this is not connected to the main story at all, just a little side brainrot i couldn’t stop thinking about
anyways… enjoy my mentally unstable couple <3
The office lobby hummed with the quiet energy of quitting time. Sunghoon leaned against the hood of his car, phone in hand, scrolling through messages he'd already read three times. He checked his watch again—7:14 PM. Miyeon was supposed to be out at seven.
Just as he was about to text her, the glass doors slid open. There she was, laughing at something her coworker was saying. Sunghoon's fingers tightened around his phone when he recognized the guy—Minsik from accounting, who always found excuses to talk to Miyeon.
What made his chest tighten was seeing Minsik's hand linger on Miyeon's arm as he spoke, his body angled just a little too close. Miyeon's smile was polite but distant, the one she used when she was being nice but wanted space. Sunghoon knew that smile intimately.
He didn't move. Just watched. Still as a predator observing its territory. The calm before the storm he was about to unleash in the confines of his car.
Finally, Miyeon extracted herself gracefully, waving goodbye as she turned toward the parking lot. When she spotted Sunghoon, her smile transformed into something genuine—the one reserved only for him.
"Sorry I'm late," she said as she reached the passenger door. "Minsik was telling me about—"
Sunghoon didn't respond, just opened her door before she could. His jaw was tight, eyes dark as he slid into the driver's seat. The moment the car doors closed, the silence became thick with everything unsaid.
Miyeon sighed softly, knowing what was coming. She reached over, placing her hand on his thigh. "He was just talking about the quarterly reports, Hoon. Nothing else."
Sunghoon's eyes remained fixed on the road as he pulled out of the parking spot. "He touched you."
"It was just—"
"His hand was on your arm for forty-two seconds," Sunghoon interrupted, his voice low. "I counted."
Miyeon's heart stuttered. Of course he had. Sunghoon noticed everything when it came to her. Especially when other men noticed her too.
"He's harmless," she tried, but her voice lacked conviction.
Sunghoon didn't respond until they were stopped at a red light, turning to face her fully. His eyes were dark with something she knew all too well—possessiveness wrapped in vulnerability, jealousy softened by insecurity.
"You're mine, right?" he asked, the question hanging between them like always when this happened.
Instead of answering, Miyeon leaned across the console, pressing her lips to his. The kiss was soft at first, then deepening as Sunghoon's fingers tangled in her hair, pulling her closer. The car horn behind them made them jump apart, the light having turned green.
Sunghoon accelerated through the intersection, his knuckles white on the steering wheel. "Not here," he said, his voice rough. "Home."
The rest of the drive passed in charged silence. When they finally pulled into his garage, Sunghoon killed the engine but didn't move to get out. He turned to her, eyes searching hers in the dim light.
"Sometimes I wonder," he started, then stopped himself, shaking his head. "Never mind."
"Say it," Miyeon urged softly.
"I wonder if you'd leave me for someone normal," he admitted quietly. "Someone you don't have to hide."
Miyeon's heart ached. For all his quiet confidence, Sunghoon carried this insecurity—their secret relationship, her being his best friend's little sister, the sneaking around—it wore on him more than he let on.
She undid her seatbelt and climbed into his lap, straddling him in the driver's seat. The position was awkward, intimate, perfect.
"Look at me," she commanded gently, tilting his chin up until their eyes met. "There is no one else. There's never been anyone else that made me feel like this. That makes me feel safe and wanted and—"
She was cut off by his mouth crashing against hers, hungry and desperate. His hands roamed her back, pulling her impossibly closer as if she might disappear. The kiss was messy, emotional, everything they couldn't show the world.
"Miyeon," he breathed against her lips, his voice ragged. "I need you."
"I'm right here," she promised, sealing her words with another kiss. "Always."
His fingers slipped under her blouse, tracing the skin of her waist. "Sometimes I hate that I can't take you on proper dates. Can't hold your hand in public. Can't tell anyone how much I love you."
"We have this," she whispered, rocking against him. "This is ours."
Sunghoon's eyes closed, his forehead resting against hers. "I'm sorry I get like this."
"Don't be," she replied softly. "I'd rather have your jealous possessiveness than indifference any day."
A small smile touched his lips. "Even when I'm being an idiot?"
"Especially then," she teased, then sobered. "But you know you have nothing to worry about, right?"
His gaze intensified. "Do I?"
Instead of answering with words, Miyeon showed him. Her hands moved to his belt buckle, deftly undoing it as her lips found that sensitive spot just below his ear. Sunghoon's breath hitched, his hands gripping her hips.
"Here?" he asked, even as he adjusted his seat to give them more room.
"Right here," she confirmed, her voice husky with desire. "Right now."
"You're killing me," he whispered, turning to look at her. His voice was wrecked, thick with want. "Just... get in the backseat."
Miyeon didn't ask questions. She scrambled over the center console, her skirt riding up as she moved, and dropped into the darkened backseat just as Sunghoon killed the lights.
The garage door was already down, plunging them into near darkness, save for the faint glow from the streetlights filtering through the vents. The air smelled of expensive leather and the sudden, heavy tension of two people starved for each other.
Sunghoon didn't hesitate. He kicked the door open and followed her in, collapsing onto the seat beside her. The movement jolted the car, but he didn't care. He pulled her against him, his lips crashing down on hers with a desperate, hungry intensity that took her breath away.
"Mmh—Hoon," she gasped against his mouth.
"Mine," he mumbled against her lips, his hands roaming frantically under her top, his palms burning a path across her skin. "You have no idea how much I needed this."
His usually composed, cool exterior was completely shattered; he was a mess of trembling hands and ragged breathing, worshipping her body like she was made of glass and starlight. He kissed her neck, his tongue tracing the rapid pulse in her throat, nipping gently at the sensitive skin, drawing a soft moan from her lips.
"God, Miyeon," he groaned, his voice rough. "You smell so good."
He pushed her back against the seat, spreading her legs with his knees, his hands sliding up her thighs to cup her through her panties. The fabric was damp, and the contact made them both shudder.
"Look at me," Sunghoon commanded softly, his fingers hooking into the waistband. "I want to see you when I make you come."
Miyeon nodded, her eyes fluttering open to meet his dark, intense gaze. He was gentle in his dominance, but the desperation in his eyes made him terrifyingly effective.
He slid her panties aside, his thumb circling her clit with agonizing precision. "You're so wet for me," he whispered reverently, as if he were admiring a masterpiece. "Do you know what you do to me? Every time you smile, I get hard. Every time you laugh..."
He lowered his head between her thighs, his breath hot against her skin. "I'm going to eat you alive, Miyeon. I'm going to memorize the taste of you."
He didn't give her time to adjust. He kneeled down in the cramped space. His mouth was on her immediately, his tongue licking a bold, wet line from her entrance to her clit. Miyeon cried out, her back arching off the leather seat, her hands tangling in his dark hair.
Sunghoon worshipped her. He treated her body like the most precious thing in the world, his tongue and fingers working her with a focused, desperate rhythm that had her seeing stars. He made little sounds of approval against her skin, humming as he tasted her, as if he were starving and she was the only food that would satisfy him.
"Please," she begged, her legs trembling around his shoulders. "Hoon, please."
Sunghoon groaned, the sound vibrating against her thigh as he pulled back just enough to catch his breath. His eyes were dark, dilated, completely consumed by her. He looked wrecked, just like she felt, and the sight of him—flushed, hair messy, lips glistening from her—almost made her come again.
"God, Miyeon," he breathed, his voice rough with unshed desire. "You taste like heaven."
He didn't give her time to recover. He got up and sat himself on the seat, pulling her on his lap while pulling out a condom from his back pocket. His hands trembled as he finally undid his belt and pushed his pants and boxers down just enough to free himself. He rolled on a condom with clumsy, desperate fingers, and Miyeon watched him, her chest heaving.
He positioned himself between her thighs, his hands bracketing her head as he leaned down. The car smelled of them now—her arousal and his scent, musky and overwhelming.
"I'm going to be so good to you," he promised, his forehead resting against hers. "I promise. Just tell me what you need."
"Need you," she choked out. "Need you inside me."
Sunghoon smiled—a small, tender expression that made his face look boyish before it was overtaken by the heat in his gaze. He guided himself to her entrance, the tip nudging against her wetness. He was big, heavy and thick, and the stretch as he pushed in was deliciously painful.
He pushed slowly, inch by agonizing inch, watching her face the entire time. "You're so tight," he whispered reverently. "So perfect. I'm going to memorize every inch of you, Miyeon. Every curve, every sound, every way you squeeze me."
When he was fully seated, buried deep inside her, they both froze, trying to catch their breath. Sunghoon rested his forehead against hers, his hands tracing her jaw, her neck, her collarbone, as if he was afraid to touch her too roughly.
"You feel so good," he murmured, his hips twitching slightly, testing the waters.
Then he began to move. Slowly. Deeply. He wasn't rushing; he was worshiping her body, treating her like the fragile, precious thing she was to him. Each thrust was measured, hitting her exactly where she needed it, sending sparks of pleasure shooting through her spine.
"You're mine," he said again, his voice dropping to a growl as he picked up the pace just a fraction, his hips rocking against hers with a steady, relentless rhythm. "No one else can see you like this. No one else can hear you sound like this."
Miyeon's hands clawed at his back, her nails digging into his skin as she arched up to meet him. "Hoon—" she gasped, her head falling back against the seat. "Yes, just like that."
He leaned down to capture her mouth, swallowing her cries, his tongue tangling with hers in a desperate, messy kiss. He kissed her like he was starving, like she was the only thing that mattered in the world. His hands roamed her body, squeezing her breasts, tracing the lines of her waist, memorizing her.
"You're so beautiful," he breathed against her lips. "You're so beautiful when you look at me like that."
He reached between them, his fingers finding her clit again, rubbing it in time with his thrusts. "Come for me, Miyeon. I want to see you fall apart."
The added friction was too much. Miyeon’s vision blurred, her back bowing off the leather seat as she shattered around him. Her walls clenched tight around his cock, milking him, and Sunghoon hissed, his hips snapping forward one last time.
"Mine," he roared, his hands gripping her hips tightly as he came, filling her up with hot, heavy bursts of release. He stilled, his forehead resting on her shoulder, his body shaking as he rode out his orgasm.
He held her close, burying his face in the crook of her neck, taking deep, shaky breaths as he held her. "I love you," he whispered against her skin, his voice thick with emotion. "So much. You have no idea how much I love you."
"I know," she whispered back, running her fingers through his hair, tugging gently. "And I love you too, you big baby."
Sunghoon lifted his head, his eyes soft and loving as he looked at her. He kissed her forehead, her nose, her lips, all with a tenderness that made her heart swell.
"You're everything," he said softly. "Everything."
The windows of the car began to fog as they lost themselves in each other, secret touches and whispered promises filling the small space. Outside, the world went on unaware, but inside their little bubble, there was only Sunghoon and Miyeon and the certainty that they belonged to each other completely.
The car was filled with the quiet sounds of their heavy breathing, the only proof of what had just happened. Sunghoon pulled out slowly, and Miyeon winced slightly at the sensation of emptiness. Sunghoon noticed instantly. He didn't pull away completely; he held her close, pressing soft, apologetic kisses to her shoulder as he grabbed the tissues from the glove compartment.
"I'm sorry," he murmured, his voice thick with regret. "Was I too rough? Did I hurt you?"
He cleaned her with careful, deliberate motions, his eyes never leaving her face, as if checking for any sign of distress. His thumb brushed over her cheekbone, his touch feather-light. "You're so sensitive," he whispered reverently. "You're so perfect for me."
He discarded the soiled tissue and pulled her back against his chest, wrapping his arms around her waist. He buried his face in the crook of her neck, inhaling her scent deeply, like a man marking his territory.
Later, as they lay tangled in the back seat, Miyeon traced patterns on Sunghoon's chest.
"You know," she said softly, "if you ever feel insecure, you could just kiss me like that instead of getting all quiet and broody."
Sunghoon's arms tightened around her. "I'll keep that in mind."
"Good," she murmured, pressing a kiss to his collarbone. "Because you're mine too, Park Sunghoon. Remember that."
His response was a soft kiss to her forehead, then her lips, then her neck—worshipping her as he always did when his heart felt too full of emotion to contain.
"Always," he whispered against her skin. "Always yours."
"I could stay here like this forever," he sighed, his hands stroking her sides in slow, soothing circles. "Just you and me in the dark. No one else."
Miyeon in his arms, her fingers tangling in his sweaty hair as she looked up at him. "I wouldn't want to be anywhere else," she said softly.
Sunghoon kissed her again, slow and deep, tasting himself on her lips. It was messy and affectionate, a quiet acknowledgment of everything they shared. When he pulled back, he looked at her with such intense adoration it made her heart ache.
"You're my everything," he said, his voice barely a whisper. "I'd burn the world down just to keep you safe. Just to keep you mine."
He helped her rearrange her clothes, his hands lingering on her hips, her waist, before pulling his own pants back up. The car was still dark, the silence between them heavy but comfortable.
"You've got marks on your neck," he murmured, his finger tracing the hickey he'd left there a while ago. "And on your shoulder. I should have been more careful."
Sunghoon reached up to kiss the spot gently, a soft, chaste kiss that spoke volumes. "But I like them," he confessed. "They're proof. Proof that you're mine."
He opened the car door and stepped out, offering her his hand to help her up. As she climbed out, he kept a firm grip on her hand, his fingers interlacing with hers, refusing to let go.
"Come on," he said, leading her toward the house. "Let's get you warmed up. And then," he glanced at her with a wicked, possessive glint in his eyes, "I'm never letting you go to work alone again."
Miyeon squeezed his hand, a smile playing on her lips. "Deal."
They walked inside, the two of them connected by touch, hearts racing, and secrets kept safe in the dark.
