Y/N gasps in shock when Stiles suddenly throws Derek across the room. She quickly covers her mouth, staring at her best friend in horror. Stiles sighs and looks at Y/N, a grin spreading across his face. "Y/N. So glad to properly meet you. You look awful."
Y/N winces. With Stiles' not being able to read, having panic attacks, having DRC, disappearing, and now this. She stays awake at night, trying to do something, anything for him. She had dark circles around her eyes, her skin was paler than usual, her hair up in a messy ponytail, and clothes wrinkled.
"I'm Nogitsune, or Void Stiles, but you know that, don't you?" He questions with a light tone, tilting his head to the side. When Y/N didn't answer, he glared. "Don't you?!" His voice booms.
"Yes." Y/N whispers. Allison gently grabs his arms but Y/N immediately moved herself away, looking up at Void. "I know." He grins, pleased with the response.
"Good." Y/N glared at him. "Oh, butterfly, don't look at me like that. It makes my heart flutter." Void raises an eyebrow.
So many things happened, but Y/N was still haunted but the fox demon every day. Sometimes he pretended to be Stiles, just to mess with her. Other times, he was his simple self, tormenting her for his own pleasure.
Y/N never really gave a reaction unless he was aggressive, which was hardly ever. Void stayed gentle with her, only because he knew exactly how she felt about the body he possessed. It was another sick way of toying with her.
"Tell me, Y/N. How much does your heart flutter when you look at me?" Y/N sighs, staring at her math problem. She was catching up on homework, the worst possible time for Void to show up. Of course.
"It doesn't, Void." She informs, writing down a quick equation. Her chair is twisted around, two arms grabbing the armrests and caging her.
"Come on, Y/N! Doesn't your heart beat just a bit faster? Mine sure does. I guess you're just too beautiful for me to handle." His eyes beam. Y/N's eyes widen, her heart skipping a beat.
Suddenly, his gaze turns dark, a sneaky grin on his face. "Liar." She huffs, resting her cheek against her knuckles, elbow pressed against her desk.
"Fine, you got me. I have homework to do, why are you here?" Void chuckles, grabbing her hands and gently pulling her off the seat. He immediately takes her spot, hands moving to her hips and forcing Y/N to sit on his lap. Her legs rested on either side, straddling his lap. Void's arms were wrapped around her waist, holding her steady.
"There, much more comfortable, don't you think?" Y/N glares at him. "Of course it is. Let's play a game, Y/N. I'll tell you a riddle. If you guess wrong, you have to kiss me." Y/N raises an eyebrow.
"No." His grip around her waist tightens.
"I didn't ask a yes or no questions."
"Fine. What's it in for me if I get it correctly?" Void's grin stretches.
"I'll let you talk to Stiles." Y/N's eyes widen. "That's right, beautiful. Get it right, and you get a free pass to talk to Stiles. I promise, it'll be him and not me. I always keep my promises. Deal?" Y/N narrows her eyes.
"Deal."
"Good. Riddle one." His eyes narrow. "I'm tall when I'm young, I'm short when I'm old. What am I?"
Y/N frowns. They remain silent for a moment, staring at each other. "I don't know. And elf?" Void shrugs and snickers.
"Nope, but good answer." Before Y/N could respond, Void's lips are suddenly on her. She tried to pull back but his hand is cupping the back of her neck, holding her in place.
They break for air and Y/N gasps, her eyes snapping open in surprise. Void's eyes are still closed. They slowly opens and Y/N immediately recognizes the brown sparkle. "Stiles?" His eyes widen.
"Y/N! Thank god, you're safe! I thought he was going to hurt you!" Stiles cries, pulling her into a tight hug. Y/N hugs back just as tight, squeezing her eyes shut. "I'm so sorry, Y/N. He's been tormenting you so much. Sometimes, I can't hear what he's saying, but I can still see and your eyes always reveal what you're feeling. I'm so sorry. I can't believe he kissed you."
Stiles pulls back and presses their foreheads together, his shaky hands running through her hair comfortingly. "It's okay. I forgive you. It's okay now." Suddenly, Stiles winces in pain, pressing a hand against his stomach. "What? What's wrong?"
"He's taking control again. Y/N, please, run away. Run far away and don't--." He winces again and Void is back, resting against the seat with a sigh. Y/N narrows her eyes at him.
"Yes, beautiful? Why are you looking at me like that?"
"I lost, yet you still let me see Stiles. Why?" Void grins. His hand rests against her stomach, rubbing soft circles.
"Because your punishment will be worse in the future, little butterfly, and you know it. Tell me, how long have you known now? When did you first start seeing the signs?" Y/N glares at him, tightly grabbing his wrist and slowly removing it away from her stomach.
"I have no idea what you're talking about."
"Don't play stupid, butterfly." Void pulls her close, nearly knocking her forward into him. She quickly stops herself by grabbing the head of the chair, their noses brushing against each other. Void looks down at her lips, earning another glare. "Doesn't matter," He whispers huskily. "Whether you believe it or not, I'm still here. Why else would I show up, my dear butterfly? You've kept me away for so long, but you fell in love and now I'm here."
Void moves past her, his lips brushing against her ear. "I'm going to enjoy ripping you apart, bit by bit. I'm going to drive you insane, break you, before I finally pull your warm, beating heart out of your chest." He laughs, pushing her off of him.
Y/N yelps and drops on the floor, grabbing onto her desk before she got too hurt. She looks up at her chair, seeing it completely empty. His laughter echoing in her head.
