A/N: also this takes place in an AU where Milgram didn’t happen/happen yet/already ended. But there are mentions of some of Haruka’s crimes!~
Taking Haruka to a cat café seemed like a sweet idea at first. Your adorable boyfriend and adorable cats in the same room? What could be cuter? Watching him interact with the fluffy little creatures sounded like the perfect way to spend a date!
But the second you stepped inside, Haruka tensed, his grip tightening on your sleeve.
“Y-Y/N…” Haruka whined softly, his voice barely above a whisper. His eyes darted around anxiously, scanning the room like he was looking for threats. Enemies. That’s what they were. His competition.
And then, his worst fear came true.
The moment you saw a round, fluffy cat lounging by the window, your eyes lit up. “Oh my gosh, Haru-kun, look at this one! It’s so cute!”
You crouched down to pet it, completely entranced.
Haruka’s stomach twisted. His hands curled into fists at his sides. That should be him. You were supposed to be running your fingers through his hair, calling him cute, cooing over him. Not some filthy animal!
His breath hitched as his mind wandered, his thoughts spiraling into dangerous territory. You should be patting his head, cuddling him, whispering sweet things to him—not wasting your affection on some stupid cat. If only he just… if he maybe just—
No. No, he had to be good. Had to be patient. You loved him. You just needed a reminder.
“Awwww who’s a good boy!” You said to the cute cat taking all of your pets.
Good boy Haruka thought… that is what you call him…
“C-Can’t we—c-can’t we just go home?” His voice came out shaky, desperate. “Y/N, p-please?”
You glanced up at him, oblivious to the storm raging inside his mind. “Just a little longer, okay? Here, this one is super fluffy come pet it!~”
You reached out, grabbing his trembling hand and guiding it toward the cat’s soft fur. His breath hitched at the contact—not with the cat, with you. Your touch sent warmth spreading through him, and for a moment, he could almost forget the suffocating jealousy clawing at his chest like cat scratches.
His fingers barely brushed against the cat before he pulled back, his lip trembling. “It’s… i-it’s soft…” he admitted in a mumble.
You giggled. “See? Not so bad, right?”
His stomach twisted again. He didn’t want to see you smile at them. He wanted you to smile at him. Only him.
The second you got home after the cat cafe date and stepped through the front door, Haruka was on you.
You barely had time to take off your shoes before he pressed you against the wall, his arms locking around your waist, a knee between your legs, his entire body trembling against yours. His head buried itself in your chest, his breath hot and shaky against your skin. His fingers laced through yours, pinning them above your head so you couldn’t move.
“W-Why d-do you— why d-do you do this to me, Y/N?” His voice was muffled against you, his grip tightening. “I-It’s not fair… You’re s-supposed to be m-mine… mine…!”
You sighed, in disbelief your boyfriend really got jealous of some fluffy cats you knew he was a bit childish and were used to his tantrums… but this one was different... “Haru—”
“No— N-No, d-don’t t-talk back—!” His voice cracked, desperate. “Y-You spent all d-day p-petting th-those— those things! A-And I was just— I was just s-sitting there—suffering at the cafe table!”
His breath hitched as he buried his face deeper into your chest as tears form in his eyes, inhaling your scent like it was the only thing keeping him grounded. “Y-You’re s-so cruel… y-you’re so cruel… b-but it’s okay… i-it’s okay…” His voice grew softer, a smirk forming on his lips brushing against your neck. “B-Because I know y-you love Haruka the most… right?”
You felt his hands tremble as they trailed down your arms, his lips pressing soft, shaky kisses along your neck. “S-Say it… Say you l-love me… s-say you b-belong to me…”
Your heart pounded nervous if you didn’t comply… he might go back to those cats at the cafe and do something extreme... “I love you, Haru,” you whispered. “More than anything.”
He shuddered.
“I-I love you too, Y/N” His voice cracked, his eyes glistening with tears. “I-I love you s-so much, i-it hurts… I-I w-want— I w-want to give you m-more love— s-so much more—”
His large, shaky hands grabbed yours as he pressed himself closer, his lips brushing against your ear.
“…L-Let’s go to bed, Y/N. L-Let Haruka s-show you how much he l-loves you.”
His smile was soft, sweet, and yet… something about it was utterly terrifying. You felt like you had no choice but to comply to your boyfriend… out of fear he might do what he did to the previous small animals he admitted he did things to when you first started dating… afraid he might see you as a small animal to dispose of next…

Once you two made it to your shared bedroom, Haruka shoved you on the bed, as you fell on it Haruka’s plush rabbit slouched to the side… as if embarrassed to watch.
Haruka's shaking hands reached up to grasp a collar that lay on the bedside table, a red leather band with a heart-shaped charm dangling from it reading “If Lost, Return To Y/N”. You initially got it as a gag gift to tease him for how possessive he was with you… but he was way more into the idea of wearing it than you expected… His face was red and bashful as he held it out towards you.
"P-Put it on me, Y/N... please, put the collar on Haruka..." he whimpered, his voice trembling with need and desperation. "I want to b-be your good boy, your obedient pet... I want to show you how much I love you, h-how much I need you to care for me..."
You were hesitant at first but afraid he might do something extreme if you didn’t comply… So you took the collar from his outstretched hand, Haruka turned his back to you, presenting the nape of his slender neck. He shivered as he felt the cool leather brush against his flesh, a soft gasp escaping his lips.
With trembling fingers from fear, you fastened the collar around his neck, the click of the buckle seeming to echo loudly in the atmosphere of the bedroom. Haruka let out a shuddering sigh, his eyes fluttering closed as he savored the feeling of being claimed, of being yours, having all of your attention on himself… instead of those fluffy creatures from earlier.
Once the collar was secure he turned around and he took a step closer to you, backing you up against your shared bed until your legs hit the mattress.
His hands reached for the hem of his shirt, yanking it over his head in one swift motion. He tossed it carelessly to the floor, revealing his slender torso, the pale skin marred by the bandages and scars of his troubled past. A blush stained his cheeks as he stood before you, his chest heaving with each ragged breath. Only pants and wearing his necklace he always wore around his neck.
He then pulled down your bottoms, throwing the outer garment off to the side and placing your panties on the nearby bedside table… to take care of later…
Then, Haruka's fingers then went to the waistband of his pants, unbuttoning them with shaking hands. He shimmied out of his pants and underwear in one go, kicking them off to the side. Now completely bare, he stood before you, his slim, pale body on full display. His most intimate parts were exposed - his dick, already hard and throbbing with desperate need, jutted out in front of you. It was a testament to his overwhelming desire for you and your attention.
He pushed you down onto the bed, crawling over you with a hunger in his eyes. His hands roamed your body, touching you everywhere, claiming every inch of your skin as his own. He couldn't keep his hands off you, his touch almost frantic in its intensity.
Haruka settled himself between your legs, his hips pressing against yours. He could feel the heat radiating off your core, drawing him in like a magnet. With a low, needy whimper, he reached down and guided his hard, aching cock to your entrance. He rubbed the tip teasingly along your slit, coating himself in your slick arousal.
"Y/N... I n-need to be inside you... I need to f-feel you around me, squeezing me, drenching me in your love..." he panted, his voice strained with desire.
With a sharp thrust of his hips, he pushed forward, the head of his cock popping inside your tight, wet heat. He let out a strangled moan at the sensation, his eyes rolling back slightly. And slowly, inch by inch, he pushed more of himself inside you, stretching you around his thick, throbbing length.
Once he was fully sheathed inside you, he paused, his body trembling with the effort of holding back. He looked down at you, his gaze intense and possessive, obsessive in its love. "Y-You feel... you feel so good, Y/N... so perfect, like you were m-made just for me...”
He began to move, withdrawing until just the tip remained inside you, before slamming back in, burying himself to the hilt. He set a relentless, almost punishing pace, driven by his all-consuming need to remind you he needed your attention most, more than anyone or anything else ever could…
Haruka leaned down to capture your lips in a messy, desperate kiss, his tongue delving into your mouth to tangle with yours. All the while, he never stopped moving his hips, driving into you with force.
As you began to tighten and clench around Haruka's throbbing cock, he let out a guttural moan, his eyes squeezing shut from the exquisite sensation. He could feel your velvet walls fluttering around his sensitive flesh, gripping him like a vice.
"Ah! Y/N, are you... are you close? Are you going to come for me?" Haruka gasped out, his voice strained with exertion and emotion. When you nodded, he slowed his frantic thrusts to a stop, leaving just the tip of his erection nestled inside you.
Haruka reached for a leash you hadn’t noticed on the bedside table. He held it out to you, his eyes filled with a desperate, pleading look.
"P-Please Y/N... attach the leash to my collar..." he begged, his lower lip trembling. "I want to feel you holding me, guiding me, keeping me by your side... I want to be your loyal pet, your good boy who always stays close to you..."
He rolled his hips slightly, grinding his pelvis against yours, his half-hard cock twitching inside your heat. "I need you to pull it, Y/N... pull the leash and show me that you need me too... that I'm yours and I have to obey your every command..."
His other hand reached up to cup your cheek, his thumb brushing over your lower lip. His touch was soft, but there was an undercurrent of possessiveness, of desperation. "Please... please show me that I'm important to you... that I'm the only one you want to be with... forever and ever..."
Haruka's voice broke on the last word, tears welling up in his eyes. He needed this, needed you to reaffirm your claim on him, to prove that he belonged to you completely.
Your cheeks flushed a deep, embarrassed red as you reached out to take the leash from Haruka's shaking hand.
With a shy, nervous smile, you attached the leach to his collar and gave it a gentle tug, just as Haruka had asked. The moment the leather tightened around his neck, a shockwave of ecstasy ripped through his slender body. He let out a choked, desperate moan, his eyes rolling back and his mouth falling open in a silent scream of pleasure.
"Ahhh! Y/N! Yes, yes... I'm your loyal pet, your good boy..." Haruka blurted out, his words slurring together as he lost himself in the overwhelming sensation of finally feeling owned, claimed, loved.
Spurred on by the tug of the leash, Haruka began to move again, his hips snapping forward with renewed vigor. He thrust into you with a frenzied, almost animalistic desperation, the bed creaking beneath the force of his thrusts. The room filled with the obscene sound of skin slapping against skin, punctuated by Haruka's high, breathy moans and whimpers.
As his thrusts grew faster and harder, Haruka's hand found yours on the leash, clasping it tightly. "W-When you come... pull my collar, Y/N... pull it hard and I'll come with you, I promise..." he gasped out, his voice strained and desperate. "I want to f-feel you come first... I want to make you feel good... I want us to come together...!"
He was panting now, sweat dripping down his neck, his hair sticking to his forehead. His eyes were glazed over, staring at you with a fevered intensity as he chased your shared release. He needed it, craved it, like he needed air to breathe. He needed all of your attention.
As you felt your climax approaching, you tightened your grip on the leash and pulled it sharply, just as Haruka had begged you to. The leather dug into the soft skin of his neck as you came undone, your inner walls clenching and fluttering wildly around his pistoning cock.
"H-Haruka! I... I'm coming!" you cried out, your voice echoing off the walls of the bedroom. The sensation of your release triggered his own, and with a final, erratic thrust, Haruka buried himself as deep inside you as possible.
"Y/N! I'm coming too! I'm coming with you!" he shouted, his voice cracking. His hot, thick seed spilled into you, painting your insides with his release. He shuddered and jerked above you, wave after wave of intense pleasure crashing over his body.
In the aftermath of your shared climax, Haruka collapsed against your breasts, his chest heaving and slick with sweat. He nuzzled into your soft mounds, seeking comfort and affection like a needy kitten. His hands roamed over your curves, still desperate to touch and caress every inch of you.
"W-Was I good, Y/N? Was I a good boy for you?" Haruka asked, his voice small and hopeful. He gazed up at you with wide, vulnerable eyes, craving your validation and approval. "Tell me... tell me you like me more than those stupid, annoying fluffy cats at the cafe... Please..."
He sounded so earnest, so desperate for your assurance. His lower lip trembled slightly, and he pressed himself closer to you, if that was even possible. The collar was still tight around his neck, a symbol of your claim on him, your attention all for him.
You wrapped your arms around his shaking form, holding him close and protective, like a precious baby kitten. "Yes, Haruka... you were an incredibly good boy," you murmured, petting his hair soothingly like an owner and their cat. "I like you so much more than those silly cats... I promise, I'll never take you to that place again. You're mine, and I'll keep you safe and by my side, always..."
Haruka let out a shuddering sigh of relief and happiness at your words, his body relaxing completely. He nestled even further into your breasts, his eyes fluttering closed.
He let out a soft, satisfied yawn, his breath evening out as he allowed himself to be cradled in your embrace. His arms wrapped around your waist, clinging to you like a lifeline, like he was afraid you would disappear if he let go.
Within minutes, Haruka's body went limp and heavy in your arms as he drifted off into a deep, dreamless sleep. A small, smile played on his lips, and he looked utterly at peace, like a beautiful, little kitten finally at rest.
You held him close, your fingers combing tenderly through his soft, blue hair. All of your attention devoted to him.
A/N: Hiii~! (´。• ᵕ •。`) ♡ I’m totally obsessed with subby yandere boys who are super neeeeedy and whiny but still have that little dominant side when they’re pushed to their limit~! Haruka from Milgram is literally perrrrrrfect for that, but no one really writes for him (or anyone from Milgram… sobs). Alsooo, I 1000% believe he’s lying about his age and is actually way older but too embarrassed to admit it, so in my eyes, he’s an adult! (*≧ω≦)ゞ Also firrrrrst fic! I write a looooooot but always keep it for myself but Milgram lacks smut so herrrre. Next fic will have Mikoto Kayano, Orekoto, and Haruka together.
