Frisk's P.O.V.
The smell of cooked spaghetti filled the entire house. Guess Papyrus started cooking dinner already. Sans say on the couch and turned on the TV.
I soon found myself surrounded in a blue aura and off the ground. I giggled while Sans set me on his lap.
We then kissed. It felt amazing as always! Papyrus walked into the room.
"AH, BROTHER!" Papyrus said in his loud, sweet voice. "I SEE--ER--FRISK IS HERE. HAVE YOU FIGURED OUT THE ROOM PROBLEM YET?"
I cocked my head at Sans. "'Room problem?' What's that supposed to mean?"
"Well, we don't have any extra rooms." Sans told me, with disappointment in his words.
I gasped and smiled. "We could just build another fort out of unused blankets, pillows, and other things!"
"AH! GREAT IDEA HUMAN!" Papyrus said while patting my head. We immediately got to work.
~time skip~
My room looked AMAZING! Even though it was made out of old blankets and strung up to the wall in the corner of the room, it still had potential. It was big enough for me to sleep well...and have privacy.
"AGH! It looks so good you guys!" I hugged Sans and Papyrus. "Thanks so much!!"
"Heh. No problem kid," Sans told me, pressing his teeth on my forehead. "We want you to feel at home anyways."
I smelt the air...it smelled like burnt noodles and spices. "UM! I NEED TO TEND TO THE KITCHEN!! NYEEEEEEEH!!" Papyrus yelled, running back to his spaghetti. I just giggled at him and went into my new room. I'm gonna love this new home!
~time skip: Sans, Frisk, and Papyrus had their dinner.~
Sans' P.O.V.
Frisk and I were sitting on the couch, watching TV. I needed to take a breather, after eating slightly burnt spaghetti.
"Hey, kid," I told Frisk, smirking. "I'm gonna head outside for a bit, okay?"
"Awww!" Frisk said, a little disappointed--but I knew she was just kidding. "Fine! I'll see you in a bit I guess."
I have her a little peck on her lips and opened the door.
I headed to the back of the house. I leaned against the house, closing my eyes. I smirked again, knowing that Frisk is mine...and I'm her's.
"Heya, Sansy~" a familiar voice greeted me. I opened my eyes to find a green-flamed, "cosplaying" as a school girl, rude and disrespectful, Fukufire.
"What do ya want?" I said, coldly. My eye sparked a little blue flame. I don't like her one bit...especially after she made fun of Papyrus.
"Oh! Feisty today, aren't we?" Fukufire told me, her hand reaching my cheek. I slapped her hand away.
"Get away?" I said, backing away.
"Aww! But Sansy~" Fuku said, pouting. "You know we both have feelings for each other, so why hide it?"
"FEELINGS??!" I said, my eye glowing brighter. "You think I have 'feelings' for a rude monster like you?" (A/N: WOAH CHILL SANS!)
"Hehehehe~~!" Fuku laughed. I just looked at her, a frown formed on my face. "I can MAKE you like me!"
And with that, she grabbed my hoodie and she pressed her face against mine. I tried pulling away, but her grip was tight. I blushed madly, mumbling under my breath trying to tell her to stop.

Frisk's P.O.V.
What's taking so long?
I opened the door and walked outside. Sans wasn't on the porch...so I walked behind the the house and saw Sans' hoodie. I smiled.
(A/N: play vid at top if you wanna!! :3)
"Hey! What's taking so---" I tried asking, but I stopped. My smile faded away. My legs wouldn't move. There I saw, Sans and some random girl, kissing. KISSING!!
"MMMMPH!!" I heard Sans scream under his kiss. Tears formed in my eyes. Sans then was done with his "make out session" and turned to me.
"S-Sans...you..." I tried getting out. Tears was now visible to every monster in the UNDERGROUND. Sans ran up to me.
"I-it's DEFINITELY NOT what it looks like!!" Sans said, stroking my cheek with his hand. I slapped his hand away, crying as I did it.
"Y-YOU IDIOT!!" I yelled. "WHAT THE FUCK WERE YOU THINKING?!"
"F-Frisk...I--" Sans reached out to grab me. I back away, interrupting him as I did.
"NO!" I kept yelling. "NO!! WHY WOULD YOU CHEAT ON ME?! D-DAMMIT SANS!!"
I ran away. I kept crying. DAMMIT SANS!! I didn't think that HE would cheat on me. I could hear Sans calling my name behind me...but I kept running.
I thought I was finally in a good place. I thought I was finally happy. ...I thought I could trust Sans.
