Chapter 1: Forbidden Desires
The living room held the day’s quiet warmth, a pool of amber light cast by the late afternoon sun sliding through the shoji screens. The scent of polished cypress and the faint, ever-present sandalwood from the family altar mixed with the green, damp smell of freshly watered soil. Hizashi moved with a silent, practiced grace between large ceramic pots, his long fingers checking leaves, his slender form a brushstroke of calm against the serene backdrop. The soft shush-shush of water from his small brass can was the room’s steady heartbeat.
On the deep red tatami, near the low kotatsu table, Shouta’s presence was an anchor. He sat with his laptop open, the blue-white glow a stark contrast to the warm tones of the room. His black hair fell loosely around his stern face, his broad shoulders set in a line of concentration. The crisp, clean notes of his alpha scent—oakmoss and sharp black tea—defined his space, a scent of unspoken authority. He wasn’t typing, though. His dark eyes, lifted from the screen, were fixed on his children.
Izuku lay on his stomach, a plush mauve cushion tucked under his chest, his feet idly kicking the air behind him. The magazine spread before him was glossy and bright, filled with images of alphas in various states of dress—athletic wear, sharp suits, casual denim. His wavy black hair formed a curtain around his face, which was flushed with a fascinated, private intensity. His own scent, a soft melody of green tea and honeysuckle, sweetened the air around him.
Katsuki was sprawled beside him, one muscular arm braced behind Izuku’s back, his crimson eyes scanning the pages with a critical, almost proprietary glare. He smelled of salt, clean sweat, and the faint, warm cinnamon of his dynamic, an alpha scent that was youthfully potent. He wore a tight black tank top, his post-workout physique still humming with visible energy.
“See this guy?” Katsuki jabbed a finger at a photo of a alpha posing on a mountain peak, muscles corded. “Lat spread is decent, I’ll give him that. But his core looks weak. Bet he skips leg day. His scent’s probably all over the place—pine, but cheap, like air freshener.”
Izuku giggled, a soft, breathy sound. “You can’t tell his scent from a picture, Kacchan.”
“The hell I can’t. Look at his eyes. No focus. Scent control is part of presentation.” Katsuki flipped the page with a dismissive flick. “This one’s better. Shoulders are balanced. Good definition here.” He traced a line along the model’s abdominal v-cut. “Probably smells like iron and cedar. Solid.”
Izuku’s own large black eyes grew dreamy. He pointed a shy finger at a different image, an alpha with a kinder smile, holding a puppy. “He looks… gentle.”
Katsuki snorted. “Gentle is for betas. You need strong. Gentle is in how he treats you, not how he looks. That guy?” He leaned closer, his voice dropping to a conspiratorial growl that vibrated in Izuku’s space. “He’s posing. The pup’s probably sedated. His smile doesn’t reach his eyes. His scent would be all wrong up close—fake sweet, like candy hiding something sour.”
A small, wistful sigh escaped Izuku. He rolled onto his side, facing his brother, his waist-length hair fanning out. “How will I know, though? When I meet him. My alpha. How will I know he’s… perfect?”
Katsuki’s gaze softened, just a fraction, the harsh lines of his face easing. “Your nose will know first. Your gut will know second. He’ll smell like safety and want, all mixed together. And he’ll look at you like you’re the only damn thing in the room.” He poked Izuku’s forehead. “And he’ll be built like he can actually protect you. Not one of these paperweights.”
From his place by a drooping fiddle-leaf fig, Hizashi smiled, the expression a quiet sunbeam. He caught Shouta’s eye across the room. A silent communication passed between them, a thread of profound satisfaction. Hearing their omega son articulate his domestic dreams, and their alpha son articulate his protective standards—it was the melody their lives were composed to.
“He should be tall,” Izuku whispered, as if sharing a profound secret. “Taller than me, obviously. And his hands… I want them to be big. So you can see the strength in them, even when he’s being careful.”
“Good,” Katsuki grunted, approving. “You’re getting it. Size matters. Not just for show. For practicality. For when he has to lift something for you, or pull you close.” He shifted, the tatami creaking under his weight. “You’re gonna carry his pups, Izuku. He better be fuckin’ perfect. His genes, his discipline, his scent… everything. You don’t settle for less. You hear me? Not even a little.”
The words, raw and fiercely protective, hung in the air. Izuku’s blush deepened, spreading down his neck. The idea of pups, of a swollen belly and a quiet nursery, filled his chest with a fluttering, warm ache. He nodded, solemn. “I won’t, Kacchan.”
Shouta finally closed his laptop lid with a soft, deliberate click. The sound drew the room’s focus to him. “Katsuki is correct,” he stated, his voice a low rumble that settled in the bones. “The selection of a mate is the most critical duty an omega has. It shapes generations. Instinct is your guide, Izuku, but it must be tempered with discernment. The flashiest alpha is often the weakest in character.”
He stood, unfolding his height, his shadow stretching across the room. He walked over and placed a heavy, warm hand on Izuku’s head, ruffling his hair. The touch was firm, loving in its absolute certainty. “Your mother’s discernment is what brought our family its harmony. You have his eyes for what truly matters.”
Hizashi set down his watering can, gliding over to join the circle. He knelt beside Izuku, the fabric of his cream-colored kimono whisper-soft. His scent of jasmine and milk enveloped them, a balm. “It’s also about the day after the thrill, sweetheart,” he said, his voice like honey steeped in quiet strength. “It’s about who brings you tea without asking when you’re weary. Who knows when to speak and when to simply fill the silence. Your daddy…” He glanced up at Shouta, green eyes shining with decades of understood devotion. “He never let me carry a single grocery bag. Not once, in all our years. That is perfection. It’s in the quiet things.”
Izuku absorbed this, looking from his mama’s serene face to his daddy’s stern, approving one. The magazine’s glamorous images seemed to fade, replaced by a quieter, more profound picture: his father’s large hand on his mother’s lower back as they walked, the way his mama always had Shouta’s favorite ceramic cup ready just as he arrived home. That was the blueprint.
Katsuki watched his parents, a contemplative look sharpening his features. He saw the dynamic not as theory, but as living history. The way his father’s dominance wasn’t a bullying force, but a sheltering one. The way his mother’s submission wasn’t weakness, but a powerful, graceful flow that directed the very current of their home. He wanted that. No, he would build that.
“Gonna hit the gym,” Katsuki announced suddenly, pushing himself up in one fluid, powerful motion. “S’crowded later. Want to get my sets in.”
“Dinner at seven,” Hizashi reminded him gently, reaching up to smooth a stray, spiky hair at Katsuki’s temple. He allowed it for a second, a faint, almost imperceptible lean into the touch.
“I know, Mama.” Katsuki shrugged on a hoodie, the fabric straining across his back. He looked down at Izuku, who was still curled on the floor. “Keep that list in your head, `Zuku. Tall, strong, good hands. Smells like home. And he better make you laugh. If he’s boring, he’s out.”
Izuku nodded, hugging the cushion to his chest. “Have a good workout, Kacchan.”
With a final, confident nod to his father, Katsuki left, his energetic scent and palpable presence fading from the room, leaving a sudden, softer quiet in his wake.
The three of them remained, suspended in the golden light. Shouta resumed his seat, opening his laptop once more, but the set of his shoulders was softer. Hizashi began gathering the discarded teacups from earlier.
Izuku stared at the magazine cover, not really seeing it anymore. He was seeing strong hands carefully holding an infant. Hearing a deep laugh in a sun-drenched kitchen. Smelling a scent that was uniquely, comfortingly alpha, woven into the fabric of a future home. His heart, a tender, hopeful thing, beat a steady rhythm against the tatami mat.
Perfection wasn’t a photograph. It was a promise, built day by day. And for the first time, the path to it didn’t just feel like a dream. It felt, listening to the rustle of his mama’s kimono and the steady click of his daddy’s keyboard, like an inevitable, beautiful inheritance.
