The Domestic Life Of Shinsou And Kaminari.

Whiskers, Wires, and Watermelon Soda

The morning sunlight was particularly persistent, stabbing through a gap in the blackout curtains like a golden needle. Hitoshi Shinsou groaned, burying his face in the crook of Denki’s neck to escape the intrusion. Usually, this was the part of the day where they’d discuss the grim realities of patrol shifts or the latest villain sightings, but today was different. Today was a sanctioned "Normal Human Day." No costumes, no capture scarves, and absolutely no quirk-usage unless someone was literally about to die.

"Stop vibrating," Hitoshi mumbled against Denki’s skin. "It’s too early for you to be this caffeinated."

"I’m not caffeinated, I’m excited!" Denki chirped, his voice already at a level ten. He was currently bouncing his leg under the duvet, a habit that made the entire mattress feel like a massage chair on its highest setting. "We have the list, 'Toshi! The 'Fun Couple Activities' list that Mina and Uraraka made for us. We’ve been living like old retired men. It’s time for adventure!"

Hitoshi pulled back just enough to look at Denki. The blonde was already wide-awake, his golden hair standing up in even more directions than usual, looking like a dandelion that had survived a thunderstorm. "Adventure? Denki, the first item on that list is a cat cafe. That’s just my Tuesday, but with more expensive tea."

"But it’s a *themed* cat cafe," Denki insisted, sitting up and dragging Hitoshi with him by the hands. "And after that, we’re going to that international grocery store that sells the weird sodas. You know, the ones that look like they belong in a laboratory? Come on, get up! The cats won't pet themselves!"

Hitoshi sighed, though the small, fond tug at the corner of his mouth betrayed him. He allowed himself to be hauled out of bed, his long limbs feeling heavy but his heart strangely light. Living with Denki was like living inside a lightning storm—chaotic, occasionally blinding, but never, ever dull.

An hour later, they were walking down a busy street in the Shizuoka Prefecture, dressed in civilian clothes that made them look like any other young couple. Hitoshi wore a simple black hoodie and jeans, while Denki had opted for a bright yellow windbreaker that made him look like a very fashionable safety cone.

The "Neko-Neko Sanctuary" was tucked away in a quiet alley, marked by a neon sign of a cat winking. As they stepped inside, the chime of a bell was immediately drowned out by Denki’s high-pitched gasp.

"Oh my god, 'Toshi, look at the one with the tiny hat!"

Hitoshi scanned the room. It was filled with soft cushions, climbing towers, and approximately fifteen felines of various breeds. In the corner, a very round ginger tabby was indeed wearing a tiny, crocheted wizard hat.

"It’s a gimmick, Denki," Hitoshi said, even as he instinctively reached out to scratch a passing calico behind the ears. The cat let out a loud, rumbling purr, and Hitoshi felt his shoulders drop two inches.

"You say gimmick, I say magical," Denki countered, already sitting cross-legged on the floor. Within seconds, he was covered. A sleek black cat had claimed his lap, while a fluffy white one was batting at the zipper of his jacket. "Look! I’m a conduit for fluff! I’m the King of Cats!"

Hitoshi sat down on a velvet sofa nearby, watching Denki interact with the animals. It was one of his favorite sights—the way Denki’s restless energy softened when he was around something small and innocent. There was no pressure here to be a hero, no expectation to be the "Chargebolt" who could level a city block. He was just a boy with a heart too big for his chest, letting a tabby knead his stomach.

"You should get a picture," Denki whispered, afraid to move and disturb his new subjects. "Send it to Aizawa-sensei. Show him I’ve finally mastered crowd control."

"He’d probably just tell you that you’re distracting the cats from their naps," Hitoshi replied, though he did pull out his phone and snap a photo. In the frame, Denki was beaming, his eyes crinkling at the corners, looking more radiant than any hero billboard.

They spent two hours there, sipping lukewarm matcha and letting the cats dictate their movements. For Hitoshi, who spent most of his life analyzing people’s intentions and guarding his own mind, the simplicity of the animals was a balm. They didn't care about his Quirk. They didn't care if he looked tired or cold. They just wanted the warmth of his hand.

"Okay, next stop!" Denki announced as they finally disentangled themselves from the feline kingdom. "The 'Global Sip and Snack.' I saw a TikTok about it. They have soda that tastes like curry and chips that taste like blue cheese and honey."

"That sounds like a direct attack on my digestive system," Hitoshi said, but he followed anyway, his hand finding Denki’s in the crowded street.

The store was a sensory overload. Rows upon rows of brightly colored packages from across the globe lined the shelves. Denki was like a kid in a candy store—literally. He grabbed a basket and began throwing things in with reckless abandon.

"Watermelon soda from Spain! Wasabi chocolate from... somewhere! Oh, look, 'Toshi! This one says it’s 'Electric Grape.' It’s me in a bottle!"

Hitoshi picked up a glass bottle filled with a translucent blue liquid. "This one is labeled 'Deep Sea Mystery.' I’m fairly certain this is just window cleaner with sugar in it."

"Only one way to find out!" Denki chirped, tossing it into the basket.

By the time they reached the checkout, they had a haul that would make a nutritionist weep. They carried their treasures back to the apartment, the sun beginning to dip toward the horizon, casting long, purple shadows over the city.

Back in their kitchen, they lined up the beverages like a row of colorful soldiers.

"Okay, the rules are simple," Denki said, grabbing two glasses. "We try everything. No spitting it out unless it’s actually poisonous."

"I feel like I should have my medical insurance card on the counter for this," Hitosling muttered, but he picked up the 'Deep Sea Mystery' first.

They spent the next hour laughing and gagging in equal measure. The watermelon soda was a hit, but the curry-flavored drink resulted in Denki running to the sink to rinse his mouth out while Hitoshi doubled over in rare, wheezing laughter.

"That... that was a crime," Denki wheezed, leaning against the counter. "Who hurt the person who invented that? Why would you do that to a liquid?"

"It’s a bold choice," Hitoshi managed to say, wiping a tear from his eye. "Very experimental."

"You’re mocking me," Denki pouted, though his eyes were dancing. He stepped closer, the playful energy in the room shifting as it always did when they were alone. The humor was still there, but it was being overtaken by that familiar, magnetic pull. "I think I need a palate cleanser. Something that doesn't taste like turmeric."

He reached out, his hands sliding over Hitoshi’s shoulders, pulling him in. Hitoshi didn't resist. He liked the way Denki smelled after a day like this—like sunshine, cat fur, and that ridiculous strawberry lip balm he insisted on wearing.

"I have a better idea than soda," Hitoshi whispered, his voice dropping into that low, gravelly register that made Denki’s knees weak.

He leaned down, capturing Denki’s lips in a kiss that started sweet and quickly deepened into something more urgent. It tasted like the sugar from the soda and the warmth of the afternoon. Denki let out a soft, needy hum, his hands tangling in the back of Hitoshi’s hair, pulling him closer until there was no air left between them.

"The list," Denki breathed against his mouth. "We... we didn't finish the list. There was a 'sunset walk' on there."

"The sun is already down, Denki," Hitoshi murmured, his hands sliding down to grip Denki’s hips, hoisting him up onto the kitchen counter. "And I’ve had enough walking for one day."

Denki wrapped his legs around Hitoshi’s waist, his head tilting back as Hitoshi’s mouth moved to his neck. Small, involuntary sparks began to dance across Denki’s skin, a physical manifestation of his rising heat. "Hitoshi... you’re cheating. You’re using the 'Mind Jack' voice."

"I’m not using my Quirk," Hitoshi replied, his teeth nipping at the sensitive cord of Denki’s throat. "This is just me. Do you want me to stop?"

"Don't you dare," Denki gasped, his fingers digging into Hitoshi’s shoulders.

They moved from the kitchen to the bedroom in a blur of heated skin and discarded clothing. The "Normal Human Day" was over, replaced by the raw, electric reality of their private world. When they hit the sheets, it wasn't about being heroes or symbols; it was about the friction of skin, the rhythm of breath, and the absolute trust they held in each other’s hands.

Hitoshi was patient, his movements deliberate as he worshiped every inch of Denki’s body. He loved the way Denki reacted to him—the way his back arched, the way his eyes blew wide and gold, the way he breathed Hitoshi’s name like a prayer.

"Look at me, Denki," Hitoshi whispered, his thumbs tracing the lightning-bolt scars on Denki’s forearms.

Denki opened his eyes, his gaze hazy with pleasure but fixed entirely on Hitoshi. "Always. I’m always looking at you."

As they moved together, the air in the room grew heavy with the scent of ozone. Denki’s Quirk flared instinctively, tiny blue and yellow sparks jumping between their bodies, a harmless but exhilarating static that made every touch feel a thousand times more intense. It was like being inside a star, a private universe where the only law was the connection between them.

When the climax finally hit, it was a total system override. Denki’s body went rigid, a bright flash of light illuminating the room for a split second as he released a small, joyous burst of energy. Hitoshi collapsed against him, his heart racing in tandem with the fading sparks.

Minutes later, they lay tangled together, the only sound the distant hum of the city and the steady rhythm of their breathing. Denki’s head was tucked under Hitoshi’s chin, his skin still warm and slightly damp.

"I think..." Denki started, his voice a sleepy murmur. "I think the 'Couple Activities' list was a success."

Hitoshi chuckled, his fingers tracing patterns on Denki’s back. "The cats were good. The soda was a disaster. The ending... the ending was the best part."

"Yeah," Denki agreed, snuggling closer. "Hey, 'Toshi? What’s on the list for tomorrow?"

Hitoshi reached over to the nightstand, picking up the crumpled piece of paper Mina had given them. He scanned the messy handwriting. "Tomorrow says... 'Group Karaoke with Class A.'"

Denki groaned, burying his face in Hitoshi’s chest. "Okay, new plan. Tomorrow we’re 'missing in action.' We’re staying right here. We can finish the 'Deep Sea Mystery' soda and watch that documentary about the giant squids."

"I think that’s the first sensible thing you’ve said all day," Hitoshi said, kissing the top of Denki’s head.

He reached over and clicked off the lamp, plunging the room into a soft, comfortable darkness. In the quiet, Hitoshi felt a profound sense of gratitude. He had spent so much of his life waiting for the other shoe to drop, waiting for the world to tell him he didn't belong. But here, with Denki, he didn't have to wait anymore. He was home.

"Goodnight, my human battery," Hitoshi whispered.

"Goodnight, tired cat dad," Denki replied, already half-asleep.

As the moon climbed higher, casting a silver glow over the quiet apartment, the two heroes slept. They had fought monsters, survived wars, and carried the weight of a society on their shoulders. But tonight, they were just two people, grounded by love and the lingering scent of watermelon soda, ready to face whatever the morning—and the rest of the list—had in store for them.
