Summary
"Jinu didn't care if their blood was black or red - as long as it was pooling beneath them. As long as the patterns on his body went deeper, as long as the pain in his chest stayed a constant, almost a pleasure. He killed them anyway."
Or: In a world where people stay the same age until they fall in love with their soulmate, Jinu is someone who has been killing his for the last 400 years to stay immortal. Rumi is the most recent reincarnation of his soulmate. Killing her, however, is not as easy as he had expected it to be.

Summary
"Did Jinu expect to get a (kind of panicked) message at midnight the night before? Absolutely not.
He received zero explanation on what was going on and why it was urgent. He hated not knowing what the problem was.
So he found himself by the river half an hour before he was supposed to be there."
or: Rumi tells Jinu what she overheard at the restaurant and he decides to risk his sanity out of pure curiousity (or so he tells himself)

Summary
And, at first, the woman herself had almost rejected her companion’s offer (or should she say demand), if not for the fact that it was the perfect place to have a conversation without the wrong people overhearing – loud, crowded, people all perfectly distracted by their own voices. And, as large as Seoul was, there were quite a lot of wrong people who could overhear.
or: celine and jinu's mom try to have a private conversation about their little problem without prying ears but they pick the wrong restaurant for this

That One Mess We Call Life 1.0 by BrainlessIndividualWithTooMuchFreeTime
Fandom KPop Demon Hunters (2025)
05 Jan 2026
Summary
Real life doesn't have demons or hunters, or weapons. But it's still messy. It has this horrifying thing called human emotions.
Rumi is a Musical Engineering student by day and a waitress by night. Jinu has very bad luck, until he doesn't. Zoey and Mystery work at a flower shop. Mira only loves her two friends and dance, or so she thought. Romance is called delusional 24/7, but isn't he just optimistic? Abby might look dumb, but is probably the only one who can deal with his lovesick friends. And Baby is a full time wingman, no matter if he wants it or not. Or if he's good at it or not.
None of them expected to become each other's everything. And yet, day by day, they find themselves calling each other family.
In which there are no demons, but there is a shit ton of feelings, everyone is falling in love, the past bleeds into the present and Jinu's mom somehow ended up with seven extra kids. And one very nosy bus driver ended up adopting eight twenty year olds.
A human AU, consisting of a bunch of one shots, connected into something resembling a plot, mostly fluff, a bit of angst and hopefully somewhere between the bad writing, we all learn something about that one mess we call life.

Summary
Celine went missing when Rumi was 15. Her grandmother, the director of security at Honmoon inc. persuaded her to give up the luxury house, and start working for the company early. Rumi hopes to make it into the idol stream so she can be a company pop-star, but she just has to work night shift guarding the old archives for a few months.
Then one day a complete dingus shows up. He's the first real demon she's ever met - and he ruins everything!
Rumi's life, all her preconceived ideas about demons and how she feels about the company that raised her are turned upside-down.
A dystopian AU. The girls and Jinu will defeat the powers of late-stage capitalism and fascism though the power of love, friendship and awesome songs.

Summary
Rumi hates port towns.
The breeze is wet; stray hairs cling to the nape of her neck, slick with sweat. The smell of salt and fish permeate all over, leaving her to crinkle her nose.
Rumi is a shaman. Jinu is a sorcerer from the deepest depths of the sea. They shouldn't have any reason to meet.

Summary
“You know,” Rumi pulls away from the holographic lock with a huff, “When they offered me a ‘Highly advanced artificial intelligence’ to implant into a chip in my head and assured me how ‘Helpful’ you’d be and how much easier my tasks would become in the process, they really failed to mention how chatty and needy you could be.”
A pleasant little buzz ripples through her head. Rumi has quickly learned that’s his version of a laugh.
“Have you considered I just have a lot of helpful things to say?”
“I would love to hear what makes half the things you say ‘Helpful’ in your eyes.” Rumi snarks back. She doesn’t need a physical projection to know he’s smirking at her now.
“Do you want help or not? You haven’t actually answered me.”
(Or Rumi is an agent and infiltrator, top in her field. Jinu is a highly advanced artificial intelligence, recently implanted in her head to aid her in missions for the past three weeks. Though, Rumi can’t help but feel like he’s more than just a computer program…)

Summary
When the first song died out and transitioned into the next Rumi spoke up, “Do you know how to dance?” She asked him with a glint in her eyes.
“Course I do. I just prefer not to feel like a sardine in a tin can. Dense crowds really aren’t my thing.” He answered carefully.
“Alright then, let’s dance, just the two of us, out here alone. Whatcha say?” She challenged.
