The Demon Inside of Me (Grillby X Reader)

Serious Talk - C9

-Grillby's POV-
The texts from (y/n) were simple and to the point.
"Hey, sorry about this, but can you come to Gaster's lab?"
"Also, we need to talk once you're here. It's important."

The "We need to talk" was terrifying. Was this about the song? I know I can't really dance, but she didn't seem to mind.
Could she be trying to give the phone back?
Did she hate me?

I can never tell with females...

I arrive as soon as I could - 6 minutes - and rapped on the door to Gaster's lab.

(y/n) opened the door, smiling up at me. She had a beautiful smile...

"Grill, you're not gonna believe this!" Her eyes lit up like candles.
"What?" I asked.

"Grillby! Lovely to see you!" Gaster appeared behind her.

We shook hands, a formality that I would've liked to skip. "Yes. You called?"

Gaster beamed. Must've been something in the water... "I have finally done it. After years of work, they are complete."

I knew Gaster was lying. He gave up on the Serif Project years ago! "Impossible," I breathe.

"No! Come with me! They're alive, Grillby! Our work paid off!"

(y/n), Gaster and I all went into the lift. I noticed that Gaster removed the stereo. Shame.

(y/n) jumped out of the lift first. "Grill, you've got to meet them! 1 is super funny and 2 is a huge cinnamon roll!"

I must've looked confused, because she explained that he was indeed a skeleton, but was extremely adorable.

I have to admit, I was jealous. But we're just friends, right? I tried convincing myself, and I failed. Miserably.

"Grillby, look! Here they are!"

"(Y/N)! WELCOME BACK! WHO IS YOUR FRIEND? WHY ARE THEY MADE OF FIRE?"
"hey (y/n). who's that?"

(y/n) could barely hold back her excitement. "This is Grillby. He's my... uh," She looked at me, unsure of what to say.

I had no idea. I wanted to be more than friends, but wasn't sure she did too. I loved her, but didn't know if she felt the same way.
We ended looking at each other for a good 30 seconds before 1 said something.
"so you two are like that, huh?"

(y/n) turned red and I could feel my face getting hot. Well, hotter than normal.

"no problem, Grillby. i'm chill with that. besides, you've obviously got the HOTS for her, huh?"
"NYEH HEH HEH HEH HEH HEH! GOOD ONE, SANS!"

(y/n) smiled. "Sans?"

"i decided on the name when you were gone. 2 here is papyrus."

I smiled. "Those are great names."

Sans smiled even wider. "you think so? that's cool!"

"Cooler than him," (y/n) muttered, which made me chuckle.

Sans, Papyrus, and Gaster all walked off somewhere to get something to eat.

"Grillby? Do you remember when I first came here and you sent me a letter? Why did you want me to leave? What's the Serif Project?"

I knew I had to tell her.

"A few years after the monsters were banished to the Underground, Gaster asked me to be his lab assistant. Being the naive teenager that we were, we thought that we could create monsters with up to triple the power of humans."

"But?"

"We were foolish. There was no way that we could do it. I quit the project, saying that it was dumb and impossible without proper equipment. But, as you know by now, Gaster became the Royal Scientist. He had the disposal of everything he could need. And he's finally done it. The Serif Project is finished."

She was quiet for a few minutes. "Grillby... what does this have to do with me?"

This was the part I didn't want to tell her. "I... by becoming Gaster's assistant, I put you in danger. If I hadn't said anything -"

She shushed me. "If you hadn't said anything, I would have been arrested by the King for looking like a human."

We sat down on a few stools.

She leaned her head on my shoulder and asked, "So, GrillBAE, huh? Where'd you come up with that?"

Dagflabbit...
