Heartstring - y!Cruel King x reader
CW: Soulmate au, swearing, violence
Your travels have taken you through many places. You’ve seen the rocky hillsides of Thieves Den, the arid deserts of Lost Temple, and even the lush valleys of Playground. It was a common question to be asked—why did you travel so often?
You never answered straight because truthfully; you had many reasons. People often liked to guess. Perhaps you were running from a tattered past? Maybe you had dreams of grandeur, and planned to make a name for yourself out in the world. Flattering notions, really.
But most people asked the same thing.
“Are you searching for your Heartstring?” the old woman asked as you handed her a piece of bread. You sighed to yourself, a frown tugging at your lips.
“I…don’t really believe in Heartstrings.” You admitted hesitantly. The woman let out a noise of surprise, pushing her glasses up her nose.
“Oh, my! That can’t be. You really don’t believe?”
“..No, I don’t…” You murmured, scratching the back of your neck.
“You poor thing,” The woman sighed, resting a hand on your shoulder. “One day you’ll find your Heartstring. Never give up, dear.”
“...I was never searching—” You grumbled before shaking your head. “Ah..thanks. I’m sure I’ll…find them.”
“Best of luck to you!” The woman chirped as you continued down the road.
Aah, Heartstrings…an annoying and frivolous concept in your opinion. The idea that there was a spectral string connecting your heart to another seemed…outlandish at best. Ludicrous at worst.
You didn’t like the idea of being tethered to someone. You didn’t like the idea of having your fate predetermined. What if the person on the other end of that string was a monster? Were you just supposed to live like that? In suffering?
You thought not. So you departed from your hometown to live a life of wandering. A life away from the predetermined path so many people thought you were meant to follow.
The sun was dipping behind the horizon now, giving way to a tapestry of stars that painted the sky in little flecks of white and blue. The snow came down in droves, obscuring the path you were following.
The wind picked up, whipping at your face and blowing clouds of snow and ice into the air. You pulled your lantern from your cloak, hoping for the light to guide you through the storm. Somehow the air seemed to thicken, your vision growing less and less until you could barely see the lantern in your hand.
You tried your best to keep walking in a straight line, but it seemed that at some point you had gotten turned around. When the billowing winds of the storm finally petered out, you found yourself standing in front of a large stone gateway.
Lanterns hung on either side of the doors, but above them were two large braziers that stood at the top of the wall. They burned bright, illuminating the kingdom even through the darkness of the night.
There was a group of people at the entrance, slowly filtering through the gates. Curious, you dimmed your lantern and made your way to the crowd. You slipped through without incident, only hearing a guard offer a gruff “Welcome to Blackrock.”
The town was alive, bustling with people from all walks of life. Blackrock wasn’t known for its diversity—in fact they had some of the strictest borders in all of Robloxia—but this was a rare exception.
The North Star festival. One of the only times Blackrock opened its borders to all. Of course, security is also bolstered during this time to ward off any threats that might come through their gates.
Snow showered down lazily from above, the tiny ice crystals latching onto your cloak before melting thanks to your body heat. Your boots clattered over the cobblestone roads, eyes sweeping side to side. Watching as small flocks of children ran through the streets holding candles and loaves of bread.
You quickly stepped out of the way as one ran past, the flame of their candle licking your cloak before being torn away as the child ran further away.
You travelled through the streets, looking at the vendors and festivities with mild interest. Truthfully you hadn’t much care for the festival or its events. You just wanted to find somewhere to stay for the night. Perhaps make some coin while you were at it.
You didn’t have much to offer in the way of goods. Nothing like the delicious smelling street food or the expertly crafted trinkets and charms. Just some dried herbs from your home and some animal pelts you had picked up during your travels.
Your bag was heavy upon your shoulders, but it was a burden you had known for years now. A burden you bore willingly. Even so, there were days when it felt like the weight of the world.
The smell of food dragged you from your thoughts, reminding you that the last meal you had was a handful of rations you ate the day prior. You paused, checking your coin pouch to see only a silver and two copper coins.
In theory it would be enough to buy you something small, but then you wouldn’t have enough to pay for a room at an inn. You sighed to yourself, putting your coins away and continuing down the street.
Guess you’d just have to skip for now.
You doubted anyone here in this prestigious kingdom would have much use for a cluster of dried herbs or an animal pelt. It looked to you that most people were preoccupied with things like jewelry or food.
You turned, deciding it’d be best to just find somewhere to spend the night rather than staying out in the bitter cold. Even with the many bonfires crackling joyously around the city, they did little to stave off the chill that settled in your bones.
Skin collided with metal, causing you to stagger back. You blinked, eyes trailing up to meet the gaze pointed directly at you. Two cyan eyes stared you down, shimmering like snow in the lamplit street.
Your mouth fell open, stammering out something that was almost coherent but utterly falling apart at the seams.
“Y-your majesty—! I—ah, w-was—I’m—sorry—” You withered under the king’s gaze as you stumbled into a clumsy bow. Your boots scraped at the snow covering the cobblestone as your shuffled back.
The king of Blackrock—often referred to as the Cruel King—was nothing short of intimidating. He was a strict ruler with a gaze as cold as his heart. You were honestly a bit surprised to see a man like him roaming the festivities of the town.
He stared at you for what felt like an eternity, standing rigid as a chilling wind blew past you both. You gulped, looking behind you. Why wasn’t he saying anything? Were you going to be executed? You knew the king was cruel, but you didn’t think he’d go that far!
You inhaled, opening your mouth to speak, but the words fell flat on your tongue. You suddenly felt short of breath, like your heart was trying to escape your ribcage.
You clutched your chest, flinching as you looked down to see it glowing a bright cyan blue. “A-ah—w-what–?” You looked up, realizing the king’s chest was glowing as well.
Your throat went dry. You looked eyes with him again, watching his expression shift from annoyance, to shock, to…bashfulness? You took another step back, prompting the king to step forward.
He reached a gloved hand towards you—a silent request. One that you would not fulfill.
You turned on your heels and ran before any words could be spoken. You could hear the shifting of plate as the guards flanking the king stood at attention, then the thundering footsteps of boots on stone as they ran after you.
You took a sharp turn into a nearby alleyway, climbing up the wall to the best of your ability. You rolled onto the roof, uncaring of the snow that stuck to the fabric of your clothes. You sat up, only to be met with a group of guards climbing up the other end of the roof.
You stumbled to your feet, the sharp air stinging your lungs as you panted harder and harder. The guards advanced, the one in front drawing his swords and pointing it at you.
“Come quietly and we won’t hurt you.”
You scrambled away, the wind buffeting your face and nearly pushing you off balance. You recovered, pulling your cloak tighter around your body. “S-stay back!” You shouted over the roaring wind. “I don’t want anything to do with your king!”
The leading knight took another step closer. “His majesty has ordered for your capture. Come quietly or we will have to use force.”
“I didn’t do anything! I’m innocent!” You snapped, swaying slightly as the wind picked up.
“The king has declared you as his Heartstring! It’s your fated duty to be by his side!” Another guard called over the wind.
“No I’m not!” You shouted back, cursing as your chest began to glow once more. You staggered slightly, trying to cover the glow with your arms.
“You can’t just ignore the demands of fate! Come with us now before we have to knock you out!” The guard shouted, approaching once more.
You leaned away, glancing behind you. There was a relatively large snowbank, but it was a long drop. You weren’t sure if you would make it.
But as you looked back at the slowly approaching guards, you realized it was your best option.
You clenched your jaw, inching closer to the edge of the roof. The heels of your boots hung over the ledge as you stood at a draw with the opposing guardsmen. They knew that pushing you further would cause you to fall, but they couldn’t pull back either at risk of you escaping.
You swallowed hard, clenching your teeth. It was now or never.
Small chips of stone scraped against your boots as you leapt, your body twisting in the air as you fell. One of the guards lunged forward, trying to grab your cloak before you fell too far. You undid the clasp around your neck, slipping free of the soft fabric before tumbling down into the snowbank below.
You gasped, stumbling out of the snow and clutching your sides. Without the cloak, you were vulnerable to the bitter chill of the night. You grasped a nearby wall, trying to stop your head from spinning. You had to get out of here before it was too late.
But the moment you took a step, you fell to your knees with a strangled gasp. Your chest exploded with bright blue light, your heart feeling as if it were being torn in two. You doubled over, tears pricking at your eyes as you struggled for air.
Your senses were overwhelmed with the strongest feeling of despair you had ever felt. It was like you were watching everyone you loved get killed one by one while you could do nothing.
It was a horrible feeling. One that left you shaken and too stunned to move. The guards caught up to you after several minutes, all gathering around your trembling form.
“Poor thing…I heard it’s the worst pain in the world trying to run away from your Heartstring..” One of the guards murmured.
“Don’t worry, we’ll get you warmed up in the castle in no time..” Another assured, patting your back.
A third guard wrapped your cloak around your shoulders, gently coaxing you to your feet and supporting you as you were led towards the castle.
All you could do was stumble along numbly, still reeling from the agonizing pain you felt earlier. The guards all noted your pitiful state, tutting softly to themselves.
The king practically sprinted towards you when the guards entered the throne room. He swept you up in his arms, spinning you around before resting his forehead against yours.
He let out a breathless laugh, hugging you tight against his chest. By the time you had thawed out, you were already too wrapped in his grip to do much else than squirm.
“How are you feeling, my Heartstring?” He murmured—voice deep and velvety. You grimaced at the nickname, doing your best to lean away.
“Honestly? Like shit.” You grumbled. “Also don’t call me that.”
The king just stared at you adoringly. Like you were the best thing that ever happened to him. And in a way? You were.
You sighed sharply, finally managing to pry his arms off of you. “Look—can we just forget all this? I’m not your Heartstring or whatever..This is all just a big misunderstanding.”
Then, as if to spite you, your chest began to glow. You grimaced, trying to walk away only to be pulled back by an invisible force. “What the hell—?”
“Heartstrings are tethered to one another.” The king explained, sauntering towards you. “Once the connection is found, it can’t be broken.”
“Oh yeah? And what makes you such an expert on the subject, huh?”
The king just sighed, long and patient. He reached out, gingerly brushing his thumb over your cheek. “Your anger serves as a wall to keep people out.” He whispered, grasping your chin and turning your gaze towards him. “But even the coldest of ice can melt.”
You sneered, jerking away. “Every single one of you is delusional! I’m not going to lay my life down for someone I barely know!” You snapped. “You can’t force me to stay here. I’m leaving.”
You turned around and stormed towards the door. The guards on either side scrambled to block your way, but you never even made it that far. There was a flash of blue in your vision before you suddenly found yourself held against the king’s chest with a dagger to your throat.
The blade was cold—as if it were made of ice. It radiated chill, frost rolling off it in a thin white fog. The king pressed the blade harder into your skin, stopping you dead in your tracks.
“You’re not going anywhere.” He murmured low in your ear. “You’re my Heartstring. If I have to encase you in ice to get you to stay, I will.”
You stopped dead in your tracks, breath trembling as the king gripped you tighter.
“Please…stay.” He whispered, voice softer now. More desperate. “I can’t bear the thought of you leaving anymore.”
You swallowed hard, eyes jumping from the blade to your feet to the door. You counted the guards in the room, felt the tightening grip on your waist, the chilling press of the blade to your skin, and you realized.
You didn’t have a choice.
