All the Lights Stay On

Summary:

In an alternate universe where demons don’t exist, Jinu and Rumi are just world-famous K-pop idols trying to balance stardom with marriage and raising their four-year-old twins.

Between chaotic breakfasts, glitter cereal, and visits from fellow Huntrix and Saja Boys members, they find time to fall in love all over again.

A soft, domestic one-shot about idols, family, and the kind of love that lasts after the stage lights fade.

Notes:

Hey everyone. I’ve been obsessing over this movie since it dropped and needed to write a fic about my girls and boys.

However like stated, this is an alternate universe, so there is no demons and they’re normal idols.

I’ve also changed the names of the Saja Boys excluding Jinu.

Mystery = Minho
Romance = Rinwoo
Baby = Bomi
Abby = Aejin

(See the end of the work for more notes.)

Work Text:

~~~

When the world knew you as one of the world’s most legendary power couple, privacy became a precious, slippery thing.

Jinu had learned this the hard way: signing autographs in grocery aisles, whispering “I love you” in parking garages, hiding behind ridiculous bucket hats when all he wanted was iced coffee and five uninterrupted minutes with his wife.

But right now?

Right now, in a sun-drenched living room where toys cluttered every surface and twin four-year-olds were tearing through the house wearing capes made from branded concert towels?

Right now, Jinu had everything he needed.

“Appa, Minji put glitter in my cereal again!”

Jinho’s tiny feet padded urgently into the kitchen, carrying a bowl of milk-logged cornflakes and a smattering of silver sparkles.

From the dining table, Rumi didn’t even look up from her phone. “It’s fiber. Let him eat it.”

“Eomma!” Jinho wailed.

“I’m kidding,” she said, reaching over to wipe his cheek with a napkin. “Minji, come apologize to your brother.”

The four year old girl poked her head around the corner, eyes gleaming with mischief. “But he said he wanted a magical breakfast!”

“She’s not wrong,” Jinu muttered, sipping his coffee. “Looks like he’s about to summon a glitter dragon.”

“Appaaaa.”

“Alright, alright,” he said, standing. “Let’s go rinse that bowl and make some normal food.”

Minji climbed into Rumi’s lap while Jinho reluctantly followed Jinu to the sink. As Jinu washed out the cereal, Jinho clung to his side, eyes still suspicious. “Can glitter go in your tummy?”

“If it’s the edible kind,” his father said. “But this isn’t. So maybe no more spells before breakfast, okay?”

Jinho sighed, far too dramatic for a child his size. “Being a twin is hard.”

Jinu tousled his hair with an amused expression.

———

By mid-morning, Rumi was sprawled across the living room floor, tangled in coloring books and two overly talkative children. Her phone buzzed beside her, lighting up with group chat messages from Huntrix’s shared thread. Mira had sent seventeen voice notes about choreography, Zoey had dropped a cryptic teaser about new outfits, and their manager had just added a “very casual” rehearsal to the calendar.

The purple-headed woman groaned.

“Trouble in idol paradise?” Jinu called from the hallway, buttoning his shirt with one hand while carrying a laundry basket with the other.

“Mira wants to change the chorus choreo. Again.” Rumi looked down at her twins, both now trying to draw faces on her knees. “You know, before kids, I had time to rehearse for eighteen hours straight.”

“You still rehearse for eighteen hours straight,” her husband said, walking in. “You just do it while microwaving fish sticks, bathing 4 year olds and wiping glue off the furniture.”

She smiled, tired but grateful. “We’re the busiest washed-up idols in the world.”

“Speak for yourself,” he said, striking a ridiculous pose. “Saja Boys are still the blueprint of boy bands.”

“Saja Boys have been on hiatus for four months.”

“Strategic hiatus.”

“Strategic naptime,” she corrected, reaching to poke his stomach.

He caught her hand, bringing it to his lips. “You still love me, though.”

“I married you, didn’t I?”

Their daughter looked up. “Can you two just kiss already?”

Jinho groaned. “Again?”

Jinu grinned and leaned in, planting a dramatic, smooching kiss on his wife’s lips.

Their twins screamed. “Ewwwwww!”

⸻

That afternoon, the house filled with noise again…this time, with friends.

Minho and Zoey arrived first, their two-year-old daughter clinging to her mother’s leg like a baby koala.

“Sorry we’re late,” Zoey huffed, swinging the diaper bag over her shoulder. “Minah had opinions about which shoes she wanted to wear.”

“She wanted none,” Minho added, grinning. “I respect that.”

Rumi stepped aside to let them in, smiling as Minah immediately bolted across the room to Minji and Jinho. “Our living room has become a daycare once again.”

“A stylish daycare,” Minho corrected. “With vintage posters and designer baby mats.”

“Don’t judge the mat,” Jinu called from the kitchen. “It was a gift from Bomi and Aejin. Imported from France.”

Right on cue, the two appeared at the door, arms full of snacks.

“Imported cheese puffs from France,” Aejin said with a wink. “Because the gays have taste.”

Bomi bowed dramatically. “And expensive impulse control.”

Rinwoo and Mira arrived last, Rinwoo in a crisp linen shirt and Mira in designer sunglasses, both looking like they’d just stepped off a photoshoot.

“Your driveway is chaos,” Rinwoo commented.

“We like to keep things humble,” Jinu said. “Come in before the glitter storm returns.”

⸻

By late afternoon, the house was full of soft music, open windows, and the smell of takeout. The kids had migrated to the backyard, supervised in rotating shifts by the adult idols pretending they weren’t international superstars.

In the kitchen, Zoey sat at the island with Rumi, eating mandu with one hand while bouncing Minah on her lap.

“Do you ever miss it?” she asked.

“The tours?”

Zoey nodded. “The freedom. The airport rush. Fans crying in the front row.”

Rumi thought about it, then smiled. “Sometimes. But then Jinho throws up on my sweater or Minji tries to paint the dog, and I realize… this is a different kind of stage. A perfect one.”

Zoey looked up, touched. “That’s poetic.”

“Shut up,” Rumi said, tossing a napkin at her.

⸻

Outside, Jinu was crouched by the sandbox, showing Jinho how to build a fortress while Minji narrated their kingdom’s tragic backstory to a very confused Minah.

“So then the Evil Queen tried to steal our glitter cereal—”

“Why does she want it?” Minah whispered, eyes wide.

“Because it gives you sparkle powers, obviously.”

Behind them, Bomi snapped a photo.

Aejin wrapped an arm around his waist from behind and leaned over his shoulder. “You’re posting that, right?”

“Already tagged you. #UnclesOfTheYear.”

Inside, Mira appeared behind Rumi, brushing sand off her skirt. “Your kids are going to rule the world one day.”

“Let’s just get through preschool first.”

Mira slid into a chair beside her. “Remember when we were teens, practicing in that tiny dorm room?”

“You mean when Zoey used to cry on the bathroom floor at 2 a.m. and claim she’d never survive debut?”

“Hey!” Zoey yelled from the sink. “Those were valid tears!”

They all laughed.

⸻

As dusk fell, the guests trickled out: hugging goodbye with lingering smiles, promises to do it again next week, as if coordinating eight idol schedules and three children wasn’t a miracle.

By 8:30, the house was quiet again. The twins were bathed and in bed, tangled in a pile of storybooks and stuffed animals. Jinu leaned in to kiss their foreheads, Rumi right behind him.

“Goodnight, my stars,” she whispered.

Minji mumbled something about glitter.

Jinho rolled over and muttered, “No cereal dragons, please.”

Their mother smiled. “No promises.”

⸻

Back downstairs, they collapsed onto the couch. No lights but the warm flicker of the standing lamp, soft music still playing in the background.

Rumi leaned her head on Jinu’s shoulder. “You know what I realized today?”

“Hm?”

“We haven’t had a moment alone in two weeks.”

He slid his hand into hers. “Technically, right now counts.”

“Does it count if there’s yogurt in my hair?”

He laughed. “It always counts with you.”

They sat like that for a while: quiet and content.

“I want to write again,” she said suddenly. “New music. Real music. Not just commercial stuff.”

“You should,” he said without hesitation. “Your voice deserves the world.”

She tilted her head up to look at him. “Would you… write with me?”

He smiled. “Always.”

Then he kissed her. Gently, like a promise. Like the chorus to a song only they knew.

Somewhere in Seoul, on a fan forum:

[User: foreverhuntrix]
Did anyone else see the blurry photo someone posted of Jinu and Rumi at a park with their kids??

[User: sajaboysluvr]
THEY LOOK SO HAPPY I’M CRYING 😭😭😭
Saja Boys x Huntrix forever!

[User: queertigerbomi]
Also did y’all see Bomi and Aejin’s Insta story? The backyard picnic??? Jinu was building a glitter castle. A GLITTER CASTLE.

[User: maknaesrule]
They’re literally idols raising idols. Minji and Minah are going to lead a girl group by the time they’re six.

[User: romcomrumi]
Honestly? Power couple. Endgame. Love is real.

⸻

Jinu traced soft circles on Rumi’s hand with his thumb.

“I’ve been thinking,” he said.

She hummed sleepily.

“We should write a song for the twins. Like, really write it. Not a jingle. Something they can listen to when they’re older. When we’re old and embarrassing.”

Rumi turned to look at him, eyes shining.

“Something that says…” He trailed off, searching.

She filled it in. “That even when the lights go out on the stage, they stay on at home.”

He nodded.

She kissed his cheek. “Let’s call it Encore.”

He grinned. “Too on the nose.”

“You love it.”

“I love you”

And in the silence that followed, with their fingers still laced and the world finally quiet, they started to hum a melody together: soft, unpolished, full of love.

A lullaby, a promise, a beginning.

Their encore.

Notes:

Author’s Note: I hope you enjoyed this short one-shot. I really loved writing it…and it warmed my heart after that tragic ending of Jinu….I’m definitely still in denial :(

 

Please comment if you want maybe a next one-shot or maybe a series of one-shots with the different couples. Let me know~

Until then…

With Love,
