Chapter Text
Felix woke to a dull heaviness pulling him down, not just the light fever but the ache saturating every limb. His throat felt raw, his head hazy, and every shift of his body made his muscles complain. A weight pressed against his forehead. A cooling pad. When his gaze trailed down, he noticed the small device clipped to his finger.
He groaned before he saw him. His professor stepped into view, his presence tall and controlled, almost too composed for the quiet of the room. Without asking, he reached for Felix’s hand, the coolness of his fingers grazing his skin as he unclipped the device. His touch was careful in action, but not in weight. His grip had a firmness that made Felix feel more like an object being inspected than a person being cared for.
“That’s oximeter, for oxygen level,” Hyunjin said simply, his voice a low hum. Then he replaced the thermometer under Felix’s arm, standing over him like he was watching numbers on a screen instead of a human in bed.
When it beeped, Hyunjin didn’t react, didn’t soften, just set it down, reached for the tray on the bedside table, and placed it across Felix’s lap. The faint steam rising from the bowl curled into the air, bland and faintly sweet.
“Eat.”
Felix blinked at him. “Sir… I don’t like porridge. It tastes like nothing.” His voice was whiny, dragging each word out in lazy defiance. Hyunjin’s stare didn’t change. “Eat,” he repeated, heavier now.
“No.” Felix’s lips tugged into a bratty pout.
That single word fractured the calm. Hyunjin’s jaw tightened, his eyes narrowing just enough to strip the warmth from them. He took the spoon, filled it, and held it steady in the air between them. “I need you to recover fast,” he said, and this time, there was no give in his tone, just exactness. Like he was stating a fact, not making a request.
Need?
What? To fuck me again?
Felix leaned back, ready to make him wait, to force him into giving up first. But Hyunjin moved faster. One hand cupped his jaw, not gently but with a press that made Felix’s teeth ache slightly, forcing his face forward. “Open,” Hyunjin ordered.
Felix kept his lips shut.
The older didn’t blink. The spoon pressed against his mouth, hot metal tapping until Felix’s lips parted just enough for it to slip past. The taste was as dull as he’d imagined, warm and plain. But it was the way Hyunjin pushed it in, firm and unhesitating, that made Felix swallow without thinking.
It kept going. Felix tilting his head away, Hyunjin following, catching his chin, and shoving another spoonful past his lips. Each time, Felix felt like he was being handled by someone who knew exactly how much force to use to make resistance useless. It wasn’t care in the traditional sense… it was like the precision of a kidnapper keeping his hostage alive, feeding him not out of kindness but because it was necessary.
Hyunjin’s breathing stayed even, almost mechanical, his every move calculated. His gaze didn’t wander from Felix’s face, watching each swallow like he was making sure the job was done right.
By the time the bowl was empty, Felix’s lips were slightly damp, his pride bruised. He glared up at Hyunjin, but the other man didn’t seem rattled by it.
The tray was taken away, set aside. Hyunjin leaned in, the shadow of his height falling over Felix. For a second, Felix thought he might say something sharp, something to match the cold edge of earlier… but instead, Hyunjin’s hand came up to cup his cheek. The weight of it was affectionate, heavy, grounding in a way that felt almost wrong after the force from before.
Then he kissed his forehead in all gentleness and warmth, pressing just enough to make Felix feel held still.
“Good job, Lee Felix,” Hyunjin murmured, voice low enough to sink into Felix’s skin. Then he softly landed a butterfly kiss against his lips. Too soft that it was mind boggling.
And Felix hated the heat that bloomed in his chest at those words, hated how much it felt like approval he didn’t want to admit he craved.
By noon, Felix was almost okay but still not fuckable. Lunch was over, the taste of miso soup lingering faintly on his tongue, and he’d already brushed his teeth twice just to feel fresher. Standing in the bathroom, he leaned toward the mirror, studying his reflection critically. His skin was still pale, faint shadows under his eyes betraying the fever from the day before. But his hair was perfect. He ran his fingers through the strands, arranging them exactly like the wanted, every strand falling just right.
When he stepped out into the living room, Hyunjin didn’t look up from the coffee table. His pen scratched against paper in crisp, deliberate strokes. Without prelude, he said, “Let’s review. Prelims tomorrow.”
Shit. Right. I almost forgot about it.
Felix groaned dramatically. “But sir, I’m dropping your class.”
That got Hyunjin’s full attention. His head snapped up, his expression hard. “No.” Just one word. Firm, immovable.
He tried to look like a spark of irritation blooming into something sharper, Felix’s jaw tightened. But when Hyunjin’s eyes met his, and he said a single command: “Sit.”
It wasn’t loud, but it was final. Something in the tone pressed down on Felix’s spine until his feet carried him forward despite himself. He sat in the couch beside Hyunjin, arms crossed like a stubborn child. Hyunjin didn’t waste time. “State the time-dependent Schrödinger equation.”
Making sure he looked cute, Felix slowly pouted, lips pushing out. “Pass.”
“Felix,” Hyunjin’s voice was steady, precise, “I’m not playing here with you.” He asked again, slower this time, like he was speaking to someone easily distracted. “Again. State the time-dependent Schrödinger equation.”
The smaller sighed. “It’s… the thing that tells you how a particle’s state changes over time.”
Hyunjin’s eyes narrowed. “Answer it properly. Not in layman's term.” However, no words were spilled from the student’s lips. “Fine,” Hyunjin murmured as he held Felix’s wrist together with one hand swiftly and rested onto the knee. “Sir, wait—”
“Next, explain the Pauli exclusion principle.”
The blonde threw another boba eyes as he foreced his lips to quiver. Though his mind was oblivious, excitement was beginning to bubble inside of him. Even if his body was still weak and probably be only okay for free use by tomorrow, his head got stiff. The other head. “Two identical particles can’t share the same space—” he took a deep breath when Hyunjin... started pressing his palm over Felix’s crotch. “Uhm… basically, no two electrons can sit in the same chair at the same time.”
“Electrons don’t sit,” Hyunjin said flatly, his hand started kneading against him. The smaller’s mouth slightly ajar to release a small squeak while the older’s face was straight and intimidating. “Answer it as it is.”
“I’m not really ready, sir—uhmmm—I haven't reviewed my notes yet.” He licked his lips to dampen, giving it a glossy finish. The hips he was trying hard to keep still, began moving slightly. Meeting the friction with the older’s long veiny hand, jerking him in fast motion, still clothed. His own hands were still restrained together. He instinctively spread his legs like a fallen angel spreading its wings. Hyunjin didn’t react with Felix's whining. He simply moved on. “What’s the difference between an eigenvalue and an eigenvector in quantum mechanics?”
Felix lowered his head, moaning softly but grinding shamelessly. He was breathing loud through his mouth. “Hmmmm—Eigenvalue is the… answer you get.” Please, remove my pants already... please. He started leaking, underwear getting damped, but Hyunjin’s hand slowed. Leaving his throbbing shaft like abandoned cat at a shelter. The hand moved down to his inner thigh at a frustratingly slow pace. “Eigenvector is the… special direction that doesn’t change shape when you transform it.”
His member started twitching, begging to be held again. It was so uncomfortable and trapped and wet. The younger gulped, breathing miserably. Hyunjin’s eyes were skimming over Felix’s body, smirking as he noticed how needy he was right now. Felix wanted to plead, to kiss Hyunjin, to sit on his lap but Hyunjin’s dark staring eyes made him impossible to move. Like he was not allowed to do anything unless Hyunjin allowed him to.
Everything made him frustrated. As much as he wanted to deny it, he couldn't read Hyunjin's next move. All he could do was anticipate blindly.
“That’s tolerable,” Hyunjin said with his low voice, golden deep, vibrating through his bones. He moved closer to his ear, warm breath brushing against him. His fingers continued scribbling the insides of his trembling thighs. “Sir…” his voice cracked. “Please…”
Hyunjin just tilted his head. He scoffed mockingly. Felix whimpered when Hyunjin pulled his pants down, revealing his already hard pink dick. But the older just watched him. Felix’s eyes were wide, glassy. Lips parted while breathing heavy. Cock was discharging transparent drip desperately.
God, just fucking do the hand job! He wanted to yell but he just fussed, throat getting drier.
Hyunjin then licked his ear, nipping and kissing. Finally stroking Felix's hard member, palm against the sensitive skin. Fingers enveloping his girth, He shuddered altogether. Moaning, shaking, eyes sultry bit still looking innocent as ever.
“What’s the principle of superposition?”
The blonde’s mind was already hazy as he stifled his whines. He couldn’t think straight, no answers were registering to his brain no matter how hard he tried. He rocked his hips pathetically. He was already delirious, hungry, deprived. Then Hyunjin gripped the base of his shaft tightly, making the other gasped audibly. Stopping his pleasures. “…answer me, Felix.”
He looked up, pretending he was thinking hard but he couldn’t stop himself from moaning. Felix bit his lower lip. No words forming, he just wanted to get stroked once more.
The sight of him being helpless again sparked Hyunjin’s eyes. Felix saw how Hyunjin took delight satisfaction when Felix looked like a weak mess, powerless. “I won’t let your cum out until you answer my questions correctly. Principle of superposition, Felix.”
His grip to the length tightened. “It’s when—uhmmm—a system can be in multiple states at once until you look at it… Like being both innocent and guilty until—hmmm… proven otherwise.” He whimpered and shook in between his words.
Hyunjin’s gaze flickered briefly to him at the word “ innocent ,” but he didn’t comment. Hand began caressing him again, suddenly aggressively fast. “State it formally.”
Felix shook his head. Whimpering as he leaned on the couch, hips frantically moving together with Hyunjin’s hand. “Sir, please. Can we continue this later? Please let me come first?”
“No. Last one,” Hyunjin said. His hand gripped his bound wrists tighter while the other relentlessly stroked him. "Oh, my... sir, please... Hngggg—I'm... I'm cu—"
Then he stopped abruptly. Slowly, his hand went from the shiny tip, down to the base, then to the tip again. His pinky finger lazily dragged to the slit, slowly pressing it inside, suspending his pooling precum. “What’s the uncertainty principle?”
He felt his shaft was throbbing, the pinky finger pushing inside. It wade his whole body twitch.
"Sir..." Felix leaned closer to Hyunjin, he didn’t know what he wanted but their faces were close. Too close that he wished Hyunjin would kiss him hard. Parted lips were starving for a sinful taste. Hyunjin's glasses fogged. Tho he just smugly smiled as he moved his handsome face away.
“Uncertainty principle, Felix.” He was impatient. He pumped him slow, earning a defeated sigh from the young one.
The moans began getting louder again the more he felt Hyunjin’s hand pace picked up. “For uncertainty principle… hmmmm… you can’t know where something is and how—how fast it’s moving at the same time.”
Hyunjin fastened the job, cruelly, sending Felix to almost the edge again. He started squirming, eyes fluttering close as he cried wolf, “sir, please… I’m almost there… hngggg—“
“It's position and momentum,” Hyunjin corrected automatically as he let go of Felix’s shaft and hands all at the same time. Freeing him just like that.
“Wait—“ Asshole.
The professor crossed his legs, rested his elbow in it while his palm was holding his chin. The thick glasses sparked when he tilted his head. “Play with yourself.” He commanded sharp.
Felix, looking like an idiot, pants down, hard cock left hanging and exposed, was dumbfounded.
“I said, play with yourself. Come on your own. I’ll watch.” He teased as he widened his eyes, one brow raising. As if casually waiting. As if what he said was not sick at all.
Heat and embarrassment filled Felix’s pale face as he held his own good. Finally, he got to touch himself. To know where he needed to be touched. He gave Hyunjin a show, he just closed his eyes as he got aroused, knowing he was being watched, lusted and wanted.
Damn with his own need for other people's attention to validate his self worth.
His gorgeous face crumpled, grunts were heavier, his pristine skin glowing with sweat. He ejaculated faster, hips naturally moved like he was dancing to his own self rhythm. He was majestic to watch. Like sparkling dust were being thrown against him. Shimmering his soul.
When he slowly opened his eyes, Hyunjin’s face met him, still straight, unreadable. His eyes were hollow but Felix knew he was being desired, so he gave him more. He arched his back, whined more, tremble more. All while their eyes were locked.
Hyunjin’s gaze got stronger, a shard of glass catching light, vicious, unyielding. Felix braced for another mockery. But instead, the hand that rose to his face carried a quiet weight, as if handling something breakable. His palm found Felix’s jaw, a thumb drifted over his mouth with the care one might give to brushing dust from the spine of an ancient book.
Then the kiss came like the fall of a single snowflake. It was light, soundless, and gone too soon to be caught. It carried no hunger, only an aching restraint, and in its gentleness was something far more disarming than cruelty. Felix’s lungs forgot their work. The softness felt wrong against the steel in Hyunjin’s eyes, like a lullaby whispered over the crackle of a fire.
He did it again.
Then Felix came just because he was held so kindly, so tender. It was maddening how Hyunjin could play him like that. His head was having cognitive dissonance. White sticky cum shooting and was caught by his own palm. His bambi eyes could only blink several times out of confusion.
When Hyunjin drew back, his voice was a calm tide pulling him under. “Such a pretty pet.”
Around 3 p.m., Hyunjin lingered in the marble-floored lobby of Tower B, the faint scent of air freshener clinging to the cool, conditioned air. He stood near the corner where the noise of footsteps softened, phone pressed to his ear while running his fingers against his dark tendrils.
“Mrs. Song,” he greeted smoothly when the call connected, his voice carrying that calm, composed authority he could summon at will. “I’m calling about the renovation on Unit 818—the one you’re leasing to Lee Felix.”
A faint rustle came through the line before the older woman answered. “Yes, what about it? I heard the contractor already started?”
Hyunjin’s gaze drifted toward the elevator, watching the numbers change as residents came and went. “That’s what I wanted to discuss,” he said, voice steady, measured. “There’s been… a minor complication with the building’s inspection scheduling. They’ll need to postpone certain repairs for a week or two… just to avoid overlapping with other ongoing works in the wing. If they continue right now, it could cause noise and safety concerns for neighboring units. You know how the building management can be about regulations.”
It was a seamless fabrication, each word polished until it sounded like fact. He leaned against the counter, letting a polite pause stretch just enough for her to accept the story without suspicion.
“Oh,” Mrs. Song murmured, a hint of disappointment in her tone. “Well, I suppose if it’s unavoidable… I’ll inform Felix, though I imagine he won’t like it. I should call Mrs. Lee too so they can find him a place for the mean time.”
Hyunjin smiled faintly, though it didn’t reach his eyes. “Leave that to me, Mrs. Song. I’ll make sure he understands. And I already talked to his mother about it so you don’t have to inform her. We already agreed where to settle Felix until your unit is liveable again. I will inform you once the renovation continues.” His thumb ended the call with quiet finality.
Turning toward the concierge desk, Hyunjin adjusted his cuff, the small gesture accurate and formal. The young concierge looked up, hands resting lightly on the counter.
“Good afternoon, Mr. Hwang,” she greeted.
“I’m checking if the contractor for Unit 818 is still upstairs,” Hyunjin asked, his tone polite but firm enough to make it sound more like confirmation than inquiry.
She glanced at her monitor, tapping through a few keys before nodding. “Yes. They’re still in the unit. At least one worker signed in earlier and hasn’t signed out yet.”
Hyunjin’s lips curved, the expression more calculated than warm. “Thank you,” he said, and without further conversation, he strode toward the elevator.
The doors slid open with a muted chime. Inside, he pressed the button for the eight floor, feeling the faint jolt as the elevator began its ascent. The mirrored walls reflected his composed figure, dark eyes fixed ahead, but his mind was already three steps beyond, imagining the state of Felix’s apartment, the lingering scent of smoke, the misplaced objects contractors never cared about returning properly.
When the doors parted again, the hallway stretched out in muted tones, lined with identical doors and recessed lighting. His shoes made no sound against the tiled floor as he walked.
In his mind, Felix was already living in his condo, had been, for days now and the thought of him moving back here, into this rented unit that still smelled faintly of smoke, was unacceptable. He wasn’t ready to let Felix go. Not to this place. Not yet.
Hyunjin didn’t knock when he reached 818. He simply turned the knob, stepping inside with that same steady, unhurried air, ready to insert himself into whatever scene awaited.
The scent hit first. Charred wood and chemical sealants, mixed with the stale tang of drywall dust. The contractor stood near the stripped wall, clipboard in hand, while two workers crouched beside a half open tool bag. They all looked up at him, pausing mid-motion.
Hyunjin gave them a tight, polite smile, the kind that could pass for neighborly concern. “Good afternoon. I’m here on behalf of Mrs. Song, the owner,” he began, stepping deeper into the room with deliberate ease, his shoes clicking softly against the bare subfloor.
The contractor straightened, shifting his clipboard under one arm. “We were just about to finish the first round of repairs, sir. We will replace the damaged drywall and get the wiring checked. Shouldn’t take too long.”
“That’s the thing,” Hyunjin said, tone dipping into a softer register as though he were reluctantly delivering bad news. “Mrs. Song asked me to speak with you. There’s been a change in the building’s schedule. Some kind of cross-project overlap. Management wants to avoid noise conflicts in this wing.”
The contractor frowned. “But... we already got clearance from the front desk three days ago.”
“I know,” Hyunjin replied smoothly, slipping his hands into his pockets. “But apparently, the unit next door is scheduled for plumbing replacement starting tomorrow. And with the fire damage here, there’s concern about stress on the building’s electrical load while both projects run at the same time. If we push forward now, it could delay both projects indefinitely. Mrs. Song doesn’t want that. Neither does the building.”
He let the words settle in, steady and plausible, each one crafted to sound like it came from a higher authority. The workers exchanged glances, uncertainty passing between them.
The contractor hesitated. “So… you’re saying we have to stop?”
“Not forever,” Hyunjin assured. “Just a week or two. Give the other work a chance to finish, and then you can come back in without any complications. It’s cleaner that way. No conflicts. No fines. No unexpected inspection failures.”
The contractor exhaled through his nose, clearly annoyed but not inclined to argue with what he thought was an official instruction. “Alright. But we’ll need it in writing from the owner.”
Hyunjin smiled faintly. “Mrs. Song will email you by the end of the day.”
The contractor nodded and gestured to the workers, who began gathering their tools. The sound of zippers and clinking metal filled the room as Hyunjin stepped toward the window, his gaze sweeping over the space.
The walls were stripped bare, furniture pushed to one side under protective tarps. Even like this, Hyunjin could see the shadow of Felix’s life here, the faint outline of a painting that used to hang above the couch, the spot in the corner where a small bookshelf had once stood.
He didn’t want Felix back here. Not where the air still carried smoke in its fibers. Not where he could retreat into old routines and distance himself again. At his own place, Hyunjin could watch him, guide him, keep him close where Felix’s little stubbornness couldn’t spiral too far out of control.
The workers filed out one by one, murmuring polite goodbyes as they passed. Hyunjin lingered until the last toolbox was rolled away, the sound of the cart wheels fading into the hallway.
He closed the door behind them, standing in the middle of the gutted living room, the quiet now heavy around him. This had bought him time. A week, maybe two. Enough to make Felix’s return here inconvenient, maybe even unappealing.
Hyunjin allowed himself a small, satisfied breath. Control was best maintained in increments, and today’s delay was one of them.
The phone buzzed on the nightstand, and without looking, he swiped to answer.
“Hey,” he muttered.
“Why do you sound like someone kicked your cat?” Seungmin’s voice was sharp and alert even through the speaker.
Felix exhaled hard. “The owner just messaged me. Apparently, there’s gonna be delays about the… building shit—whatever construction nonsense they’re doing. She doesn’t even understand it herself to explain thoroughly, but I need that unit by next weekend. I told her that already.”
There was a beat of silence on the other end before Seungmin spoke again, voice dripping with casual sarcasm. “Then just live with your teacher. What’s the problem?”
Felix sat up halfway, his tone defensive. “That’s not it—”
“Yes, it is. You literally started the whole fire to make him panic and fuck you. And wow, now you live there getting dicked down. Mission more than accomplished.”
Felix groaned and rolled his eyes. “That’s not it, Seungmin. I just… I just need my place back. I can't have my plan get messed up because of that delay.”
"Felix... Your professor is your fifth guinea pig, experimental shit you log in your book. And you have like more than forty body counts at the age of twenty fucking one."
"And what about it? I'm not like you. You stopped dating after that one high school breakup." He yawned as if the statistics of people he slept with was normal and didn't bother him. Seungmin sounded hesitant to speak for quite sometime. Then slowly spoke, making sure he won't offend his best friend. "This is the first time you're losing control..."
"Oh Seungmin, you're worrying too much like I didn't stalk this man for years and—" He stopped talking when the faint click of the front door echoed from the living room. His voice dropped. “I’ll call you back.”
Without waiting for a reply, he ended the call and tossed the phone aside. He stretched out on the bed, staring at the ceiling for a moment before aimlessly grabbing his phone again and scrolling through Instagram. The mindless flick of his thumb against the screen was oddly calming. Faces, outfits, coffee cups, and sunset shots blurring past in quick succession.
The sound of footsteps grew louder down the hallway, and a moment later, the door opened. Hyunjin stepped inside without knocking, carrying something large tucked under his arm. Felix’s eyes flicked up, registering the sight of a massive dark brown teddy bear before glancing back down at his phone.
Without preamble, Hyunjin dropped the bear onto the bed beside him. The soft thud made Felix look up in confusion.
“Uh? Sir, what’s this for?”
“To complete your innocent look, Felix. Thought you’d need the accessory,” Hyunjin scoffed, his tone dripping with ridicule, lips curling into a derisive smirk. He leaned back against the doorframe, “I bought healthy takeouts and a bingsu. Come outside for dinner.”
Felix let his gaze linger on the bear for a moment before rolling his eyes dramatically. “The hell is this,” he muttered, setting the plush aside.
Hyunjin didn’t wait for him to move. He simply gave that look. The one that was both a challenge and a dare and left the door open as he stepped back toward the hallway.
Felix lay there a few moments longer, the faint smell of whatever “healthy” food Hyunjin had brought drifting in from the kitchen. It was annoyingly tempting, and that, more than anything else, got him up from the bed. Plus the bingsu he absentmindedly craving.
