanted. We decided to sit on the floor in front of all seats. We could even lay on the floor! The film was amazing! I actually almost cried in the end. After the movie we went back home. We got bored really quickly again.
,,hey frisk!"
,,What?"
,,you remember what you dared me yesterday?"
,,Oh yeah, did you wrote that song already?"
,,yup and i made music for it."
,,When did you had time for that?"
,,well after that nightmare, i decided to not go back to sleep and work on this instead."
,,Cool"-I looked in the lyrics. My face probably gave away what I thought.
,,it was in one of my nightmares"-he explained. It was creepy. This song was actually really good, but I can see why it was in one of his nightmares.
The music started.

A/N~you can play the song now.

Count me in unannounced, drag our friends on the tile
I just follow your trail
You can't just follow my smile
All of your sins are aligned with this mood of mine
Cutting me to the bone
Nothing left to leave behing

You outta reset right now, just like it never happened
I didn't come for a fight but I will fight till the end
And this one might be your battle, might not turn out okay
I know you think you can kill me, but you've already lost the

GAAAAAME

And I LOVE the way you "hurt" me
It's DETERMINATION oh oh oh oh oh oh yeah
oh oh oh oh oh oh yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
I LOVE the way
I LOVE the way you keep on dying

I'm gonna break you to pieces just like you were your bother

Gonna kill you again, just like you killed your own mother

You're a fool with no past, say goodbye to your future

Pay the free, do it kid, I'm talking no inflation

Too many stab wounds and not enough items.
Too much time in the hall, I feel my sins start to crawl

Too many freaks not enough blood in the Game

You know I'd give your LOVE a four letter name
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh
Eh eh eh eh eh

And I LOVE the way you "hurt" me
It's DETERMINATION oh oh oh oh oh oh yeah
Oh oh oh oh oh oh yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
I LOVE the way
I LOVE the way you keep on dying

You kill me again
Again and Again
But I come back knowing so much more
Learning all your tricks
I'll make you sick, cause the truth is Sans I'll make you QUIT

Try to stay Frisk, please just stay Frisk
You're still good good, admit to this
Don't fight anymore, it's such a snore
One more step, and I'll make it war

And I still LOVE the way I "hurt" you

It's DETERMINATION oh oh oh oh oh oh yeah
Oh oh oh oh oh oh yeah

I LOVE the way
I LOVE the way
I LOVE the way you keep on trying
I LOVE the way
I LOVE the way
I LOVE the way you keep on dying

Everyone was looking at me scared.
,,What happened?"
,,You looked like you were possessed by someone"-said Undyne.
,,Y-You were smiling c-creepily"-said Alphys.
,,You looked like you were about to stab Sans!"-said Mettaton.
,,frisk? what happened?"-asked Sans.
,,I was feeling like I wanted to kill everyone. I wanted to erase everyone. I wanted to destroy this world"-I said. Everyone was shocked, except for Sans. He looked like he saw the devil himself.
I have never seen him so scared. He was freaking out.
,,Sans? You okay?"-I was scared now too.
,,it's just like in my dreams. you wanted to erase this world too. it's like you were possessed..."
,,By Chara?"
,,yes"
,,Oh, god Sans i'm so sorry! I don't know what happened! I promise I won't kill you!-I started crying. Suddenly I was pulled into a hug.
,,it's okay. i'm sorry i made you feel this way"
,,Aaaand the ship has sailed!!"-Undyne started shouting. ,,I always knew that you two would be a perfect couple!"
,,Undyne!"-I was embarrassed. ,,Sorry Sans that I got you into this mess. It must be weird for you, because you love someone else!"
,,meh it's okay kiddo,
as long as undyne doesn't know who she is, she can say whatever she wants"
,,So that means I can say this? Frisk and Sans, sitting in the tree! K-I-S-S-I-N-G!!"
,,Undyne! I swear to god I'm going to kill you!!"-I started screaming. Everyone laughed at us.
,,Frisk. In our group, you are the only ones that doesn't have a soulmate! I mean I have Alphys and Mettaton is with Papyrus! So the only ones left are you and Sans!"-okay she made a point. I never actually thought about anyone else in a romantic way. It's weird, because I never had a crush on anyone, because I only started going to school this month.
,,But Sans already loves someone!"
,,And we don't know who it is. It could be you Frisk!"
Okay now Sans couldn't hold any longer and attacked her. Wow, Undyne couldn't dodge his attacks and he was pretty strong.
,,undyne, i swear another word and i will punch you in the face!"
,,Your ship name would be Frans..."
And Undyne now has a slap mark on her left cheek. I really wanted her cheeks to mach, but I didn't attack her. We joked around for a little more and then an idea came to my head.
,,Hey, I have an idea!"-I said.
,,To kiss Sans?"-Undyne's cheeks were matching now.
,,As I said, before Undyne got hit, I want to spend a night in a trampoline park!"
,,Is this possible?"-asked Mettaton.
,,Yes, I have seen other people do that. We just have to go there and hid somewhere until they'll close."-everyone agreed with me and we headed to the park. We jumped around for a little and then everyone found a safe spot to hide. We had our phones with us so we could tell each other when it is safe to come out. The park had to close in about a half hour. I hid with Mettaton, Sans hid with Papyrus and Undyne with Alphys. After the park closed we still had to wait for about an hour and a half. When nobody was there and all the lights were out we finally came out of our hiding spots. It was 23.00 p.m. we had twelve hours in this park and we were absolutely alone! We could do anything! First of all, I went to the snack bar and got some food, because I was really hungry. Then we started jumping around and doing flips. I really wanted to learn how to do a backflip. Sans decided to teach me. After two hours I was finally able to do it! It was probably the most fun thing to do. We started to play chase in there. It was fun because you could only jump around. Then we were running on this really long trampoline and then at the end jumped into a pit full of fluffy pillows. After that we decided to play some music, because it was really quiet in there. We danced for a bit and then Undyne wanted a rematch from me. We danced again and I won. I was so tired, so I grabbed a pillow from that pit and fell asleep on one of the trampolines.

Undyne's pov.

,,Oh look! Our little angel felt asleep! What do you say? Should we make her face pretty again?"-I suggested.
,,yeah. that's a good idea! but where are we going to find markers for it?"-asked Sans.
,,I always have some, just in case!"-Said Mettaton.
,,Sweat! Let's mess up her face again!"-we started to draw. We decided to make her look really pretty, so we gave her a makeover.
,,Oh, she is so pretty! I can't wait for her to wake up!"-I said. It was fun drawing on other peoples faces. Oh she's starting to wake up. ,,We better start hiding before she founds out what happened!"

Frisk's pov.

I woke up. Nobody was around. I touched my cheek and figured out why.
,,You better have hidden well, because when I'll find you, you will pay Sans!!!"-I was so angry. Oh boy, I wish that he is hiding somewhere far away from here. I went to the bathroom and washed my face.
,,boo"-I got scared.
,,Sans! Don't scare me like that!"
he started laughing. ,,What's so funny?"
,,that this time it was undyne's idea to draw on you and you still thought it was me"
,,Okay bonehead, where is she?"
,,near the snack bar"-we went there and found her crying from laughter. I slapped her really weakly and then we all started laughing. Everyone else joined us and we decided to eat. There were some pizzas left for us. We heated them and started eating. We had so much fun there. After we ate and sat for a little we found giant yoga balls. Oh, yes! We decided to grab one for each and run to each other. We went flying everywhere, but didn't got hurt, because we bounced back from the trampolines. Then we played dodgeball for a little. Sans was perfect at it. None of mines or Undyne's attacks could hit him. I was pretty good too, but still got hit a few times. Alphys was pretty good at it too. She always calculated where and when the ball is going to hit. Papyrus and Mettaton where terrible at it. They mostly got hit every time. Undyne was amazing at trowing them. Only Sans was able to dodge them. We were pretty tired so all of us went to sleep. We still had six more hours so we decided to set our alarms for three hours. This time I waited for everyone else to fell asleep and then I fell too.
When we woke up we were way more energetic than before. We went back to the snack bar and ate some more pizzas. We jumped around a little more and then it was finally time to go back to our hiding places. It was a really fun night. When the park opened and it was finally save to come out, we headed back to the skeletons house. We were still really tired, so we didn't even bother to change into our pajamas and we just felt asleep in the living room.

A/N~another chapter coming later! I hope you like it!
