Under the mean face(Underfell Sans x reader)[COMPLETED]

The soul fragment

(this is the second mask I've been doing, it's a bit deformed and the back looks like shit, but for a first time, I'm happy about it. Anyway, let's get back to the story.)

Did I just cracked the wall... daaaaamn that was a strong punch! I looked at my knuckles, they were a bit red, but no injuries or anything. Okaaaay..... I stared at my fist then back at the wall. I tried to punch the wall again, but.....

You- SHIT!! OW! WHY DID YOU BETRAY ME, FIST!? I TRUSTED YOU!!

I held my hand in pain, biting my lip to blood. Shit! That hurts! I hissed in pain and cursed loudly. I looked around the room, searching for the ice pack I used on my cheek. I putted it on my knuckles, swearing again. I heard some footsteps that became louder and louder. They were running. Huh, probably Sans, aaand as I expected it, the skeleton bursted in and looked at me.

Sans- WHAT THE FUCK HAPPENED!!??

You- Jeez, why you screaming? I should be the one doing that.

Sans- You screamed, how was I supposed to react?!

You- You should've done nothing, I'm okay, I just tried something stupid.

Sans- No, you didn't... tried to remove the fragment?

You- No no no! I just just punched the wall, but the second time was painful. Look, there is the mark of the first one.

He looked where I was showing, he at first was kinda confused, but then his eyes grew wide.

Sans- Ya did this crack?!

You- Yup.

Sans- How?!

You- I.... don't know. All I know is that the second time didn't worked well.

Sans- Yeah, I can see that. Well, I'll try not ta make ya angry. I wouldn't want your fist in my skull.

You- Yep, you better......

The room went silent. A heavy feeling of ankwardness engulfed the room, tensing up the air. We were just staring at eachother, almost making a stare contest.

You- Ok, I'm sick of this, it's too silent. I'm tired of you protecting me and all but hiding all the important things from me. So I'm gonna do as I want either you like it or not. You're doing things on your own so I'm gonna do it too.

Sans- But (y/n)-

You- No but, I'm doing it, so here are your choices, you help me so I don't die or you let me do it alone because you're too stubborn. Choose right here and NOW.

Sans- But it's too dange-

You- I. said. Choose.

Sans- *sigh* Fiiiine, I hate you.

You- I know you don't.

I smiled playfully at him and hit him childishly in the shoulder. He chuckled a but then got back his serious face.

Sans- Then, I'll need some stuff.

~time skip~

Finally, the setup was finished! Glass cylinders full of weird liquid were placed near an operation table. A lot of wires were connected between them and the table. Sans was gonna remove the fragment of my soul and put it into the cylinder. It was gonna be painful, but it was for a good cause. I sighed deeply then went on the operation table and layed down. Sans wrapped the belts around my wrists and ankles so I wouldn't struggle to much during the process. My breathing quickened, but I shut my eyes and focused on the good things.
