Complicated (Nico x Reader x Percy) Ending: Nico

Nico Di Angelo. Son of Hades and the boy you loved. Now all you needed to do was tell him.

You finally caught up to him while he was on his way to his cabin. You ran after him and shouted, "Nico! Wait!" He barely glanced back before ignoring you and continuing on his way. You just barely caught him by his hand and pulled him to a stop. "Nico please! Just listen to me!", you breathed.
Nico stared, waiting in silence. You sighed with relief and said, "Nico, it's about my... Choice..." After another moment of silence, you decided to just spit it out, considering it didn't look like Nico would be interrupting anytime soon.
"Nico... I choose you... I love you."
The prince of the Underworld blinked. You could almost see the gears turning as he realized what you said. You held your breath, waiting for a reply. Nico reached up to touch your cheek, but he pulled back. He asked hesitantly, "R-really?"
"Yes, Nico. I really love you."
This time, his hand actually connected with your skin. He caressed your face for a moment, staring into your eyes. You noticed he was leaning toward you, and you slowly closed your eyes. For a moment, nothing happened, and you wondered if you were wrong to think he would kiss you. You snapped your eyes open in embarrassment, but as you opened your mouth to apologize, Nico's lips closed the space between you.
This kiss was nothing like the first. It wasn't desperate or fueled by loneliness; It was relief and pure content. Maybe even happiness...
You leaned into the kiss and deepened it. One of Nico's hands still cupped your cheek, but the other started running through your hair as your lips moved in sync. Your hands moved to his chest and you gripped his shirt, loving the feel of his body pressed against yours.
The kiss lasted a few more moments, before you had to pull away for air. His arms moved to wrap around your waist, and as you stared into his eyes, you held his face in your hands. You smiled at him, and he smiled at you. It was a small smile, but it was his eyes that told the true story. They shined with happiness, and it made you smile all the more. You wanted to make him happy for the rest of his life.

Later that day, you ran into Percy by the pegasus stables. You knew you needed to tell him your choice sooner or later, and it would be smarter if you got it over with as quickly as possible.
"Percy! I need to talk to you." He stopped and turned to look at you, "What?" You heard the irritation in his voice, and you knew this wasn't going to go well.
"I-I made my choice..." The son of the sea god stood with narrowed eyes, "And that choice would be...?"
You studied the ground at your feet, before looking up at Percy and quietly saying, "...Nico."
Anger boiled in his sea green eyes. His hand gripped his ballpoint pen, and you thought that he might do something he'd regret. And for a moment, you were worried for Nico. You tried to placate him and quickly added, "Percy! I'm sorry! I just- I-I can't... I'm so so sorry..."
Percy turned and glared at you, but his face softened when he saw fear and guilt in your eyes. The anger melted away, and it was his turn to feel guilty.
"Hey," Percy stepped toward you cautiously, trying not to scare you anymore, "Hey, don't be sorry.You should never be sorry for how you feel. I'm the one who should be sorry. Honestly, I overreacted. And I hope you can forgive me, and that maybe we can be friends again?" The boy smiled hopefully at you, and you couldn't help but smile back.
"I forgive you; and of course I want to be your friend Percy, that's what I've wanted since this all started. I just wanted my friends back." Percy grinned, "Well, you definitely have at least one friend. The other one may not be your friend anymore. He's a bit more than that now, right?" You blushed and lightly shoved the sea prince, "Shut-up!"
Percy laughed and tackled you with a hug. You hugged him back, glad to have your friend again, when you heard a familiar voice shout, "Jackson!" Your eyes widened and you whipped around to see Nico stomping toward the two of you. Percy grimaced and mumbled under his breath, "Uh-oh." Then he raised his hands in surrender and said to Nico, "Hey, man! It's not what it looks like! We were just reconciling our friendship and stuff!" Nico had drawn his Stygian iron sword, and had it pointed at Percy's throat. You quickly stepped in, before your new boyfriend could slice up your renewed friend, "Nico, he's telling the truth. He had no inappropriate intentions, right Percy?" Percy nodded silently, trying to assume an innocent expression. You put your hand on Nico's arm, and he glanced at you questioningly. You smiled reassuringly, and he visibly relaxed. He lowered his sword, and Percy took a deep breath of relief.
Nico sheathed his sword and warned Percy, "Alright Jackson, but I swear to Hades, if you make one move on ____, I'll-"
"Hey, hey. No threat needed. I won't be making any moves at all!" Percy seemed to be trying to imitate a statue, but he just ended up looking stupid. You cracked up, and Nico even cracked a smile. Seeing your expressions, Percy grinned and slung his arms around both of your shoulders.
"So! How about we go get some lunch! I'm starving!"
The three of you walked toward the pavilion together, and you smiled to yourself. Not only did you find the love of your life, you got to keep your two best friends, too. Yep, the future was looking bright.
