please read !
According to Google Drive, I made this one shot back in September of 2019 JKBSDKJABSD, random fun fact, but this one shot actually came into existence because of Nanny McPhee! 
In the first movie one of the kids says the line, "Don't you know anything about the world? Whoever Daddy marries, is going to vile and vicious, and will treat us like slaves" he brought out his fairy tale book. "Plenty of hard evidence for that" (I created this in 2019, and worked on it a tiny bit in 2020, but aside from that this is entirely from 3 years ago)

I've also added a small note at the end about what was going to happen for this story :3

Also please excuse the weird writing KJSNDKJASKBJD

Will's POV

"Nico.. where are you going?" 8 year old Will Solace asked his Bestest Friend In The Entirely Whole World. 

"Daddy says we have to move." he sadly replied.

"Why?" 

"He says we're getting a new Mommy"

Will smiled, "But that's good!"

Nico frowned at him, "Will. Don't you know anything about the world? Whoever Daddy marries, is going to vile and vicious, and will treat us like slaves" he brought out his fairy tale book. "Plenty of hard evidence for that"

Will's eyes widened, "I - I don't want that to happen!"" 

Nico tried to stay strong, but even Will could see that he was about to cry. "I- I don't want to leave you Will!" he sobbed. 

His own eyes began to water, but he quickly wiped them away so Nico wouldn't get sad. 

"I know! We can get married!" Seeing his confused face he went on, "If we're married you have to stay with me, that way you don't have to move." he smiled proudly and saw the other boy's face brighten up. "Will, that's bwilliant!"

Will thought for a minute, "Hey! My Mom has rings in her treasure chest upstairs. We can use those!" 

Nico smiled in agreement, "When should we do it?" 
"When are you going?"

"In-" he counted on his fingers, "One-two-three-four-six-" "you forgot five" Nico was only a 1st grader so it was normal for him to forget five, Will on the other hand was a 2nd grader."OH, one-two-three-four-si-five-six-seven... eight! We're leaving in 8 days!" he proudly announced. 

Will had some big brain time and finally said, " We'll do it in 4 days! That way they'll have 4 days to think about it. We also have 4 days to plan the wedding" he uwued. 

"It's a plan!" Nico exclaimed excitedly and they shook on it. 

--- 

Over the next 4 days he and Nico planned for the wedding. They invited all of their friends except Octavian because he was mean. Nico said it was better for there to be more witnesses so we let him come. The cake they got was amazing, he and Nico had saved up all their money and taken donations to buy it. Though Will expected that the baker had knocked off some money since it was such a grand event. (Yes Will, that's exactly what she did)

Piper had agreed to take pictures, and said that she'd bring Jason as her date. This was really official. They even made cards by HAND. Everyone had to bring a gift, and we told our parents we wanted to wear our suits to play pretend. They didn't let us have the nice ones though :( 

Nico said his parents were gonna go to the doctors, so we could use the backyard. We pulled out the flowers from Jason's Mom's garden, Jason said it was okay because she pulled them out all the time. Then we put them all around the backyard the day before the wedding. 

Hazel cried when we put her out of the way so Annabeth decided she could be the Flower Girl. 

"But wait... who's gonna walk you to Will?" she asked. 

"What do you mean???" Nico asked confused. 

"When Percy's Mom got married, her uncle walked her to Mr. Paul." 

"Hmm- how about P-" "I'll do it!" an exited voice exclaimed. We all looked behind us to see Jason waving his arms excitedly. 
"Okay, then we've got that done. Piper can stand next to Will, and I'll do the Wedding Words." Annabeth declared. 

"I'm so excited for our Wedding!" Nico giggled, waving his arms around. 

"But you need to have the paper" Percy suddenly said. 

"Paper?? What paper?" Annabeth asked. 

"The one where it says they're married" he said smartly. 

Suddenly Nico jumped up, "OH! Daddy used to have it framed in our room, but then he took if off. We can use that!" 

Leo popped down from the tree, "But that has your Dad's name on it, we can use the copier" Wow, Leo was so smart, he even knew how to use the copy machine. 

And so that was done. 

---Wedding Day---

Piper took pictures whenever she could, including one of each and every guest. 

Octavian walked through the gate in this smart little suit with a golden clip on his tie, "Oh-uhm-Here, stupid" he stammered throwing them a little box. But we couldn't open it yet, Percy said we could do it after the wedding. 

Next was Reyna, she was holding Frank's hand as he tried to walk over to us. "Hazel's over there Frank" Piper told him, and waddled off like the penguin he was. 

They didn't have a red carpet, so they used the plastic roll that Nico's dad used to put on the ground for the kids to eat on as the runway thingy. 

They only food they had to give was the left overs from everyone's yesterday dinner. But they didn't know how to use the microwave so they had to eat it cold. Frank had dropped the cake box from the table upside down. But it was ok, after they'd calmed Nico down they decided to tell everyone is was upside cake. Piper had it once. 

Now was the actual wedding part .No wait, Annabeth needed to use the bathroom, guess we'll have to wait. "JASON. HAZEL'S EATING THE FLOWERS" Leo yelled over the music. They were using Leo's Mom's phone, he said it was for a good cause that he took it. 

Jason ran over and stopped her. Oh look, Annabeth's back. 

She did that weird cough thing, like hehm hehm.

Everyone looked at her except Thalia who was making a paper airplane with her Papa John's napkin. 

"Today we will be here for the u- unif- unification of Nico di Angelo and Will Solace. Everyone stand" She saw everyone do that at Sally's Graduation. "First we will let Will and Nico say something" 

Nico looked at him and smiled at him, eyes sparkling, "I'm so excited to get marriage with you! I love you Will. " he said sincerely. 

"I love you too Nico!" he beamed, but something felt weird in his stomach, for some reason he felt like crying. 

"You will never ever leave each other and not cheat on homework, or get married to someone else. If one of you gets sick the other must stay by your side the entire time. Except if one of you has to use the bathroom. Do you agree??"

"Yes" Will said

"I do?" replied Nico.

" I now pronounce your husbands and w- husband. You may now hug" Annabeth finished sweat on her forehead. 

And then they embraced each other. 

Everyone cheered and we had cake. We almost forgot about the rings until we saw Hazel putting them in her mouth. 

"OH AND WEAR THESE RINGS" Percy yelled. They were really pretty, one was gold and the other was silver. I got the gold one because Nico said I was shiny like the sun. They didn't fit us so Percy and Jason had rolled a bunch of tape around the rim. 

Nico held his hand up to the sky, his smile fading into a frown, "Will. My ring is itching me."

Will examined his own, "Mine is too... After we tell our parents we'll take them off, okay?" 

"Sounds good to me." Nico smiled. 

Suddenly they heard sobbing, "Wha- Jason??? Percy?? Are you guys okay?" Will suddenly asked concerned. Nico pointed, "Look Piper,,, and Octavian are crying too!" 

Percy sobbed into Jason's shoulder, "My babies are growing up."

"Hey!" Jason exclaimed, "I'm the one that walked Will. They were my babies first!"

Annabeth slapped Jason and Percy on their heads, "you guys are both babies too, they can't be your babies."

"Is this Incense?" Leo asked. 

"No Leo! Why do you even know that words?!" Jason asked patting the place where Annabeth had slapped him. 

"I heard my Uncle Tommy saying it." Leo proudly announced.

As I mentioned before this chapter, I wrote this back in 2019, I thought of maybe rewriting / writing an end for it, but ,,, ya know let's just let 2019!ffoodie have this 

Here's what my notes say what was supposed to happen though !
- Despite Will and Nico getting fake married, Nico, of course would still have to move away.
- Years pass, they don't forget about each other and occasionally will call each other on their parent's phone, when they get older they end up talking to each other on Social Media
- The fake wedding thing is something they remember and laugh about 
(either this ^ or they do end up forgetting about each other JKBSKDJB)
- They either both end up moving to the same place, or one of them moves to where the other is for school. They meet up, hang out, a few months later start dating, fast forward to the future, and they're having their actual wedding, Will says something like, "Nico di Angelo, will you marry me for real this time?"
