(Reader will have vermillion colored wings. Vermillion is a pretty orange/red mixture. You are also related to Birdtale!Grillby, who is a Phoenix as well. One important fact that needs to be stated, is that human/monster hybrids were also thrown into the Underground.)

BT!Sans' P.O.V.

'The kid hasn't shown up in a while. They've reset about a dozen times now, but I'm glad they've all been pacifist runs. I wonder what's holdin' 'em up?' I ponder, trying to figure out why they haven't arrived. Usually they show up a day after they reset, but it's been two weeks. Nothing's happened. At least I can talk to Tori in the Grove. Speakin' of the Grove, I saw a short, blue clad, skeleton walk out. They were dressed in some kind of armor, but they looked harmless enough. I flew down to the skeleton, only to notice he has no wings. How peculiar.

Maybe he was from another AU? Ink, after saving my AU from Error, told me about these AUs. He looks like he might be from... Underswap? I shrug and approach the skeleton, noticing how similar we look. He's definitely another Sans. No doubt about it. "OH MY STARS! YOU HAVE WINGS?! THAT'S SO COOL!" The little skeleton yells, running behind me to touch my wings. I flinch and move away quickly. "Don't touch them." I tell the skeleton. He looks at me confused, but then replaces that expression with one of shock.

"OH, I'M SORRY! I DIDN'T MEAN TO BE RUDE! I'VE NEVER SEEN A MONSTER, OTHER THAN A BIRD MONSTER, WITH WINGS BEFORE!" I nod. "I-it's alright. Just... Don't ever do that again." The blue clad skeleton nods. "I PROMISE!" I nod and sigh in relief. "You look a lot like me... are you from another AU?" He nods enthusiastically. "YES I AM! I'M FROM UNDERSWAP! YOU CAN CALL ME BLUEBERRY, OR BLUE!" I nod. "Nice to meet ya Blue, the name's Sans, but so's yours. You can call me Bt, or Crow. Whatever tickles yer fancy."

~Timeskip~

Walkin' to Grillby's has become a new normal for me, since Blue can't fly. The random talks we have are actually quite funny. I've grown to enjoy his company these last few months. Since he's new around here, and seems to be just like my brother, I decided to let him stay with us. Papyrus was excited to have a possible friend live with us. They've grown to be pretty good pals, though they make some of the strangest foods when their in the kitchen. Don't get me started on how they taste...

Feeling a tap on my shoulder, I shake my head and look at Blue. "Yeah?" Blue snickered. (You're not you when you're hungry.) "I WAS TRYING TO TELL YOU THAT WE PASSED GRILLBY'S!" My eye sockets widened. "Oh. I guess my head was stuck in the clouds to long." Blue huffed and walked back towards Grillby's. I chuckled and followed him.

Walking in, I immediately noticed a new face. This girl, though she looks human, has these bright vermillion wings. They were glowing in the most brilliant lighting, but I didn't know why. Maybe it's because she was close to Grillby. I didn't know, but she intrigued me, so I decided to go talk to her. As I got closer, I noticed that her wings, much like Grillby's, were made of fire. Out of nowhere, I see Blue come running up to her. "HI! I'M BLUEBERRY, BUT YOU CAN CALL ME BLUE! YOU'RE REALLY PRETTY! WHAT'S YOUR NAME?"

The girl quickly turned to face him and smiled. "Hello there, Blue. It's nice to meet you. My name is (Y/N). Thank you for the compliment. You are quite adorable yourself." I then slowly approach them. "There you are Blue. You rushed off and left me in the dust." Blue then turned to me. "I'M SORRY, CROW!" "Oh, Hiya. Sorry to intrude on your conversation. The name's Sans, but you can call me Crow. I heard your name was (Y/N). Did I hear that right?"

The glowing (E/C) eyed girl smiled and giggled in an adorable manner. "You heard right, Crow. It's nice to meet you as well. So, what brings you to Uncle Grillby's?" I look at her confused. "Uncle? He's your Uncle? I mean, it makes sense with your wings and all, but your half human." She giggles again, Blue looks at her with star eyes and has the biggest grin I've ever seen on his face. "Yeah. My mom was a human and my dad was a phoenix monster and Uncle Grillby's brother."

Blue's P.O.V.

This girl was so pretty! Her smile seemed to shine brighter than the fire of her wings. Oh those wings. They were huge, but looked so delicate. "OH! THAT MAKES SENSE!" I say, getting more and more excited to befriend this girl. "So, why are you guys here? Y'all wanting some food from my Uncle? He makes some mean food." Crow smiled.

"I'll have some, as long as it doesn't bite me." (Y/N) smiled. "Don't worry, our food may be fresh, but it's not that fresh. At least we don't have frozen beef like some places I remember." (I'm talkin' to you McDonalds!) Crow and I laughed. "So, seriously, what're you guys wantin' to eat?" Crow ordered some ketchup and I ordered some fries. When she left with our orders, Crow and I turn to each other. We go and sit at a bar stool and began to talk.

"So, she's new." Crow said, looking towards (Y/N). She was quickly moving around, grabbing different orders and laying them gently in front of each customer, giving them a sweet smile as she left to do the next order. "Her smile is so pretty." I tell Crow. He kept watching her work, as I did, and before we knew it, she was in front of us giving us our food. "Umm... Boys? I've got your orders." She says, waving a hand in front of our faces.

"Oh, um, sorry. I spaced out there." Crow said. (Y/N) giggled. "It's alright. My head gets stuck in the clouds quite often." I huffed and looked away. "Here's your food, Blue. Crow, here's your ketchup." Handing us our stuff, she smiles and walks around the counter. "I've got a couple more orders to take and pass out. Once I'm done, we can talk, ok?"

Narrator's P.O.V.

That was how the skeletons met the sweet, phoenix girl. Becoming close friends with the two, they started to know more about each other. Crow and Blue had found out that, not only was (Y/N) living with Grillby, but she also had lost her parents in the Human/Monster war. Grillby raised her from four years old to her age now. They also found out that she was single. How they came upon that discovery was from a funny game they played. This game was 'Never Have I Ever'.

After months of being friends, Crow and Blue couldn't take it anymore. They've both had a huge crush on her since they met her, if that wasn't obvious enough. Crow would make flirty puns with her and Blue would make her tacos and compliment her. Unbeknownst to them, she felt the same way for them. She was ok with polygamy, meaning she wouldn't mind having more than one boyfriend/husband. (Y/N) just hopes they will be ok with sharing.

Speaking of (Y/N), she's flying over to Crow's house now. Blue and Crow were both sitting on the front steps, waiting for any sign of the girl flying in. "I SEE HER! THERE, THERE! SEE?!" Blue hollers. Crow looks towards the bright reddish color flying towards them. "Yeah, I see her. Let's move so she can land and not hit us on accident." Blue and Crow then move aside, just in time for (Y/N) to land.

Once she landed, the fire on her wings began to disappear and show these beautiful vermillion feathers. She spread them out just to get used to the feeling of feathers again, but then immediately moved them back into their resting position.

Crow and Blue both had similar ideas of what to do today. (Phineas: Hey Ferb! I know what we're gonna do today! Me: Ok, put a sock in it you Dorito chip head. And I'm not talking about Bill Cipher! Bill: I'm not a Dorito! Me: Ok, ok. You're the Illuminati. I don't care. Go away.) They were both planning on confessing. Funny thing is, is that neither of them knew what the other was planning. They both knew that the other had a crush on her, but never did anything to stop one another.

Once everyone is inside, they decide to watch a movie together. This wasn't the first time they've gone on a movie marathon, but this one was different. They decided to watch (Y/F/M/S). Of course she was extremely excited. It was her favorite series! She was slightly surprised the guys wanted to watch it with her, but hey, she's not complaining.

During the movie, (Y/N) started to feel tired. She had worked a really long shift at Grillby's last night and barely got any sleep. Her body then started to lean on Crow, causing her head to lay against his. Blue, who had insisted on sitting in her lap, was being snuggled by the sleepy girl. Quietly, she whispered drowsily to the boys, "Love you, boys."

This floored the two skeletons. She loved, both of them? How was that gonna work? How were they gonna be able to share her? They were say something until they heard quiet snoring. Looking towards the sleeping girl, both of the skeletons shrugged and snuggled into the girl. Feeling the warmth she naturally radiated. Causing them to feel tired as well. "Love you... too." Both the boys said as they too fell asleep.

(Haha! Done as promised! I also killed two birds with one stone. Wait, wrong choice of words. Umm.... I DID IT! I wrote it and it's done! Mwahahaha! Now it's on to the next request! Hope you enjoyed! See ya!)
