Reader x Nico || Yandere

(A/N I DECIDED TO MAKE MY DREAM A ONESHOT BUT I HOPE THIS WOULDN'T TURN OUT AS JEFF THE KILLER!)

"So I've been thinking if yandere is actually real.." You wondered.

"Don't even think, (Y/N)! I would die rather than being obsessed by a yandere!!" Piper said disgustingly. "Do you think Jason would become a yandere?"

"I hope not," you said nervously. "Percy just became a yandere...and he killed mortals who got to Annabeth!"

You and Piper saw Jason walking towards you, holding a knife. But unfortunately, there were blood stains. You turned alarmed when you saw him holding a knife. Did he just turn into...a yandere? Or was it just your imagination? You hoped you were wrong.

"HEY JASON!" You greeted. But then, Jason eyed the two of you, you and Piper were so close. But that was just normal, right?

"Stay away from my girl," he unexpectedly growled, holding up his knife.

"W-What?" You stuttered. "Look, I don't like Piper, okay? She's a girl. And I'm not into her!"

"LEAVE HER AND DON'T YOU EVER TOUCH HER!!!" He lunged at you.

"Oh no," Piper whispered. "Run (Y/N)!"

And then you ran as fast as you could. You turned your head at the back and saw Jason pulling Piper and not letting go of her. What was going on right now?! Was there something like...a Yandere Virus?

Suddenly you bumped onto someone. And it was Nico. You suddenly hugged him, "NICO! JASON ALSO TURNED INTO A YANDERE!" You screamed. "He was about to kill me that time because he thought I like Piper!" You pulled away and looked into his obsidian eyes. He was gazing down at you, brushing his fingers through the strands of your (h/c) hair. He slightly smiled and wrapped a finger around your waist. You startled. "N-Nico?"

"Now you're mine," he smirked.

"Wait.." You tried to push him away but his arm was wrapped tight and you couldn't move. "Nico—get away from me!" You gasped.

"No." He growled.

"LEAVE ME ALONE!" You screamed. You saw Leo and Will coming towards the two of you. "HELP!"

"(Y/N)!" They exclaimed and ran towards you. Nico let you go and unbelievably, killed them. He pulled his Stygian iron sword and stabbed the two of them into their stomachs. He smiled evilly. "No one touches my love," he growled, putting his sword back into its sheath, even if it had blood stains dripping off.

You ran as fast as you could, but Nico was faster than you ever expected. He pulled you to him and wrapped his arm around your waist, shadow-traveling to the underworld, where his father Hades lived. You have no choice, the Underworld was very dark, and you couldn't escape this place. Nobody had escaped this domain except for Hercules and other ancient heroes.

"Nico please," you sobbed. "Let go of me..."

"You're mine now. And no one will ever get you from me. I love you (Y/N)," he whispered to your ear. You felt so much shiver. You saw him smirking in the darkness.

"Just let me go..." You whispered.

"No (Y/N), you're only mine," he pulled you closer as he teleported to the palace. Then all of a sudden he let go of you.

You tried to run, but he held on your wrist. "You can't escape. You'll be in here forever (Y/N)." He grinned and disappeared. "I'll just be watching over you."

You shivered as you heard the last sentence he said. Him watching over you? Well that was very creepy. You start to walk around, darkness almost overcasting you. You wanted to get out of here. But just like what Nico said, there's no way out.

"Why...is he so cruel??" You felt tears run out of your eyes. You had never expected that even, your crush, would turn into a yandere. You sat on a grassy area, seeing ghosts pass by and look at you. But you're not afraid. They're just beings who existed.

But then, here, your crush, so obsessed of you right now, killing people cause he thought they would get you, claiming you as his own property, and being so demanding towards you? How could a kind, cute, and a son of Hades, nearly treated as a prince could be so cruel and a killer?

"Look...Nico," you whispered. You thought he wouldn't hear anything you would say. But it was just right that he had heard that. "I...I have a crush on you...for a very long time..." You looked around, making sure no one was watching.

You sighed deeply. "It's just that I—I was scared of telling you. You know—you're very quiet and serious, not even making a single, tiny smile. Nico—I was about to tell you but...this yandere thing just spread out like wildfire..."

Right after you remained silent, pulling your knees up to your body and resting your head with your arms on your knees. It took almost a second when you felt someone rest its hand on your shoulder. You looked up and saw that it was Nico. You immediately looked away. You thought he would pick you up absurdly, shoving you and not letting you go.

But instead, he crouched down and stared at you with his beautiful obsidian eyes, gazing at you like you had never seen before. "You...like me?" He asked, probably not believing on what you said.

You nodded, whispering a "Yes...but...it was too late...you turned into a yandere before I even—confess my feelings to you........"

"I'm...I'm so sorry," he pulled you gently to his chest and hugged you, resting his head on top of my head. He held your hand as he softly stroked his fingers on your cheeks with his other hand. "I thought you would never like me...but I was wrong (Y/N). You really like me. And I'm really sorry again..." He sighed.

"I—I just hope that yandere virus would disappear...I don't want people being killed, especially by my friends, and you." You said.

You looked up to meet his obsidian eyes, where he looked back to your (e/c) ones. But you'd never expected that he would place his lips on your soft ones.
