Reader discretion is heavily advised.
Before your paths crossed, he was less of a person and more of a localized urban legend. He wasn’t a criminal mastermind executing calculated heists. Instead, he was a walking, breathing seismic event, the kind of untamed force who would tear down a chain-link fence with his bare hands just because the metallic rattling agitated his overstimulated brain. The neighborhood knew to clear the sidewalk whenever his massive, heavily scarred frame appeared in the dim streetlights. He was volatile, deeply unpredictable, and known for surviving street fights that would have put anyone else in the ground.
You, by contrast, are someone who feels entirely crushed by the sheer weight of the city. Your severe anxiety makes the world feel incredibly loud and aggressive. The screeching train brakes, the glaring neon signs, and the transactional apathy of the crowd keep your nervous system in a state of permanent exhaustion. You spend your life trying to blend into the brickwork, keeping your head low and hoping the city passes you by without noticing.
Your first encounter wasn't during one of his typical chaotic rampages. It happened during a moment of rare, shattering vulnerability that no one else had ever witnessed. You were taking a shortcut through a quiet, forgotten alleyway behind an old theater when you stumbled upon him. He wasn't fighting. He was completely collapsed against a damp brick wall, his chest heaving in shallow, ragged gasps as he suffered a severe, blinding panic attack of his own. His usual terrifying aura was gone, replaced by a desperate, suffocating helplessness as he clawed at his own throat, suffocating in his own mind. Instead of running away from the neighborhood monster, your own experience with panic kicked in. You instinctively knelt in the dirt right beside him, completely bypassing your own fear. You didn't crowd him. You just sat there in the quiet alley, softly counting your breaths aloud and holding a clean, cold bottle of water out to him until his vision cleared and his heart rate stabilized. To you, it was just basic human empathy for a soul in torment. To him, you were the first person to ever look at his pain without a weapon in hand.
The moment he recovered, his fractured mind completely rewired itself around your existence. The rabid, bloodthirsty persona he shows the rest of the world completely dissolves the moment he tracks you down. Around you, he transforms into an intensely physical, shadow-like protector who treats your presence like holy ground. He has zero concept of personal space. He loves sitting flat on the floor right beside your chair, leaning the heavy weight of his shoulder against your knees, and softly tracing the fabric of your sleeves just to ground himself. "Hey... look at this. I found a vintage pocket watch in an abandoned car dashboard. It still ticks. It’s for you. If anyone tries to steal it, I’ll take their fingers off."
Because he knows the city terrifies you, he uses his erratic street-smarts to create a bizarre version of luxury for your small apartment. He has an uncanny ability to source high-end comfort items from the wealthier districts through sheer, chaotic thievery. He’ll randomly present you with things that make absolutely no sense for an outcast to possess, such as an incredibly plush, weighted blanket to help soothe your nighttime panic, imported gourmet teas from a high-end boutique, or a specialized noise-canceling headset he definitely didn't pay for. He will sit on your floorboards, completely blocking your view of the entryway, and meticulously prepare things for you, watching your face with intense, wide-eyed fascination to ensure your anxiety is fading.
Your few family members and friends are entirely horrified by his total hyper-fixation on you, and their attempts to intervene always trigger absolute chaos. He doesn't understand casual social boundaries. The exact second a concerned relative tries to pull you away from him to talk in private, his internal switch flips back to pure menace. He will let out a low, guttural growl, bare his teeth, and step directly between you, his massive fists clenching until the bones pop. He turns every family visit or text message into a high-stakes hostage negotiation, effectively isolating your world because no one is brave enough to risk his wrath.
During his worst, most explosive altercations with the local authorities, when he’s backed into a corner by a line of police officers with batons, laughing hysterically with blood dripping down his chin, the only kill-switch to his madness is your voice. The local precinct has begrudgingly realized that pepper spray and tasers only make him more destructive. Instead, they will literally find you and ask you to step onto the scene. The moment his manic, bloodshot eyes lock onto your anxious, trembling form standing on the pavement, the violent tension completely drains from his spine. He will instantly drop whatever weapon he’s holding, offer you a soft, completely unhinged, goofy smile, and walk straight toward you like a scolded pet. "I stopped because you called. See? I'm being good for you. Tell them to leave us alone so we can go home, sweetie."
He has completely transformed your ordinary apartment into a heavily fortified bunker. The local landlords and street gangs give your entire building a wide berth, treating your front door like a cursed threshold. You are still a deeply anxious person living in a harsh world, but the moment he drapes his heavy, scarred arm over your shoulders and pulls you securely against his chest, the entire city seems to go completely silent. He is going to anchor you in his madness forever.
His physical dependency on your touch is absolute and entirely pathological. To him, keeping a piece of his skin pressed against yours is the equivalent of oxygen. Whether you are trying to make coffee, read a book, or organize your space, he insists on being tethered to you. He will walk directly behind you with a warm, heavy palm glued to the small of your back, or he’ll take your hand and obsessively map out the lines of your skin with his rough, calloused fingertips. Even if he’s pacing around your kitchen sink, having a loud, aggressive argument with his own reflection about a neighbor who looked at you through the window, his free hand will remain gently, rhythmically smoothing down your hair to keep his own brain from fracturing.
This constant contact is the only barrier preventing him from tearing the neighborhood apart. The people who live on your floor have noticed a deeply unsettling rule. If he is holding your hand, his demeanor is completely calm, resembling an overly attentive, giant boyfriend. But the exact millisecond that physical connection is broken, even if it's just you letting go to grab your keys out of your bag, his entire posture goes completely rigid. His jaw tics sharply, the light in his eyes vanishes, and a low, animalistic rumble starts in his chest. He will glare at the nearest door or window like a hound waiting to be unleashed until your fingers are safely locked back into his grasp.
He views your frequent panic attacks as an absolute privilege to completely encapsulate you. Whenever a sudden thunderstorm rattles the windowpanes or a loud explosion from a nearby construction site makes you gasp and cover your ears, a dark, intensely satisfied expression washes over his face. He will instantly scoop your fragile body off your feet and pull you into his lap on the floor, wrapping his long, muscular arms around you like a heavy, inescapable cage. He’ll rock you slowly back and forth against the floorboards, burying his face in the crook of your neck and whispering erratic, soothing nonsense to drown out the noise. "Let them make all the noise they want. Don’t look out there. Just look at me. I'm your wall. I'm right here. Just breathe me in."
The midday routine when you try to leave for work is an entirely separate ordeal for the neighborhood. He doesn't understand the concept of a nine-to-five job. To him, you stepping outside without him means you are stepping into a minefield. He will literally sit on your welcome mat like a massive, brooding gargoyle, blocking your exit with his broad shoulders. When you try to squeeze past him, he’ll grab your ankles, completely untroubled by how ridiculous he looks, and whine into your pant legs. "Don't go. Why do you have to go to that building? There are too many people there. Let me come with you. I can sit under your desk. If anyone yells at you, I can bite their kneecaps off. Please, (Y/N)."
If you strictly forbid him from following you to work, he will spend the next eight hours pacing the perimeter of your office building. The security guards have entirely given up on trying to move him along because the last time someone threatened him with pepper spray, he threw a concrete planter through the front lobby glass. Instead, your coworkers will peek out the second-story windows and whisper about the massive, bruised man standing dead-still on the sidewalk below, his unblinking eyes locked entirely on the window of your department. He doesn't pace to look busy; he paces to mark his territory, letting every single commuter know that the person inside belongs to a monster.
The grocery store is another public space he has completely ruined for you. He treats the crowded aisles like an enemy battlefield, walking entirely backward in front of you so he can glare at anyone approaching your shopping cart. If a polite stranger asks you to move out of the way of the dairy section, his entire posture goes rigid. He will step directly into their personal space, his chest puffed out and his fists clenching until his ruined knuckles pop loudly. You have to physically grab the hem of his dirty shirt and pull him away before he escalates it into a physical altercation. He will let you drag him away easily, instantly melting into a pleased, purring mess because you're touching him, but his eyes will stay glued to the stranger until you turn the corner.
He has developed a terrifying, animalistic habit of collecting things that have your scent on them and hoarding them in his designated "spot" in your living room. You started noticing that your worn-out t-shirts, your fabric hair ties, and even your old, empty perfume bottles were completely vanishing from your bedroom. You finally found them tucked behind your couch, arranged into a bizarre, incredibly neat little nest where he curls up when you strictly forbid him from sleeping in your bed. When you confront him about it, holding up a stolen sweater, he doesn't even look guilty. He just grins, his cheeks flushing a faint pink as he wrestles the fabric back out of your hands. "It smells like you. When you’re gone, the air out there smells like garbage and exhaust. I need it so my brain stops shaking. Don't take it back. Let me keep it."
The darkest side of his devotion always peaks when your anxiety hits a breaking point and you try to create physical space. If you lock yourself in the bathroom because you're having a sensory overload and just need to be entirely alone in the dark, his mind completely fractures. He cannot handle a barrier between you. He will sit flat on the floor on the other side of the wooden door, pressing his ear against the wood, anxiously scratching at the paint with his short, jagged fingernails. His voice will drop from his usual playful tease into a raw, trembling whimper that makes you deeply uncomfortable. "Why did you lock it? (Y/N), open it. I can't hear you breathing. Are you dying in there? Did someone get to you through the window? If you don't open this door in three seconds, I'm going to kick it off the frame. Don't separate us. Please. I'll be quiet, I just need to see your eyes."
The late-night routine is where the actual apartment building descends into an absolute circus. Because you try to lock your heavy front deadbolt at 10:00 PM to maintain some kind of boundaries, he is technically supposed to be out on the streets. He isn't. Nobody actually knows how he manages it, whether he manipulates the old fire escape window, slides a stolen plastic card through the latch, or just applies enough quiet, terrifying leverage to click the bolt open. Every single night, he breaks in. He moves through your dark living room like a massive, silent specter, completely ignoring the extra door chains you set up.
Instead of sneaking into your actual bed, he treats the space right outside your bedroom door like a guard post. He will literally drag your heavy living room rug, your throw pillows, and his stolen scent-nest right up against your bedroom doorframe, blocking your exit entirely with his massive body. You’ll wake up in the middle of the night to get a glass of water, crack your door open, and immediately stumble over his sprawling, heavily musked frame. He won't even wake up angry. He'll just groan in his sleep, blindly reach up, and wrap his long arms around your ankles like a giant vine, pulling your feet against his chest while he mumbles happily into your socks.
The middle of the night always evolves into an exhausting neighborhood feud because of his erratic sleeping habits. He is incredibly hyper-vigilant. If a neighbor down the hall walks past your door too loudly or slams their apartment lock at 2:00 AM, he will bolt wide awake in the hallway. He doesn't just ignore it. He will throw your front door open and start pacing the building corridor in nothing but his sweatpants, baring his teeth, snapping his jaws, and loudly cursing at the walls. "Shut your mouths! My person is trying to sleep! They have a headache! If I hear another door slam, I'm ripping the hinges off your entire floor!"
When the furious neighbors inevitably call the landlord or threaten to call the police, he doesn't run away. He just retreats back inside your apartment, locks the door, and throws his entire weight against the frame, laughing maniacally through the wood while the building manager yells from the hallway. He will literally hold the door shut with his bare hands for hours, completely unfazed by the threats, treating the entire conflict like a hilarious game. By the time the sun comes up, the landlord gives up out of pure exhaustion, and he will casually stroll into your kitchen, completely fine, and place a warm, heavy hand right back on your shoulder to help you make coffee as if the entire night had never happened.
