Chapter 6: Scent and Sensibility
The weeks after the movie night had passed in a blur of routine and unspoken understanding. The secret, once a jagged shard of glass Katsuki carried in his gut, had been polished smooth by Izuku’s quiet solidarity. It was still heavy. It still had edges that could cut. But it no longer felt like it was bleeding him dry from the inside.
This new equilibrium, however, created its own peculiar pressure. Every family dinner where Shouta’s deep voice rumbled about responsibility, about an alpha’s duty to provide and protect a future omega mate, felt like a slow twist of a tourniquet. Every time Hizashi, with his cheerful, traditional expectations, would ask Katsuki with a twinkle in his eye if any nice omegas had caught his attention at school, the weight in Katsuki’s chest would swell.
He watched his father. Really watched him. Shouta Aizawa was a monolith of tradition, yes. His beliefs were the steel girders of their family’s structure. But he was also the man who, after a brutal case at the firm, would sit in his study not with whiskey, but with a cup of Hizashi’s chamomile tea, staring at a framed photo of their mating ceremony. He was the alpha who, when Izuku had presented as omega at thirteen, had not celebrated with boasts of a future advantageous mating, but had simply knelt before his weeping son, wiped his tears with a calloused thumb, and said, “You are perfect as you are.” The memory was a beacon in Katsuki’s turmoil.
It was that memory, more than anything, that finally pushed him to the edge of speech.
The opportunity presented itself on a Tuesday evening. Hizashi was at a community choir rehearsal, his melodic laughter absent from the halls. Izuku was in his room, a soft symphony of humming and the click of knitting needles drifting under his door; he was working on a new sweater, a complex cable pattern he’d been obsessed with for days.
The living room was a pool of quiet amber light. Katsuki sat on the low, sleek sofa, his posture uncharacterically rigid. He wasn’t sprawled. He was coiled, elbows on his knees, his large hands clasped tightly together. The television was on, some muted news report about economic forecasts, its flickering blue light doing nothing to illuminate the tension in the room.
Shouta sat in his customary armchair across from the sofa, a book on legal precedents open in his lap. He wore reading glasses, which softened the severe lines of his face. The scent of sandalwood and old paper clung to him, a familiar, paternal anchor. He’d glanced at Katsuki once when he’d come in, noted the tense line of his son’s shoulders, and had simply returned to his book, offering the space for Katsuki to speak.
The silence stretched, thick and syrupy. The hum of the refrigerator from the kitchen seemed deafening. Katsuki’s own scent, usually a confident crackle of ozone, was tinged with something sour—anxiety, sharp and electric.
He cleared his throat. The sound was like gravel tearing.
Shouta slowly closed his book, placing a leather bookmark between the pages with deliberate care. He set it on the side table, removed his glasses, and folded them. His black eyes, now unfiltered, settled on Katsuki. He didn’t speak. He simply waited, his presence an immovable object in the quiet room.
Katsuki’s mouth was desert-dry. He tried to summon the arrogance that was his armor, the casual flippancy he used as a shield. It crumbled to dust before it could reach his tongue. All that was left was the raw, terrifying truth.
“Dad.” The word came out rough.
Shouta inclined his head, a silent prompt.
Katsuki looked down at his own hands, at the scuffed knuckles from yesterday’s workout, at the faint scar on his thumb from a childhood accident. He couldn’t look at his father’s face. Not yet.
“So.” He sucked in a breath that felt like shards. “I’ve been… seeing someone. For a few weeks. Maybe months now.”
The admission hung in the air. Shouta didn’t move. The news anchor droned on about interest rates.
“Okay,” Shouta said finally, his voice a low, measured rumble. There was no judgment in it. Not yet. Just factual acknowledgment. “And who is this someone? An omega, I’d presume.”
It was the expected question. The natural question in their world. It was the question that carved a canyon of fear right through Katsuki’s center.
His breath hitched, a ragged, involuntary sound. He clenched his fists so tight his tendons ached. The sour scent of his distress spiked, cutting through the sandalwood. He forced his head up. His crimson eyes, wide and desperately young, met his father’s obsidian gaze.
“It’s…” The name was a stone in his throat. He swallowed, hard. “It’s… Eijirou.”
For a moment, there was nothing. No reaction. Shouta’s face was a mask of carved granite, utterly still. The only movement was the slight, almost imperceptible flare of his nostrils as he processed the scent of his son’s terror, and the name that had caused it.
Then, the mask fractured. Not in a dramatic way. There was no shout, no slam of a fist. It was the subtle draining of understanding from his eyes, replaced by a slow, dawning incredulity. His brows drew together by a fraction of a millimeter. His lips, usually set in a firm line, parted slightly.
“Eijirou,” Shouta repeated. The name was neutral, but the context made it a seismic event. “Kirishima’s boy.”
Katsuki could only nod, a sharp, jerky motion.
“Eijirou is an alpha,” Shouta said. It wasn’t a question. It was a statement of immutable fact, like saying the sky was above them. He said it slowly, as if testing the weight and fit of each syllable in the reality of his living room.
“I know.” Katsuki’s voice was a whisper.
The silence that followed was a physical thing. It pressed down on Katsuki’s shoulders, squeezed his lungs. He saw the calculations flicker behind his father’s eyes—the societal rules, the traditional pathways, the expectations he himself embodied and enforced. The disappointment. The shame. The violation of a natural order Shouta had built his life, and his family, upon.
Katsuki braced for it. For the cold dismissal. For the hardened gaze. For the lecture that would fracture their relationship forever. He was ready to become a problem to be solved, a deviance to be corrected. He stared at the polished wooden floor between his feet, waiting for the world to end.
The soft rustle of fabric made him flinch.
He looked up.
Shouta was leaning forward in his chair, his powerful forearms resting on his knees. His expression was not one of anger, but of deep, profound confusion. The stern alpha, the pillar of tradition, looked… lost.
“Katsuki,” he began, his voice hushed, as if they might be overheard by the very walls. “Explain this to me. Help me understand.”
It wasn’t rejection. It was a request. It was a lifeline.
The dam inside Katsuki broke. The words tumbled out, clumsy and desperate. “I didn’t plan it. I swear. It just… happened. We’d work out, and then we’d talk. And he… he doesn’t treat me like a competition. He doesn’t treat me like I’m just… an alpha. He sees me. He makes me laugh. He’s strong, and he’s kind, and he’s so… so damn good, Dad. And I…” His voice cracked. He looked away, shame heating his face. “I feel like myself with him. More than I ever have with anyone else.”
He risked a glance. Shouta was listening, his head tilted, his gaze fixed on a point somewhere on the rug. He was absorbing the words, turning them over.
“The… the physical part,” Shouta said, the words careful, clinical. “It is… mutual?”
Katsuki’s face burned. “Yes. It’s… it’s not about dominance. It’s not about… winning. It’s just… it’s different. It’s equal.”
Shouta absorbed this, his jaw working slightly. He exhaled, a long, slow breath that seemed to deflate him. He leaned back in his chair, looking not at Katsuki, but up at the ceiling, as if searching the plain white plaster for answers.
“You know what the world says,” Shouta stated, his voice flat. “You know what our community believes. An alpha’s purpose is to bond with an omega, to create a family, to provide a stable, traditional home. It is the foundation of everything.” He lowered his gaze, and now his black eyes pinned Katsuki. “It is what I believe.”
The words were a death knell. Katsuki’s heart plummeted.
“I know,” he repeated, the fight gone from him. He felt hollowed out, exhausted. “I’m sorry.”
“Don’t,” Shouta said sharply, and Katsuki flinched again. “Do not apologize for what you feel. I did not ask for an apology.”
The contradiction stunned Katsuki into silence.
Shouta ran a hand over his face, the weary gesture of a man grappling with a paradox. “What I believe… and what I see sitting before me… they are not aligning, Katsuki. I believe in the natural order. I believe in tradition. They have given me a life, a family, a purpose I cherish.” He paused, his eyes drifting to the hallway that led to the bedrooms, to where Hizashi’s scent was strongest. “But I also believe the evidence before my own eyes. I see my son. My strong, proud, brilliant son. And I see that you are terrified to tell me this. I see that this… connection… has given you a kind of peace, even as it torments you.”
He stood up suddenly. Katsuki recoiled, his body tensing for a blow, verbal or otherwise.
Shouta didn’t advance. He simply stood there, a towering figure in the lamplight, his shadow long and dark across the floor. He turned and walked to the large window that looked out onto their meticulously kept garden. He clasped his hands behind his back.
“When your mother presented as omega,” Shouta said, his voice distant, “his family had already arranged a mating with the son of a prominent banking family. A ‘suitable’ alpha. Traditional. Respectable.” He was silent for a moment. “Hizashi refused. He said the alpha’s scent made his skin crawl. He said he would rather live a solitary life than be bonded to a statue of propriety. His family was furious. They called him foolish. They said he was throwing away security, status.”
Katsuki had never heard this story. He sat, frozen, listening.
“I was the unsuitable one,” Shouta continued, a faint, wry ghost of a smile touching his profile. “A second son, studying law but with no family connections to speak of. My only offering was… myself. It was not the recommended path.” He turned from the window, his gaze landing on Katsuki with a new, piercing intensity. “Tradition is a guide, Katsuki. It is a map drawn by those who came before. But it is not the territory. The territory is messy. It is human. It is your mother’s courage to choose his own comfort over convention. It is… it is the scent of my son’s fear in my own living room because he loves in a way the map does not acknowledge.”
He walked back, stopping before the sofa. He loomed over Katsuki, not with threat, but with a palpable, overwhelming presence.
“Eijirou,” Shouta said, testing the name again. “He is a good young man. He has a strong character. He respects this house. He looks at you…” Shouta trailed off, searching for the right observation. “He looks at you as if you hold the answer to a question he has been asking. I have seen it. I simply did not understand what I was seeing.”
Katsuki could not breathe. He could only stare up at his father, his vision beginning to blur at the edges.
“This path you are on,” Shouta said, his voice dropping to a gravelly murmur. “It will be difficult. It will be, in many ways, harder than any path I could have imagined for you. There will be those who will not understand. There will be ugliness. You cannot hide forever. Secrets like this… they gain weight over time. They become unsustainable.”
“I know,” Katsuki whispered, a tear finally breaking free and tracing a hot path down his cheek. He hated it, swiped at it angrily.
“If this is real,” Shouta said, and now he knelt. He lowered his large, powerful frame until he was on one knee before the sofa, putting his eyes level with Katsuki’s. The gesture was one of such profound humility, such intentional lowering of alpha dominance, that it stole the air from the room. “If this is a true bond, and not a rebellion or a passing confusion… then you will need armor. You will need a fortress. The world will not give it to you.”
He reached out. His hands, so large they could engulf Katsuki’s, came to rest on his son’s shoulders. The grip was firm, grounding, unshakeable.
“So you will have mine.”
The words were simple. Absolute.
The dam inside Katsuki shattered completely. A choked, broken sound escaped him, and the tears came in earnest, not of fear or shame, but of a relief so vast it was terrifying. He crumpled forward, his forehead coming to rest against his father’s broad shoulder. The sandalwood and paper scent enveloped him, the smell of safety, of home.
Shouta’s arms closed around him. They were not the gentle, perfumed embrace of Hizashi. They were an alpha’s embrace—all hard muscle and unyielding strength, a bulwark against a hostile world. One hand cupped the back of Katsuki’s head, fingers tangling in the spiky blond hair, holding him secure.
“You are my son,” Shouta murmured into his hair, his own voice thick with an emotion he rarely voiced. “My firstborn. My boy. That is the only tradition that matters to me right now. You and Izuku. That is my purpose.”
Katsuki wept. He wept for the months of fear, for the weight he had carried alone, for the unexpected, staggering gift of being seen and not cast out. He clung to his father’s shirt, his body shaking with the force of his silent sobs.
Shouta held him. He didn’t offer platitudes. He didn’t shush him. He simply absorbed the storm, his own grip tightening periodically, a silent communication of steadfastness.
When the tremors finally began to subside, and Katsuki’s breathing evened into ragged hiccups, Shouta slowly released him. He stayed kneeling, his hands now on Katsuki’s shoulders again, looking him directly in the face. Katsuki’s eyes were red-rimmed, his face blotchy, utterly stripped bare.
“We will navigate this,” Shouta said, his tone returning to its practical, planning cadence. “Your mother… he will need time. His heart is traditional, but it is soft. He loves you. That will win out, but it may be… loud.” A flicker of something akin to dread passed over Shouta’s features. “We will tell him together, when the time is right. Not tonight.”
Katsuki nodded, numb.
“And Izuku?” Shouta asked.
“He knows,” Katsuki croaked. “He… figured it out. Weeks ago.”
A genuine look of surprise crossed Shouta’s face, followed swiftly by a deep, paternal pride. “Of course he did. That boy sees everything.” He shook his head slightly, a real smile finally touching his lips. “He has known?”
“For a while,” Katsuki croaked, wiping his face with the back of his hand. “He… he hugged me too.”
Shouta’s smile deepened, a rare and beautiful thing. “Then you have been richer than you knew. You have had a brother’s loyalty. Now you have a father’s.” He stood, his knees cracking faintly, and offered a hand to pull Katsuki up. “Your mother… we will tell him together. In time. He will need to process it differently. His world is more… socially intricate. But he loves you. That will be his compass, as it is mine.”
Katsuki stood on unsteady legs, feeling both lighter than air and more solidly rooted to the earth than ever before.
“For now,” Shouta said, clapping a heavy hand on his shoulder, “this stays within these walls. You, me, Izuku. We will determine the next steps carefully. You will not be reckless. You will not force a public confrontation before you are both ready. Understood?”
“Yes, Dad.”
“Good.” Shouta picked up his book from the side table, a gesture of normalcy that felt profoundly significant. He looked at his son, his gaze encompassing all of him—the strength, the vulnerability, the tear-stained cheeks. “Now, go wash your face. You look like you’ve been through a war.”
As Katsuki turned to leave the room, heading for the sanctuary of the hallway bathroom, Shouta’s voice stopped him one last time.
“Katsuki.”
He turned.
His father was still holding the book, his expression unreadable. “Invite Eijirou for dinner on Friday. Not as your secret. As our guest. Let me… let me see what I am supporting.”
It wasn’t approval. Not fully. It was an assessment. An engagement. It was a first, crucial step on an uncharted map.
A fresh wave of emotion, sweeter and cleaner than the last, hit Katsuki. He couldn’t speak. He just nodded, a sharp, decisive dip of his chin.
He walked down the hall, the polished wood cool under his bare feet. As he passed Izuku’s door, it was open a crack. The soft clicking of needles had stopped. In the dim light of his brother’s lamp, Katsuki saw a single, large black eye peering out. It crinkled at the corner. Then, a small, pale hand emerged, gave a quick, wiggling wave of solidarity, and disappeared, the knitting resuming its gentle, rhythmic sound.
Katsuki leaned against the wall outside the bathroom, letting out a long, shuddering breath that seemed to come from the soles of his feet. The house around him was the same. The amber light, the scent of incense and lemon polish, the murmur of the television. But the atmosphere had shifted. The silence no longer felt like a verdict waiting to be passed.
It felt, for the first time in months, like peace.
