The Domestic Life Of Shinsou And Kaminari.

The Hum of the Afterglow

The alarm clock on the nightstand was a cruel reminder that the rest of the world didn't stop just because Hitoshi and Denki had found a perfect, static-charged equilibrium in their bed. It buzzed with a persistent, tinny vibration that cut through the heavy silence of the bedroom.

Hitoshi groaned, the sound muffled by the pillow. He felt like his limbs were made of lead, weighted down by a delicious, post-coital lethargy that made the idea of putting on a hero costume feel like a Herculean task. Beside him, Denki didn't even stir; the blonde was a sprawling disaster of limbs, his face smashed into the mattress, one leg hooked over Hitoshi’s hip as if to anchor him there permanently.

"Denki," Hitoshi rasped, his voice sounding like it had been dragged over gravel. "The alarm."

A muffled grunt was the only response. Denki’s hand blindly wandered across the sheets, searching for the source of the noise before eventually finding Hitoshi’s face and patting it clumsily.

"Kill it," Denki mumbled into the fabric. "Murder the clock, 'Toshi. Use your Quirk on it. Make it stop."

"That’s not how my Quirk works and you know it," Hitoshi sighed, reaching out to slap the snooze button. The silence that followed was heavy and sweet. He slumped back down, feeling the residual warmth of Denki’s skin against his own.

Despite the looming meeting at the agency, Hitoshi found himself lingering. He turned on his side, watching the rhythmic rise and fall of Denki’s shoulders. The scars on Denki’s back—faint, jagged lines from a stray piece of shrapnel during a raid two years ago—caught the light. Hitoshi traced them with a feather-light touch, his fingers ghosting over the skin.

Denki shivered, a small spark of yellow light dancing between his shoulder blades. He rolled over, blinking up at Hitoshi with eyes that were still hazy and soft. "You’re staring," Denki whispered, a sleepy, lopsided smirk tugging at the corners of his mouth.

"I’m observing," Hitoshi corrected. "There’s a difference."

"Yeah, yeah. Pro-hero 'Mind Jack' is just doing surveillance on his husband. Totally professional." Denki reached up, rubbing the sleep from his eyes before tangling his fingers in the messy violet locks of Hitoshi’s hair. "You have that look in your eyes again. The one where you’re wondering if this is a dream."

Hitoshi didn't deny it. He leaned down, pressing his forehead against Denki’s. "It’s a persistent worry. You’re very loud for a dream, though."

"I’m the loudest," Denki agreed, pulling Hitoshi down for a slow, deep kiss that tasted like the lingering heat of the morning. It wasn't urgent like the passion from an hour ago; it was grounded, a promise made in the quiet safety of their four walls.

When they finally broke apart, Denki’s eyes were a little brighter, the gold in them shimmering with affection. "We should probably get up. If we’re late to the agency again, Fat Gum is going to give me that 'disappointed dad' look, and I can't handle it. It hurts my soul."

"And Eraserhead will just stare at me until I wish I were invisible," Hitoshi added, finally sitting up and swinging his legs over the side of the bed. The cool air of the room hit his bare skin, making him miss Denki’s heat instantly.

The process of getting ready was a choreographed dance they had perfected over the last year of living together. While Hitoshi managed to actually make the coffee this time without being tackled, Denki scavenged through the laundry basket for his favorite pair of socks—the ones with the tiny lightning bolts on them.

Hitoshi stood by the kitchen island, sipping his black coffee and watching Denki struggle to pull on his hero leggings. The blonde was hopping on one foot, his tongue poking out of the corner of his mouth in concentration.

"You know, for a man who can move at the speed of light when he wants to, you’re remarkably uncoordinated," Hitoshi remarked dryly.

Denki stopped, wobbling precariously before falling back onto the sofa with a huff. "Gravity is my natural enemy, Hitoshi! It’s a constant battle. Besides, I’m distracted."

"By what?"

Denki looked up, his expression softening as he took in the sight of Hitoshi. Shinsou was wearing his tactical black turtle neck, the high collar framing his sharp jawline. His capture scarf was draped over a chair nearby, looking like a sleeping serpent. "By you. You look really good in your gear, you know? It’s unfair. I look like a human battery and you look like a mysterious noir protagonist."

Hitoshi felt a faint heat creep up his neck. He looked away, focusing on the bottom of his mug. "It’s functional. Black hides the dirt and the blood."

"And it makes your eyes pop," Denki added, jumping up and sliding the rest of his gear on with renewed energy. He crossed the kitchen in three quick strides, sliding his arms around Hitoshi’s neck and leaning into his space. "I’m serious. Sometimes I look at you out there, leading the perimeter or taking down a villain with just a word, and I think... damn. That’s mine. I get to go home with that guy."

Hitoshi set the mug down, his hands finding Denki’s waist. The bravado he usually wore like armor felt thin in the face of Denki’s earnestness. "I think the same thing when you're clearing a path for the civilians. You’re the light everyone looks for, Denki. I’m just the shadow that follows you."

Denki frowned, his nose wrinkling. "Don't do that. Don't do the 'shadow' thing. Shadows can't exist without light, sure, but light is just blinding and chaotic without something to give it shape. You give me shape, 'Toshi."

He leaned in, kissing Hitoshi’s cheek, then his nose, then his lips. "Now, let’s go be heroes so we can come back and order that overpriced Thai food you like."

The walk to the agency was brisk. They walked close enough that their shoulders occasionally brushed, a silent communication between them. On the streets, they were professional—heads up, eyes scanning the crowds—but the way Denki’s pinky finger occasionally hooked into Hitoshi’s was a secret they kept for themselves.

The meeting at the agency was as tedious as expected. They sat in a glass-walled conference room with several other pro-heroes, reviewing patrol routes and recent sightings of a minor smuggling ring. Hitoshi sat with his arms crossed, his expression unreadable and cold, the picture of the stoic, calculating hero.

Across the table, Denki was vibrating with restless energy, clicking a pen repeatedly until Bakugou, who was sitting two seats down, threatened to blow his hand off.

Hitoshi caught Denki’s eye. He didn't say a word, didn't even move a muscle, but the subtle shift in his gaze was enough. *Stop it,* the look said. *You’re annoying the explosive one.*

Denki offered a sheepish grin and put the pen down, instead opting to draw little lightning bolts on the corner of his notepad.

As the meeting wrapped up, Fat Gum clapped a large hand on Denki’s shoulder. "Good energy today, Chargebolt! Glad to see you’re well-rested. You and Mind Jack have the East District tonight, right?"

"You bet!" Denki chirped, his smile bright enough to rival the overhead fluorescent lights. "We’ll have the place locked down before sunset."

"Try not to destroy any more streetlights this time, Kaminari," Eraserhead’s voice drifted over from the doorway. Shota Aizawa looked as tired as ever, his yellow sleeping bag tucked under one arm like a security blanket. He leveled a steady look at Hitoshi. "And you. Keep him on a leash. I don't want to fill out more property damage reports."

"I’ll do my best, Sensei," Hitoshi replied, his voice devoid of its usual sarcasm.

Once they were out in the hallway, heading toward the lockers to grab the rest of their equipment, Denki let out a long, dramatic exhale. "Man, Aizawa-sensei still scares me. It’s been years! Why does he still look at me like I’m about to eat a tide pod?"

"Because you once tried to see if you could charge a phone with your tongue," Hitoshi reminded him.

"That was for science!"

"That was for a dare from Kirishima, and you ended up with a numb face for three hours."

They laughed, the sound echoing in the sterile hallway. It was these moments—the shared history, the inside jokes—that made the weight of their jobs feel lighter.

The patrol itself was relatively quiet. The East District was mostly residential, filled with families and small shops. They walked the perimeter, Denki waving at kids who recognized him and Hitoshi keeping a sharp eye on the alleyways.

As the sun began to set, painting the sky in bruises of purple and orange, they found themselves on a rooftop overlooking a small park. The air was cooling down, and the first stars were beginning to peek through the city’s light pollution.

"Peaceful," Denki said, sitting on the edge of the roof, his legs dangling over the side. He patted the spot next to him.

Hitoshi sat down, his capture scarf loosening slightly around his neck. "Too peaceful. It makes me nervous."

"Relax, 'Toshi. Even villains need a night off. Maybe they’re all at home watching Netflix too." Denki leaned back on his elbows, looking up at the sky. "It’s nice, isn't it? Just... being."

Hitoshi looked at him. The sunset light was hitting Denki’s hair, making the blonde strands look like spun gold. There was a smudge of dirt on his cheek from earlier when he’d helped a shopkeeper move some crates, and his eyes were clear and calm.

"Yeah," Hitoshi said softly. "It is."

He reached out, taking Denki’s hand. Their fingers interlaced naturally, a perfect fit. In the silence of the evening, Hitoshi could feel the faint, rhythmic hum of Denki’s Quirk—a steady, low-level vibration that felt like a heartbeat. It was a comforting sensation, one that reminded him he wasn't alone in the dark.

"I was thinking," Denki started, his voice uncharacteristically quiet. "About what you said this morning. About me making the world quiet enough to breathe."

Hitoshi stiffened slightly, his inner cynic wanting to retreat, but he forced himself to stay present. "What about it?"

"I think it’s the opposite for me," Denki said, turning his head to look at Hitoshi. "The world is always so loud for me. My brain is always buzzing, and there’s always so much input, so much... static. But when I’m with you, it’s like someone finally tuned the radio to the right station. Everything becomes clear. I don't feel like I’m drowning in the noise anymore."

Hitoshi felt a lump form in his throat. He squeezed Denki’s hand, his thumb tracing the knuckles. "I didn't know you felt like that."

"I’m not great at the deep stuff, I know," Denki chuckled, though there was a slight wobble to it. "I usually just make a joke or act like an idiot because it’s easier than explaining that I’m constantly terrified of short-circuiting my own life. But with you... I don't have to be the 'Chargebolt' that everyone expects. I can just be Denki."

Hitoshi pulled Denki closer, wrapping an arm around his shoulders. "You’re more than enough as just Denki. I thought I made that clear this morning."

Denki leaned his head on Hitoshi’s shoulder, closing his eyes. "You did. I just wanted to say it back. You’re my grounding wire, Hitoshi. Literally and figuratively."

They stayed there for a long time, watching the city lights flicker on below them like a sea of fallen stars. The responsibility of being heroes was heavy, a burden they carried every day, but in moments like this, it felt manageable. They were two halves of a whole, a balance of shadow and light, silence and sound.

"Hey, 'Toshi?"

"Mmm?"

"Can we still get the Thai food? I’m starving. I think I burned like three thousand calories just thinking today."

Hitoshi let out a soft laugh, the sound carrying on the night breeze. "Yes, Denki. We can get the Thai food."

"With the extra spicy noodles?"

"If you promise not to complain about your mouth being on fire for the rest of the night."

"I make no such promises!"

They stood up, brushing the dust off their costumes. As they prepared to leap down from the roof and finish their patrol, Denki paused, looking at Hitoshi with a mischievous glint in his eye.

"Race you to the station? Loser pays for the spring rolls."

Before Hitoshi could even respond, Denki was gone, a streak of yellow light and a crackle of ozone disappearing over the edge of the building.

"Cheater!" Hitoshi yelled, but he was already moving, his capture scarf shooting out to snag a nearby flagpole as he swung himself into the air.

He was smiling as he chased the light. The world was loud, and the work was never finished, but as long as he had that golden-haired disaster to come home to, Hitoshi Shinsou knew he could handle anything.

They reached the end of the block at almost the same time, breathless and laughing, their hearts beating in sync. As they walked the final stretch toward the agency to clock out, the static of the world faded into the background, replaced by the simple, beautiful reality of being together.

The apartment was waiting for them—warm, quiet, and filled with the scent of lavender and coffee. It was their sanctuary, the place where the masks came off and the heroes became just two men in love. And as the door clicked shut behind them later that night, Hitoshi knew that no matter how dark the world got, he would always have a reason to find his way back to the light.
