A marionette's dance (Yandere!ShalnarkXreader

A long week

Did you know that cats mimic the frequency of human babies to appeal to the subconscious maternal instinct of those who hear it? That's all he was. Something mimicking humanity to appeal to your senses. He set his eyes on you back in Meteor city. He made you feel as if you were equal, that you had your own free will and chose to be with someone as perfect as him. It was all a lie. He was a hunter and you were his victim, falling oh so willingly into the honeytrap he put forth. He lured you in with jewels and words and assertions of his devotion. He caught you in the saccharine melodies he produced and the soft songs that warmed cold nights. You truly believed the relationship was love and maybe it once had been, but it had twisted into a smothering obsession that drowned in the depths of deception. There was no lock but you had stayed in that gilded cage, believing that you may somehow salvage the relationship that had saved your life. It was only with the wool ripped dreadfully from your eyes that you realised you were too late.

  “Were you listening?” 
You jolted and brought your hazy eyes to the man sitting in the chair. He sighed and stood.
“Are you not willing to talk?”
You simply remained silent, resisting the urge to scream at the murderer who had trapped you here. You wouldn't give him the satisfaction of hearing your voice. This had become a regular occurrence. Every day at noon, he would bring you something to eat and sit in your desk chair. He would speak about his day and plans for your future together, not noticing your disdain towards the killer. You weren't sure how many days had passed but your protestations and outcries were met with silence so you decided to return the favour. For the first few days, you would do anything to get out.  You would carve at the walls, bang on the door, and scream at the top of your lungs for someone to hear you for hours on end. It was all futile. The walls were reinforced, there were no windows, nothing in your possessions led you any closer to finding a way out, and the large metal door was weighted and mechanical with nowhere to pick the lock. Eventually, you decided to wait until he got bored.

  “I missed you, you know? It broke my heart that you would abandon me after all I had done for you.”  He paused for you to speak but you kept your lips sealed.
His eyes showed sadness but you quickly suppressed the urge to comfort him. Although being knocked unconscious is shown as a simple nap that ends perfectly fine in most films, being unconscious for more than a few seconds can result in neurological issues. Maybe that's why you had more and more of these thoughts. You jolted as he ran a hand through your hair, not having noticed when he got so close. He pulled his hand back slowly and you rushed away from his calm visage. He looked hurt that you would react so viciously to such a small action but you knew better. It was nothing but a trick.
“I know you still love me. I love you too. You just need some time.”
Did he think that this was love? He was delusional.
He gave you one last longing look and spoke “I have a mission and I'll be gone for the next few weeks. That was what I was trying to tell you. I’ll leave you some food but I won't be able to visit.”
He tossed an old brick-like device onto the desk.
  “It's a phone. You'll be able to call me from it and I'll check in on you occasionally. Got it?”
A phone? Maybe he was dumber than you gave him credit for. You nodded quickly, hands already itching to dial the hunters association and get out, and he smiled at you.

  You decided to wait to call. If he was telling the truth, then he would leave soon enough and if you called when he was gone, the hunters association could get you safer. Anticipation racked your body in shivers as you stared at the crack under the door and waited for the soft sounds of the radio to disappear. You had noticed that he tended to like music when he worked. Three days, 12 hours, 24 minutes, and 3 seconds. That was how long it took for the music to stop. You haven't slept in the wait. How could you? This was an opportunity to escape and you were going to take it. You waited a few hours more, eyelids heavy from exhaustion and thumb rubbing over the old phone in your pocket, before finally dialling the nine-digit number you hoped would lead you to safety. Three rings greeted your ears before a click signalled the line had been picked up.
“Hello! This is Y/n I've been-'' You froze.
A soft laugh teased you from the line.
“Miss me already? I didn't expect you to call so soon, but it's good to hear from you.”
Shalnark? How? Did you somehow misdial? You hung up quickly and tried a different number. If you called Gon and Killua, then they surely could contact the association. Two rings echoed in your mind, pulse racing.
“Why did you hang up on me?”
You dropped the line again. This had to be a mistake. You dialled for Leorio and only received one ring before the other line picked up. It was silent for a moment. Only for a moment. The grating noise of giggling echoed from the other line and your heart dropped.
“Who were you trying to call? Did you think I would be so dumb as to leave you with an open phone? It doesn't matter what number you dial. I'll always pick up.”
You could hear the smile in his voice and you hung up. You hurled the phone across the room in anger, a glass cup falling with it and shattering on the ground. The device rang and rang and rang. You didn't pick up. You didn't know how long it took for the ringing, an old lullaby from years before, to stop but you set your mind to rid yourself of the little thing. It was useless.
