Fell! Sans POV
Well great. Boss kicked me out again because I didn't went for patrolling and was lazy to get up. Stupid asshole.

And here I am, in Grillby's, drinking mustard as the usual. Suddenly, someone touched me. I looked behind to see my friends. "Hey Sans, do you know there is a fight going out here? And a girl is challenging Skullsoul (My Underfell OC). Wanna check it out?"

He told as I thought and said : "Fuck yeah. Bring me to the fight." I got up from the chair and told Grillby I would pay the tab next time.

I opened the door as I saw Skullsoul being pushed behind. "Damn, (Y/N). How the hell you are this savage, girl?!" She said and got up, holding her scythe and wounded.

"Cause I am naturally one badass, Soul! I learned how to fight on the surface!" I heard another voice I never heard before. I ran to the crowd as I saw Undyne helping Skullsoul up as the girl with (F/C) hair came up to them.

"Good fight, ya bitch."  "Yeah thanks. Next time I am challenging Papyrus. He seems easy to you but I want to try on him." "Sure. I will tell him about it anyway. You know his brother got kicked out this afternoon?"

Tch. Fuckin Skullsoul. This bitch, same as Boss. "Really? Sounds like your annoyingly, positively, childish brat of your so-called brother."

Skullsoul groaned like Boss does and summoned bones in a sudden and aiming at me as I fell into a snow puddle. I cursed as I got up from it and tched.

"Really, Skull?! Why the fuck do you have to shoot your fuckin attacks at me, huh, you bitch?!" I shouted at her and pointed my middle finger as my eye glows.

"Oh shut the hell up, you lazy ass! Don't say that shit to me, say that in Boss' face then!" "Damnnn. You curse so much more than me, dudette. That's Sans?"

"Yeah, Boss' brother."  Bones came from ground as I avoided them. "Oh, so you do wanna disclipine me, don't you, Skullsoul?!" "Yeah, that's what Boss does to you, don't you?!"

We kept arguing by fighting each other as the girl who was in the corner, eating chocolate and having a chat with the mutts, Dogamy and Dogaressa.

"Got ya, you little shit."  I heard her saying as I got my ass hit from her Gaster Blaster and got oofed on the fuckin snow. I lifted my face up and surrendered to her.

"Fine, ya win you little fucker. Next time, it won't be easy." "Oh really, you got a BONE to pick with me? Try me, bitch."

"Oh~ The Sans the Skeleton is already mad~?" I stopped as I turned around to see the girl earlier on. I suddenly blushed.

"W-well.. No!" She chuckled and put on a hand for me. I grabbed it and shaked it. "I'm (Y/N) (L/N), a fallen human fell 10 months ago. KNIFE to MEAT ya, Sans the lazy ass skeleton."

Damn. She's savage. And hot. And sexy too. Wait... What the hell am I thinking?! And so many puns huh? "Eh~ (Y/N), I think someone's got a crush~" "Well shoot, who, dudette?" "The one and only you, (Y/N). Who else?" Skullsoul spoke the truth as I clenched my fists hard and put up my hoodie.

"AH FUCK YOU, SKULLSOUL!" "FUCK YOURSELF, SANS! OR FUCK MY BESTIE AS WELL!"  This little bitch! If I got her, I'm going to beat her BITCHY ass.

(Y/N) POV
I'm a bit flustered. This lazybones has a crush on me and that went from zero to a hundred like lighting fast. Seriously, though. He likes me that fast?

Holy crap. Let me get my ass back home to figure and calculate what the hell just happened.

I picked up my weapons and bottle, Skullsoul comes over to talk with me. "Dudette, did you know that Sans likes you ever since I helped you out from your living hell?" She told me and made me surprised.

I didn't expect a monster like Sans to like me. A badass? Seriously. I sighed as I smiled at her. "Yeah. I know that he likes me. So do I. But I'll keep that aside for now. Can I come over to your house?"

"Sure, Dudette. Always welcomed for you anytime." "Thanks, Soul." "Anytime, (Y/N)."

She then called Frisk, another human like me who has DETERMINATION in her, jumped off the huge rock and landed on the snow ground. She ran towards us as we begin walking and saying our byes to Dogaressa and Dogamy and the rest of the monsters who enjoyed the fighting scene.

Sorry if this is short. I ran out of ideas.
