Burning love(gaster x grillby)

Chapter 1: thinking of him...

Gaster's pov
I sat, looking at my algorithm for the twenty-eighth time. "Why won't you just add up!?" I screamed internally. This was the same algorithm as always that the core was based off... but now...it just didn't make sense... when gaster looked at the math, he couldn't think straight(insert rimshot here), his mind was simply flooded with the thoughts of the fire monster who he chatted with and enjoyed the company of... aka, his coffee supplier, grillby. "Dammit dammit... why...?... m-maybe I just have heat stroke from working in the heat so often... or maybe it's shock from teleporting directly from hotland into Snowden? I can't even tell... I... might have to ask for a break until I can think straight again... yeah... that should help... until then, I'll only hinder the work effort on developing the core and its 'sssp'(seven soul simulation protocol)..." I stood and transported to the kings throne room "s-sire, I know you, the queen and your children are happily awaiting this most pacifistic of abilities of the core but... I've not been able to think straight... I look at the baseline algorithm and see... squiggles of a child drawing on paper... I was wondering if I could have a break until the point of my thoughts realignment..." I spoke thoroughly and pronounced everything as clearly as i was able, I was talking to royalty. "Speak no more, gaster my friend. I have heard your plea and will grant you this time you request. I'd like to suggest talking to a good friend or even to your children about it... young papyrus may just have the ears to pay attention... ehh- figuratively speaking" the kings voice was thick and deep, yet not too deep so as to make him sound intimidating... more like... how cream is in between being milk and being butter.

I sat, admiring how fuku would reach for the machinery as if she wanted to try making coffee like me... I admit, I'm not her father, and I don't know how to take care of a child well but it seemed she partially understood what I do... I mean, hell, this place is a pub and bar, but the coffee here is legit as all hell. I looked at fuku for a moment again and she seemed... hungry?... yes, hungry... I grabbed a piece of coal, one of my favourite snacks, and handed it to fuku... she'd been mentally aging much faster than physically... but the moment i handed her the coal... she held it tightly before dropping it into her flames... then... a bright green flash lit up the bar! And fuku was...standing on her two feet!? Her flames developed a second greenish colour which I assumed marked her from her metamorphosis from baby to child... I already had my colours of fire, ranging from reds, oranges and yellows, to even whites... I hoped deeply that this meant I could have a full blown conversation with her... and we did! After a few minutes of fire crackling, fuku said her first English sentence "papa... can you show me how to make coffee like you do?" I was surprised, how did fuku know of my coffee making, and all the people who buy my recipes I make for them... "how do you... know about that, sweetie?" I asked, curious... "you always talk to yourself about different recipes... three shots of cream for calcium, and a half teaspoon for sweetening... that's one you mention a lot... as well as the name... gaster..." the young fire monster yawned "daddy, I'm tired..." grillby chuckled quietly. He leaned close, picked up fuku and carried her to the break room, placing her on a couch and watching her fall asleep before returning to his bar.

The light of the bar surrounded me as my teleportation was completed... I saw grillby exit the break room "did I get here just on time?" I asked. "No, just helped fuku get to sleep..." he spoke quietly. "Could I see her?" I asked with a slightly excited expression. "Why, of course, gaster... she's had a bit of a... growth spurt, recently though... so don't expect to see a tiny spitfire..." he chuckled as he opened the break room door... I glanced through, seeing a child who looked to be around sans's age(like, thirteen at the time), sleeping on a couch. "Heh... umm... grillby... I'm taking a break from work for a while... I've been really out of it recently... so... I asked asgore if I could... he said yes..." I whispered to grillby... he sighed slightly. "So... you're going to be off work for a while, huh?" He asked. "Yes... then again, I don't remember when I had an actual break..." I sighed, slightly relieved.

"Hey umm... gaster... would you maybe... like to... go out some time?"
