Chapter Text
The law firm of Siri & Associates was a world built on sharp edges. It was all cold marble, freezing air conditioning, and the suffocating weight of billion-dollar contracts. Ryu spent his days navigating it with a perfectly knotted tie and an armor of absolute indifference.
But his home was a different kind of battlefield entirely.
Ryu loosened his tie as he pushed open the front door, the heavy click of the lock signaling the end of his workday. He expected the usual afternoon chaos, nearly 14-year-old Riran complaining about homework, 22-year-old old Ray raiding the fridge, and a strict, elderly scholar drilling 9-year-old Rrin on her maths exercise. Instead, the house was draped in the thick, quiet heat of the late afternoon. The golden hour sun was pouring through the hallway windows like spilled honey, leading Ryu toward the half open door of the study.
He didn't announce himself. He just stopped in the doorway, his exhaustion evaporating in a single heartbeat. Because the man sitting on the floor with his little sister wasn't an elderly scholar. He looked like he had been spun from moonlight. He was dressed simply, slacks and a crisp button-down shirt. But there was an effortless, magnetic grace to him. The two of them were surrounded by scattered crayons and geometry papers. Rrin was deeply focused on drawing a butterfly, humming quietly to herself.
Thinking he was entirely alone with the child, the tutor allowed himself a moment of laziness.
Ryu watched, rooted to the spot, as the man let out a soft, exhausted sigh and tilted his head back. Elegant fingers reached up to his own collar, lazily unfastening the top two buttons. He dragged a hand down his exposed, sweat dampened neck to rub at his pulse point. It was an innocent gesture meant to cool off, but the slow, languid way he moved was inherently, devastatingly provocative. The golden light caught the curve of his throat, and Ryu felt a sudden, heavy shift in his own chest.
The lawyer who was paid to have an answer for everything suddenly found his brain completely re-wiring itself. A slow, dangerous, and thoroughly amused smile spread across Ryu's face.
'Pretty' a quiet, terrifyingly certain voice echoed in his head. Ryu leaned casually against the wooden doorframe and didn't bother to clear his throat politely. Instead, he let his deep, velvet smooth voice fill the quiet room. "If I knew Rrin’s tutor was going to make unbuttoning a shirt look like an art form, I would have skipped my afternoon meetings."
The tutor snapped his head toward the door so fast he nearly dropped his charcoal pencil. His dark, wide eyes clashed with Ryu’s. Pat expected to see a stern, disapproving guardian. Instead, he found a man with broad shoulders and a ruthlessly tailored suit, looking down at him with dark, hungry eyes. Ryu didn't look away. He held the tutor's gaze with the practiced ease of a hunter, his smile deepening as he let his eyes drop deliberately to the exposed skin of the younger man's neck.
In a fraction of a second, the tutor's confident, laid back aura completely shattered. A violent, beautiful flush crept up from his unbuttoned collar, painting his neck and face a brilliant crimson. His elegant fingers suddenly turned clumsy, fumbling wildly as he tried to re-button his shirt, accidentally smudging black charcoal all over his own collar in his panic.
"I— I was just—" he stammered, his voice a soft, breathless rasp that did absolutely nothing to help Ryu's self-control.
"Take your time," Ryu drawled lazily, crossing his arms over his chest. He took one slow, deliberate step into the room. "I’m enjoying the view." Pat’s breath hitched. He opened his mouth to reply, but his brain had completely short circuited.
Before Pat could embarrass himself further, the soft pad of footsteps echoed down the hallway. Riran wandered into the doorway, casually sipping from a peach juice box. She stopped dead in her tracks, blinking at the tall figure in the tailored suit.
"P' Ryu?" Riran lowered the juice box, her eyebrows shooting up into her hairline. "Why are you home before the moon is out? Did the firm finally fire you?"
It was a valid question. As the eldest son of the state’s most prominent real estate tycoons, Ryu could have easily coasted into a corner office at his parents' firm. Instead, he had chosen to build his own name in the brutal, exhausting world of litigation. He usually worked up to seventy hour weeks, surviving on black coffee and sheer, stubborn drive. Seeing him home at 5:00 PM on a Tuesday was like spotting a ghost.
But Ryu didn't answer her. He didn't even look at her. His dark, captivated gaze remained entirely fixed on the flustered tutor on the floor. Riran followed her brother's gaze. She looked at the smudged charcoal on Pat’s collar, the violently red flush creeping up his neck, and the predatory, highly amused smirk resting on Ryu’s handsome face.
She took a slow sip of her juice. "Careful, Teacher Pat," she deadpans, her voice dry as the desert. "Your face is matching the red crayon. And P' Ryu, why are you looking at him like I'm not here? You look like you're about to eat him."
"Riran," Ryu warned softly, though the deep rumble of a chuckle vibrated in his chest. At the sound of his name, youngest Rrin finally looked up from her butterfly drawing. Her face broke into a massive, missing-tooth grin. "P' Ryu! You're home!"
"I am," Ryu said, finally breaking his gaze away from Pat to look at his little sister.
He stepped fully into the sunlit study, the fluid grace of his movements demanding the entire room's attention. Ryu wasn't bulky or aggressively muscular. He was built like the hero of a high end cinema film, incredibly tall, lean, and sharp in all the right places. The expensive fabric of his suit draped perfectly over broad shoulders, highlighting a physique that was elegant, powerful, and utterly refined. He crouched down gracefully to Rrin's level, heedless of the dust on the carpet ruining his designer slacks. He ruffled her hair with a large, warm hand. "And who is this?"
"This is Teacher Pat!" Rrin announced proudly. "He’s teaching me how butterfly wings are exactly the same on both sides. It's called symmetry."
"Is that right?" Ryu murmured. He shifted his weight, turning to face Pat directly. Up close, the devastating strike of Ryu’s sharp jawline and piercing dark eyes was almost too much for Pat to handle.
"Nice to meet you, Teacher Pat," Ryu said, his voice dripping with honey and unmistakable intent. He extended a long, elegant hand. "I'm Ryu. Rrin’s older brother." Pat wiped his charcoal stained fingers hurriedly on his slacks, his heart hammering wildly against his ribs. He had always been casually confident. He knew he was good looking, and he usually had a playful, slightly naughty charm that made people gravitate toward him. But sitting under the quiet, heavy intensity of Ryu’s gaze, all of Pat's practiced charm evaporated. He felt entirely exposed.
Shyly, Pat reached out and placed his hand in Ryu’s.
The moment their skin touched, a jolt of electricity shot up Pat’s arm. Ryu’s grip was warm and certain, his long fingers wrapping around Pat’s as though he had all the time in the world. Pat suddenly, acutely aware of his own. His fingers curled instinctively, a little too stiff, a little too careful, like he wasn’t sure what to do with the contact. It wasn't a normal handshake. It was a promise.
"I... it's a pleasure, Khun Ryu," Pat managed to stammer, hating how breathless he sounded. "I didn't expect you... I was told the parents—"
"My parents are usually out of the country for their real estate firm," Ryu interrupted smoothly, his thumb doing one more agonizingly slow swipe over Pat's knuckles before he finally, reluctantly, let go. "I'm the one who handles the household. So, you'll be dealing directly with me."
Ryu stood back up, towering over Pat once more. He slipped one hand casually into his pocket, his suit jacket falling perfectly back into place.
"Riran is right. I usually work very late," Ryu said, his eyes dropping briefly to the open collar of Pat's shirt before coming back up to catch Pat's terrified, mesmerized gaze. A slow, devastatingly handsome smile spread across his face. "But seeing how well my little sister is being taken care of... I think I'm going to start coming home early a lot more often."
Riran let out a loud, exaggerated groan from the doorway. "Oh, gross. I'm going to my room." Pat just sat there on the carpet, completely paralyzed, his face burning brighter than the evening sun.
He had taken this job because he needed it. Because survival, lately, had been measured in small, practical decisions. Steady income. Manageable hours. A nine-year-old and a stack of math worksheets.
Simple. Safe. But as he looked up at the man standing before him. Sharp, composed, and watching him just a second too long, something in that careful equation began to falter.
Teaching math to a nine-year-old was going to be easy.
Surviving her older brother, however…was beginning to feel less like a challenge and more like the start of a very dangerous kind of story. And he wonders if he will survive.
