The story of how Annabeth and Percy got together is almost legendary. They shared the best underwater kiss of all time, they held up the sky for each other, and they even saved the world together. Campers tell the newbies about their relationship all the time, embellishing the adventures, acting as if it was some massive struggle of love and loyalty, whereas it's really just a tale of two awkward demigods falling in love.

The story of how Percy ended up having a foursome with his closest friends isn't as popular as the story of him and Annabeth. People think that the magic of the original couple is dashed when two others entered the mix. What they don't know is that the relationship shared by Percy, Annabeth, Rachel, and Nico is much more extraordinary then any variation of Percy's and Annabeth's.

It all started when Nico started to go to the school that was next to Annabeth and Percy's apartment. He would be constantly skipping school and going to the apartment to play Xbox with Percy. They would play video games and watch television all day, and if Annabeth got off of work early, the three of them would make an elaborate dinner together, which usually ended in food fights.

Annabeth was the first to notice how much time Nico was spending in their place. He spent more time in their dinky little apartment then he did at any other place. He even had his own cup at their place, a plate dubbed 'Nico's', and a spare toothbrush. But Annabeth didn't mind, and Percy liked Nico, so she didn't comment on it. It wasn't like it bothered her sex life; she and Percy would still go at it, even if Nico was in the house. They would just be a little quieter than usual.

Percy loved Nico. Maybe a little more then he should have, but Percy wasn't about to point that out. Nico was a great friend and fun to hang around. It was just a bonus that he was such a hot piece of eye candy.

None of them were really sure who decided that Nico should move in. It started when the Hades cabin was having some trouble with the plumbing. Nico asked if he could stay with Percy until the problems were fixed, and Percy was pretty sure that he could fix the plumbing himself, but he just smiled and told Nico that he could stay as long as he wanted.

So Nico stayed at Annabeth's and Percy's, and he just never really left. The plumbing was fixed, but Annabeth told him that he should stay another night- it was wet out and she didn't want him to get hurt. And the next night, Percy said that there was a Harry Potter marathon, and they had to watch it together, so he couldn't leave. And night after night, the three of them made up excuses until they forgot that there was a time when Nico didn't live with them.

None of them really remember when they started to sleep together on a regular basis either. They were drunk the first time, and no one was really sure if any actual sex happened. Neither of the boys felt any new aches in their body, but with Percy, you couldn't really be sure. All they knew was that the three of them woke up in the same bed, clad in sheets, pink hickeys decorating their bodies.

"Well," Nico had said, "We just have to make sure we actually do something next time."

"As long as you guys don't give it to me at the same time. I don't think my body could take it," Annabeth had added, as if they were talking about an everyday thing.

"Yeah," Percy had said dumbly.

And that's how it all started.

Percy really had to marvel at Nico and Annabeth's ability to act as if they didn't wake up in the same bed that morning. They were just acting like usual, Nico drinking unhealthy amounts of coffee and Annabeth frying eggs, humming to herself. But Percy was freaking out inside. Was Nico now his boyfriend? Was Annabeth still his girlfriend? Would he be able to go out on dates with both of them individually? Did they get to out without him?

He frowned faintly at his girlfriend, who was piling eggs on the plate in front of him. Why was she being so normal? How could she not be flipping out right now?

"Uh, no thanks," Nico said to the spoonful of cheesy eggs Annabeth was about to put on his plate.

"Excuse me?" She cocked a hip and gave him a look.

"I don't eat breakfast-"

"Oh, yes you do." She tipped the spoon, spilling eggs onto the ceramic plate.

"No. I don't." Nico scowled at her.

Annabeth gave a gusty breath, sending her blonde hair flying up. She set down the bowl of eggs. "Nico, you really need to eat breakfast to give you energy for the rest of the day. You're a demigod, you really need to be wide awake and alert all day long."

"But I'm not hungry." Nico jutted out his chin, scowling.

A dangerous glint entered Annabeth's eyes, and Percy started to fear for Nico's life.

"Eat the eggs."

"No."

"Eat it! Eat it!" Annabeth demanded, suddenly shoving Nico's head down towards the eggs piled on the plate in front of him.

"No!" wailed Nico, inches away from the food. "I'm not hungry!"

"I don't care!" She pushed his face even closer, and his nose brushed against the eggs.

"Mmph-" Nico sticks his tongue out and swipes a piece into his mouth. "Happy?" He mumbles.

"Very much so," Annabeth lifts her hands off of Nico's abused head. "You better eat the rest of that though," she throws over her shoulder, opening the fridge.

"Percy, she's crazy-" Nico mock whispers.

"I heard that!"

"Well, it's true." Percy tells her, snickering.

She slams the fridge door shut, whirling to face them. "You are so lucky I love you," She tells them both.

"We are," Nico says earnestly.

"I know," She says fondly, briefly cupping Nico's face in her palms, and for the first time, Percy thinks that there's actually a chance that this crazy thing might work out.
