The transition from a quiet, solitary life to a shared domestic existence had occurred in distinct, unmistakable stages for Cale Henituse.
With Kim Roksoo, the relationship was an exercise in quiet synchronization—a steady rhythm of shared meals, dry observations, and unspoken understanding. With Lee Soohyuk, it was a high-tension, theatrical dance of sharp banter and sudden, breathless moments of absolute security.
But with Choi Jungsoo?
With Choi Jungsoo, the relationship was an inescapable, high-velocity natural disaster.
Jungsoo did not understand the concept of a slow burn. He did not understand boundaries, he did not understand personal space, and he certainly did not understand how to exist in a room without occupying every single square inch of it with his boundless, exhausting vitality.
As a junior in the Traditional Sports and Martial Arts department, Jungsoo spent half his day swinging wooden swords and executing high-impact flips, which apparently translated to having the metabolic output of a miniature sun and the social boundaries of an overexcited golden retriever.
Lately, Jungsoo had developed a shameless new habit: utilizing "studying" or "waiting for Roksoo to finish his shift" as a paper-thin excuse to completely monopolize Cale’s afternoon.
"I'm telling you, Cale-ya, the library is entirely too oppressive today,"
Jungsoo’s voice boomed as he kicked off his sneakers at the entryway, dropping a massive canvas sports bag with a deafening thud.
He was practically vibrating with post-practice adrenaline, his dark hair damp with sweat and his cheeks flushed a healthy, infuriatingly bright pink.
"The air conditioning in the arts building is broken. Roksoo literally kicked me away from his library desk and put on noise-cancelling headphones, and Soohyuk is doing a script read-through. You're my only hope."
Cale, who was currently curled up on the far end of the living room couch with a thick binder of business case studies, didn't even look up.
He merely tightened his grip on his mug of lukewarm tea. "Go away, Jungsoo. I am attempting to calculate corporate tax margins. Your presence is lowering my cognitive efficiency."
"Wow, using big words to hurt my feelings," Jungsoo beamed, completely unfazed. He marched into the living room, stripping off his heavy grey university hoodie to reveal a sleeveless black training shirt that showed off an offensive amount of lean, athletic muscle.
He smelled faintly of cedarwood soap and laundry detergent. Without a single shred of hesitation, he bypassed the empty armchair, bypassed the other end of the couch, and came to a halt directly in front of Cale.
"Move your legs," Jungsoo requested cheerfully.
"No," Cale snapped, his aristocratic mask snapping into place as he glared up through his bangs. "Go sit on the floor like the puppy you are."
Jungsoo didn't argue. He didn't need to. He simply let out a dramatic, exaggerated sigh of physical exhaustion, turned around, and let his entire 180-pound, martial-artist frame collapse backward.
Cale let out a sharp, choked oof as the breath was forcefully driven from his lungs.
Jungsoo didn't just sit; he sprawled his entire upper body directly across Cale’s lap, his long legs dangling off the edge of the cushions while his torso pinned Cale's thighs to the sofa.
He rolled over onto his back, resting his head against the soft fabric of Cale's silk robe, looking up at the sophomore with wide, bright, completely unrepentant eyes.
"Ah, much better," Jungsoo sighed, stretching his arms out over his head. "My spine feels like it’s been put through a meat grinder. We did three hours of high-impact falling drills today. My coach is a sadist, Cale-ya. A literal monster."
"You are a useless dumbass," Cale hissed, his face flaring a brilliant, indignant crimson as he tried to push Jungsoo's heavy shoulders off his lap. It was like trying to move a boulder made of solid muscle.
Jungsoo didn't budge an inch; he merely let his body go entirely limp, increasing his deadweight mass out of pure malice. "Get off me before I poison your protein shakes with laxatives. I am not a mattress."
"You're a very comfortable mattress," Jungsoo corrected, shifting his weight until his head was nestled perfectly against Cale's hip.
He closed his eyes, a content, soft smile spreading across his lips. "And you're warm. Well, actually, your hands are like ice, but your lap is nice."
Cale let out a long, suffering groan, his fingers twitching against the edge of his binder. He considered shoving his textbook directly into Jungsoo’s face, but the sheer absurdity of the situation, and the exhaustion vibrating off the junior's frame made him pause.
Jungsoo's skin was radiating a ridiculous amount of heat, a localized thermal front that was unfortunately very effective at combating the chill Cale had been feeling all afternoon.
With a heavy, dramatic sigh that communicated his profound disappointment in humanity, Cale gave up.
He lifted his thick business binder, balanced it directly on Jungsoo’s broad, firm chest, and used the junior as a literal, makeshift desk. He flipped a page, the sharp snap of the paper echoing in the quiet room.
"If you move and ruin my notes, I will personally ensure Roksoo deletes your gaming save files," Cale warned coldly.
"Deal," Jungsoo murmured, his eyes still closed.
For the next ten minutes, the living room fell into a strange, domestic lull. Cale read his case studies, his pen scratching against the paper balanced on Jungsoo’s sternum.
Jungsoo remained perfectly still, a cooperative piece of furniture, completely content just to exist within Cale's immediate radius.
But Jungsoo was a creature driven by a fundamental need for physical proximity. He didn't just want to be close; he wanted to be touched.
Slowly, almost imperceptibly, Jungsoo began to tilt his head, his messy dark hair brushing against Cale’s stomach. When Cale reached down to turn a page, his fingers accidentally grazed the outer edge of Jungsoo’s ear.
Cale froze. He looked down.
Jungsoo was peeking up at him through long, dark eyelashes, his expression completely stripped of its usual loud, boisterous comedy.
There was a soft, vulnerable yearning in his eyes—the look of a puppy that had been left out in the rain too long and had finally found a warm porch.
Cale knew, through quiet observations shared with Roksoo, that Jungsoo had grown up in a rigid, traditional household where affection was earned through discipline and sword forms, not through soft words or gentle touch. He was starved for it.
Completely, shamelessly touch-deprived.
Cale’s jaw tightened. He wanted to say something sharp, something arrogant to protect his own flustered pride, but the words caught in his throat.
Slowly, deliberately, Cale set his pen down. He lifted his hand, his elegant, pale fingers hesitating for a fraction of a second before he softly sank them into the messy, damp strands of Jungsoo’s dark hair.
He carded his fingers through the thick locks, gently massaging the base of Jungsoo's neck where the muscle was taut from practice.
Jungsoo let out a low, incredibly soft sigh, his eyes closing completely as he leaned his head heavily into the pressure of Cale’s palm.
"You have really good hands, Cale-ya," he whispered, his voice dropping into a sleepy, rough register.
"Shut up and sleep, dumbass," Cale muttered, his own ears burning hot as he continued to gently comb through the dark hair, his heart executing a strange, fluttering rhythm that had absolutely nothing to do with corporate tax margins.
By the time the sun began to dip below the horizon, the temperature in the apartment had dropped significantly.
Roksoo and Soohyuk had texted to say they were caught in a university committee meeting regarding the upcoming campus festival and would be late returning.
The administrative heater in the building hadn't kicked in yet, and Cale—who possessed the cold-tolerance of a tropical plant—was starting to pay the price for his stubborn refusal to go put on a heavier sweater.
He was sitting on the far end of the couch, his knees pulled up to his chest inside his silk robe, his teeth faintly chattering as he tried to focus on his laptop screen. His fingers were stiff, his nose tip a faint, chilly pink.
Jungsoo, who had been dozing on the floor after being kicked off Cale's lap for "over-occupying the jurisdiction," suddenly sat up. He looked at Cale’s curled-up, shivering form, his dark eyes instantly narrowing with immense concern.
"Cale-ya, you're vibrating," Jungsoo observed, standing up. "Are you cold?"
"I am perfectly fine," Cale lied, his voice shivering slightly on the last syllable. "The climate is... acceptable."
"You're a terrible liar," Jungsoo chuckled.
He didn't ask for permission. He didn't offer a blanket. Instead, Jungsoo marched over to the edge of the couch, reached down, and with the effortless, terrifying leverage of a trained martial artist, he scooped Cale up entirely.
"What—put me down!" Cale gasped, his laptop sliding safely onto the cushions as he suddenly found himself lifted into the air like a sack of potatoes.
He flailed his arms, his aristocratic dignity completely evaporating as he swatted at Jungsoo’s broad shoulders. "You brute! You brainless jock! Eviction! I am evicting you tonight!"
"Yeah, yeah, write me a formal notice later," Jungsoo grunted playfully.
He sat down heavily in the middle of the couch, twisting his body until he was leaning back against the armrest, and pulled Cale directly into his lap.
He didn't just hold him; he tucked Cale's back firmly against his own broad, solid chest, wrapping his long, muscular arms securely around Cale’s waist like a human seatbelt.
He pulled his own discarded, thick fleece hoodie over both of them, trapping Cale inside an inescapable cocoon of concentrated warmth.
"There," Jungsoo murmured, his chin resting comfortably on top of Cale’s vibrant red head.
"Human-heated blanket at your service. I run at ninety-eight degrees, Cale-ya. Utilize my resources."
Cale stiffened, his entire body locking up in a state of absolute, flustered panic. He was completely immobilized, his front pressed against the soft fleece of the hoodie and his back pressed against the hard, radiating wall of Jungsoo’s chest.
The scent of cedarwood and pure, vibrant energy completely overwhelmed his senses.
"You are crushing my ribs," Cale hissed, trying to elbow Jungsoo in the stomach.
"I am holding you with exactly fifteen percent of my maximum grip strength," Jungsoo countered smoothly, his chest vibrating against Cale’s back as he let out a low laugh.
"Relax, Cale-ya. You're freezing. Just let me warm you up."
Cale opened his mouth to deliver a devastating, scathing retort about personal autonomy and corporate lawsuits. But then, Jungsoo tightened his arms just a fraction, pulling Cale closer into the hollow of his neck, and the sheer, overwhelming wave of heat finally hit Cale's chilled skin.
It was intoxicatingly warm. It felt like stepping into a hot bath after walking through a blizzard.
Cale’s defensive walls, already weakened by weeks of domestic exposure to these three men, completely crumbled. He let out a soft, involuntary shuddering breath, his tension melting away as his body naturally went soft against Jungsoo’s frame.
He let his head drop backward against Jungsoo’s shoulder, his fingers loosely gripping the junior's forearms where they were locked around his waist.
"You're too loud," Cale muttered weakly, his eyes already growing heavy under the combined influence of the heat and his own chronic exhaustion.
"I'm not even talking," Jungsoo whispered gently, a profound sense of pride and affection washing over his face as he felt the grumpy cat in his arms finally transform into a soft, compliant puddle.
Within five minutes, the steady, rhythmic sound of Cale’s breathing shifted. He let out a tiny, soft snore against the crook of Jungsoo’s neck, completely fast asleep, entirely safe within the hold of his personal human furnace.
Jungsoo just beamed, tightening his hold with absolute tenderness, looking like a golden retriever that had successfully secured the most precious prize in the world.
The real trial, however, occurred at 3:14 AM.
By midnight, the apartment had settled into its final, sleepy state. Because the administrative heater was still malfunctioning, Jungsoo had shamelessly migrated into Cale’s room under the pretense of "ensuring the landlord doesn't freeze to death."
They had gone to bed on opposite sides of the mattress. Cale had strictly demarcated the boundaries, using a rolled-up body pillow as a physical Berlin Wall between his territory and Jungsoo's.
"If you cross the line, I am kicking you into the hallway," Cale had ordered before turning his back.
"Understood, captain," Jungsoo had laughed, curling up under his own blanket.
But Choi Jungsoo was a chaotic sleeper. He didn't just sleep; he practiced martial arts in his dreams, his body constantly seeking out the nearest source of comfort and structural support.
Cale woke up in the dead of night feeling like he was being suffocated by an octopus.
He opened his eyes, staring blankly at the dark ceiling, entirely unable to move. The body pillow had been violently ejected onto the floor. In its place was Choi Jungsoo, who had completely latched onto Cale with a terrifying, subconscious "koala grip."
Jungsoo’s long, heavy leg was thrown entirely over Cale’s thighs, pinning his lower body to the mattress. His thick, muscular arms were wrapped in an iron-clad embrace around Cale’s waist, dragging Cale’s back flush against his chest.
To make matters worse, Jungsoo had buried his entire face into the crook of Cale’s neck, his warm, steady breath puffing directly against the sensitive skin of Cale's collarbone with every inhalation.
"Jungsoo," Cale rasped, his voice rough with sleep.
He immediately tried to pry the massive forearm off his stomach, but it was like trying to break a steel cable. Jungsoo’s muscles instinctively flexed against the resistance, tightening the hold.
Cale wiggled, pushed, and even tried to dig his elbow into Jungsoo's ribs, but the junior merely let out a low, heavy grunt, completely unbothered by the assault.
Realizing it was an absolute losing battle against a man who could swing a sword for six hours without tiring, Cale finally stopped fighting. He let out a long, defeated sigh, his body going completely limp against the hard chest behind him.
He looked toward the dark bedroom door, then around the quiet, shadow-drenched room. Everyone else was asleep. Roksoo and Soohyuk were entirely out cold in their own rooms. No one was looking. No one was here to see him break character.
A rare, incredibly soft smile broke through Cale’s prickly facade. Since he was completely trapped anyway, and since Jungsoo’s chest felt like a literal, premium heating pad against his perennially cold back, Cale decided to allow himself a moment of pure, unfiltered honesty.
Slowly, Cale shifted his weight, turning his head back into the pillows so he could face the giant teddy bear. He let his own hands come up, his elegant fingers lightly tracing up Jungsoo's thick forearm before resting over the bear's large hand.
He leaned his forehead gently against Jungsoo’s broad shoulder, consciously pressing himself deeper into the overwhelming, heavy warmth of the embrace. He let out a quiet, contented hum, completely melting into the cuddle, thoroughly enjoying the feeling of being held so tightly.
Just this once, Cale thought, his eyes fluttering shut as a deep, happy warmth bloomed in his chest. Since he's asleep, I can admit it. I like this stupid brute's warmth.
Then, the chest beneath him suddenly hitched.
Cale’s eyes snapped open in the darkness.
In the dim moonlight filtering through the curtains, Cale found himself staring directly into a pair of wide, completely conscious dark eyes. Jungsoo wasn't asleep.
Cale froze, his entire brain short-circuiting. But instead of the familiar, defensive panic erupting in his chest, the sheer, intoxicating wall of warmth radiating from Jungsoo seemed to dull his reflexes.
Cale felt physically heavy, slow, and utterly helpless in the face of the profound comfort of the hold. He was completely drunk on the warmth.
A deep, treacherous blush erupted across Cale's cheeks, neck, and ears, visible even in the moonlight. But rather than wiggling away, Cale just let out another long, defeated sigh, his eyes half-lidded as he looked back at Jungsoo.
He didn't say a word.
He didn't try to explain himself. He just stayed exactly where he was, nestled against Jungsoo's chest.
Jungsoo’s grin locked in place, his wide eyes filled with absolute, stunned disbelief. He hadn't expected this. He had expected Cale to start hissing and hitting. He hadn't expected this raw, quiet vulnerability.
"Wow," Jungsoo breathed, his voice a rough, awe-struck rumble in the quiet darkness.
He didn't even try to maintain the ruse of sleep anymore; his arms simply tightened securely around Cale's waist, pulling him so close their noses softly brushed together in the dim light.
He didn't tease, and he didn't point out the rare, vulnerable display of affection. Instead, Jungsoo just looked at him with a profound, unwavering reverence, his thumb gently smoothing over Cale's hip to anchor him against his chest.
"Thank you, Cale-ya," Jungsoo whispered, his deep voice carrying a sudden, heavy sincerity.
He didn't need to elaborate. The unspoken depth of the words hung beautifully in the space between them—a quiet, heartfelt gratitude for letting his walls crumble, for trusting him enough to drop the haughty armor, and for simply letting Jungsoo pamper him like this.
Cale’s breath hitched slightly at the raw earnestness in Jungsoo's voice. His ears burned a fierce, hidden crimson against the pillow, but for once, he didn't snap.
He didn't pull away or retreat behind a sharp comment. Instead, Cale let out a long, defeated sigh that melted entirely into Jungsoo’s chest, his fingers lightly curling into the fabric of Jungsoo's shirt as he allowed himself to sink deeper into the protective, grounding warmth of the embrace.
He didn't need to text Roksoo and Soohyuk. Jungsoo just beamed like a proud golden retriever that had successfully secured the most precious, delicate, and surprisingly softest prize in the world, holding Cale close and letting the sweetness of the quiet night wash over them.
When the morning sun finally broke through the curtains at 8:00 AM, the bedroom door slid open with a soft, quiet click.
Kim Roksoo stood in the doorway, holding a mug of coffee, his dark eyes completely flat as he took in the sight before him.
Cale and Jungsoo were completely tangled together like a pair of dropped headphones, Jungsoo’s face still buried in Cale’s neck while Cale’s fingers were loosely curled into the fabric of Jungsoo’s t-shirt.
Lee Soohyuk leaned over Roksoo’s shoulder, a slow, incredibly delighted smirk spreading across his handsome face as he took a sip from his own mug.
"Well, well," Soohyuk whispered smoothly, his dark eyes twinkling with pure entertainment.
"Look at that. Our fierce little prince has been thoroughly captured by the puppy."
"He’s going to be insufferable when he wakes up," Roksoo observed flatly, though the faint, soft curve at the corner of his lips betrayed his amusement.
"He’s going to claim Jungsoo used an illegal martial arts technique to hold him hostage."
"Oh, absolutely," Soohyuk chuckled, gently pulling the door closed to give them privacy.
"But look at his ears, Roksoo-ya. They're pink even while he's asleep. He loves it."
Inside the room, completely oblivious to the older seniors' teasing, Cale shifted slightly under the heavy, comforting weight of Jungsoo’s arm.
He didn't wake up.
He just leaned deeper into the heat, completely content, realizing that no matter how loud, how clumsy, or how invasive the system became, he was exactly where he belonged.
