The three of them had never really planned for this to happen. Relationships were complicated enough, and adding another person to the mix? Most people would say it didn't work. But somehow, Will, Nico and Y/N fit together like puzzle pieces - imperfect on their own but complete as a whole.

It wasn't always easy.

Will radiated warmth, always with a soft smile and a steady hand. He was the healer, the one who kept everything together when things got tough. Nico was the quiet storm, all sharp edges and hidden tenderness, struggling with weaknesses but fiercely loyal. Y/N? They were somewhere in between, grounding and comforting them both when Will got oo caught up in fixing everyone and when Nico was pulled too deep into the shadows.

But the best moments were the ones that made all the struggles worth it.

---------------

The sun wasn't even setting yet, but the infirmary was empty right now. It had been a long day. Will had been patching up demigods non-stop, Nico had spent hours helping his dad with underworld-related problems and Y/N had been forced to watch kids all day (which was just as exhausting, mind you).

Now, finally, the three of them had a moment of peace.

Y/N was sprawled out on one of the empty infirmary beds, their head resting in Nico's lap while Will sat beside them, absent-mindedly rubbing circles on their arm. Nico ran his fingers through their hair, his touch suprisingly gentle.

"You're gonna fall asleep." Will mumbled, amusement lacing his tine.

"Maybe that's the goal." The child of G/P mumbled, eyes half-lidded. "You two are really comfy."

Nico scoffed, but there was no bite behind it. "I don't think I've ever been called 'comfy' before."

Will grinned. "Guess that's a first then."

"Whatever."

The son of Apollo stretched, letting out a content sigh as he glanced out the window. "I was gonna make us all go stargazing tonight, but I'm starting to think you two would really rather just nap here."

Y/N hummed. "Why not both?"

"We can nap under the stars." Will offered.

"I'm not lying in the grass" Nico deadpanned. "Last time, I woke up with a bug on my face."

"I told you to use a blanket!"

"I thought I'd be fine." Nico grumbled defeatedly.

Y/N snorted. "Classic mistake."

Will nudged him playfully. "So what do you want to do then, Mr di Angelo?"

Nico hesitated. He had never been great at voicing what he wanted, still getting used to the idea that people actually cared enough to listen. But here, with them, he didn't have to overthink it.

"...Actually, I think this is nice."

Will's eyes softened. "Yeah."

Silence settled between them. Not awkward, but comfortable. Y/N sighed contently as they shifted slightly to press closer to Nico's side. Will took their free hand, lacing their fingers together.

"You two should really sleep. I'll wake you up before curfew."

The G/P kid squeezed his hand. "You're the best."

"I know." Will said smugly.

Nico rolled his eyes, but there was the faintest smile on his lips. "You're so annoying."

"I think you mean to say charming."

Y/N chuckled sleepily. "Both."

Will grinned. "I'll take it."

As the infirmary grew quiet again, the warmth of each others presence surrounded them. Nico, too, found his eyelids growing heavy, Y/N's steady breath and Will's soft humming lulling him into rare relaxiation.
