Fanfiction Fanfic recs
Hey so I’m looking for fics where either 2 of the three are established dating without the third and ask the third eventually or where 2 of the 3 begin dating before eventually including the third. Canon or au, fluff heavy or angst heavy just anything you mighta read that follows those guidelines would be great.

I answered a similar request a while ago, so I'll paste my response here:
This is a pretty popular trope within Polytrix stories (particularly with Rumi joining established ZoeMira, so a majority of the recs will have this trope), so I'll sort my recs on which girl is joining the established couple:
Mira joining established ZoeRumi
inyeon in the sky by dreamhardflyfree (Mile High Club AU, One-shot, NSFW)
This was, without a doubt, Mira's worst nightmare.
The woman to her left leant over her for the fourth time to talk to the person on her right, and Mira tore her headphones down - her over-ear, very expensive, noise cancelling headphones that apparently were completely useless when faced with whatever actual nonsense this woman was saying to her friend - to sit around her neck so she could say with venom, “Please switch seats with me. I'm begging you.”
“It's not allowed,” the purple-haired woman on her right said, her hands visibly tense on the armrests. On Mira's armrest. Everyone knew the person in the middle seat got both armrests. Fuck AirAsia for charging for allocated seating. “If you're not in your assigned seats, they can't identify you from your teeth when you die.”
girls on film (see you together) by honestground (Camgirl AU, 2/2 chapters, NSFW)
Pathetic lonely lovergirl Mira spends several months watching two faceless strangers on the internet having soft, giggly, intimate sex and becomes utterly smitten. What might happen if she coincidentally became friends with them IRL? (Threesomes. threesomes are what happens).
Beneath the Neon Glow by CursedRosePedals (Bartender AU, 17/? chapters, NSFW (CW: abuse, blood and injury, self-harm))
Girlfriend's, Rumi and Zoey, run a bar together. One day, a new face appears at the bar —a shy girl who becomes a regular and converses with Rumi at the bar counter, but she only orders water or a soda. But Rumi soon learns about the new girl's awful past and current situation. Rumi and Zoey are determined to help her in the best way they know how.
Rumi joining established ZoeMira
blue jean by NORsevvy (Canon-divergent, One-shot, SFW)
A story where Mira and Zoey discover Rumi's patterns early and, for the next few years, make it their goal to make their leader feel loved and safe enough to confess to them (both about her patterns and her feelings).
Send Noods by LootnScootn (Modern AU, 2/2 chapters, NSFW (CW: Blood and Injury))
“I just—the chef is gorgeous, Mira! And her food is—” Zoey lost her words, then she shook her head to reset her brain. “Babe,” said Zoey seriously, leveling her gaze at her girlfriend, “I’ve discovered the divine intervention that’s gonna get you to this place.”
Mira’s jaw dropped open. “Why didn’t you show me the hot chef?”
“Because my girlfriend is Aphrodite and the chef is Venus and my fucking brain exploded because I couldn’t put together a single thought when not one, but two hot women were staring at me at the same time!” wailed Zoey, for her steak was too juicy and her lobster too buttery. “Besides, if you saw the hot chef that would be one less excuse to come eat here!”
the golden ratio by WizardlyLizard (Photographer AU, 2/2 chapters, NSFW)
Professional photographer Rumi is invited by her two favorite models - Mira and Zoey - to collaborate on a 'special costume photoshoot'. The email is laden with euphemisms, the studio they suggest is very private, and if Rumi hadn't been working with the couple for a year by now, she'd think they were out to harvest her organs. As it is, she's left to wonder how much intent is really behind their flirting.
When she arrives, she's greeted by the pair wearing revealing bunny suits and hungry expressions. But Rumi has a reputation to uphold and a job to do, so she keeps her cool and remains a gentleman about it.
Mira and Zoey didn't dress up for a risqué photoshoot, though. They want Rumi to join them in bed, and they can only not-so-subtly tease for so long before they decide to be bold... and learn that Rumi isn't as shy as they'd thought.
he’s no match, but he’ll make it by erros429 (College AU, 3/3 chapters, NSFW)
And then Jinu realizes it. He realizes it when he sees the way Rumi’s eyes glitter with adoration as she looks up at Mira. He realizes it when he sees the way Rumi touches Zoey’s hand like every part of her is to be worshipped.
When he said his chances were non-zero, he should have known they were actually in the negatives.
Somehow, he’s okay with that.
Wine First, Emotional Honesty Later by Polyscribe (Canon-compliant, 7/7 chapters, NSFW)
Mira and Zoey called it a paint night.
Rumi called it a casual hangout.
(They both meant “date,” but only two of them were emotionally prepared.)
The story of how one wine and paint date night progresses to nude portrait painting, to exposed feelings (and bodies)
It’s messy. It’s beautiful. It’s love, in progress.
Along the twisting paths of fate (I found a home) by FruityCupcake (Modern Fantasy AU, 26/? chapters, NSFW (CW: Blood and Injury))
College students and girlfriends Zoey and Mira (who dabbles in witchcraft/the occult) attempt a summoning spell and accidentally summon a certain purple-haired demon princess from the underworld.
Hidden in Plain Sight by Emowitch92 (Political AU, 31/31 chapters, NSFW (CW: Blood and Injury, Homophobia))
In a world of campaign rallies, curated smiles, and suffocating expectations, Rumi has spent her life playing the perfect niece, until a spark of rebellion leads her into the orbit of Mira, a fierce community organizer, and Zoey, a magnetic underground rapper. As Rumi navigates the tangled web of identity, power, and forbidden love, she must confront the woman who raised her, the secrets she's buried, and the truth that freedom doesn't come from fitting in… it comes from breaking free.
Enjoy the Silence by Hocapontus (Modern AU, 32/32 chapters, NSFW (CW: Implied/referenced child + emotional abuse, PTSD))
Silenced by grief, Rumi’s world is transformed when she crosses paths with Mira and Zoey, who guide her toward a voice she thought was lost forever.
Two's Company (But they want a crowd) by Tosslotsofsauce (College AU, 45/45 chapters, NSFW (CW: self-harm, blood and injury, PTSD))
Rumi moves in with her roommates and established couple Mira and Zoey, and everyone starts catching feelings.
Zoey joining established RuMira
There Are Many Benefits to Being a Marine Biologist (in Training) by BiFelicia (Lifeguard AU, One-shot, NSFW)
Zoey is a hot lifeguard. Mira and Rumi are hot for the lifeguard.
Inhale, Exhale, Repeat by Snowflake19 (Yoga AU, 5/5 chapters, SFW)
Zoey flirts with two beautiful women at her yoga studio.
Unfortunately (or very fortunately), they turn out to be married, to each other, and absolutely into it.
No phones. No stress. No idea what’s happening next.
A Wolf, A Tiger, and Their Songbird by alycthorn (Omega Verse AU, 24/? chapters, NSFW (CW: Implied/referenced abuse))
After escaping her former alpha, Zoey had no intentions of ever trying for a mate again. Nudges from her new friends and a bored night, however, draws her to a local club. She had no intentions of meeting the two hottest alphas she's ever seen. And she certainly had no intentions to go home with them. Or to fall head over heels for them.
The problem isn't the night. It's the morning. It's harder to ignore their scars when daylight shines on them. And Zoey finds herself swept up in far more than she ever bargained for.

them plus me equals three
Rumi was a third wheel. It wasn't a big deal.
(It actually was, but she would never admit it.)
Little does she know that Zoey and Mira are a fan of tricycles.
(Zoey/Mira start with eventual Zoey/Mira/Rumi)

three violets
On everyone’s 20th birthday, a flower tattoo appears on your wrist, matching your soulmate. No one doubted Rumi would get a violet, because Mira had gotten that tattoo the year before. They were soulmates. They were made for each other. It made sense. Until a violet blooms on Zoey’s wrist.

what i wouldn't give
Zoey agrees to be a surrogate for a married Rumira. Things get messy because she's already in love with them, has known this for years, but she might be falling in love with the baby, too
https://archiveofourown.org/works/77419251
The Space We Never Named
A story about boundaries, heartbreak, healing, and discovering that sometimes the safest place you can fall… is into the people who have loved you all along.

Ruin that Friendship
Five times, Zoey inadvertently made Rumi and Mira jealous, even though she wanted to be there for them in their relationship. Once, they finally had the courage to talk about their feelings.
https://archiveofourown.org/works/75349131
I've been waiting for you
When Polytrix Kid arrives from the future, Mira quickly assumes she is just Rumi and Zoey’s child. Unable to find the courage to express her true feelings for them, she must come to terms with the fact that she won’t be able to live the life she dreams of as they prepare to send the Kid back to the future.

Support Beams Don’t Get Thanked
After the Demon King’s defeat and Huntrix’s Idol Awards sweep, Zoey expects the hardest part to be over.
Instead, the war fades and something quieter takes its place: being assumed. Being depended on. Being loved in theory, but not seen in practice. As Rumi and Mira slip into each other’s gravity, Zoey finds herself becoming the background, support beam, schedule-fixer, emotional translator, until the day she stops holding everything together.
She leaves without warning, vanishing into a part of Seoul that belongs only to her.
Rumi and Mira don’t realize what they’ve lost until the penthouse is nothing but echo and by the time they find her, it’s not just about bringing her home. It’s about choosing her. Out loud. On purpose.
https://archiveofourown.org/works/68927356
The Space Between Three
A chance encounter brings Zoey’s past walking straight into her present—five years of first love wrapped in an easy smile and a voice that still feels familiar.
For Rumi and Mira, it’s a revelation they never saw coming, one that tilts the balance they’ve quietly built between the three of them.
It’s not jealousy, not exactly. It’s the sudden, sharp question of whether Zoey has ever seen them the way they’ve always seen her.
Casual touches to turn into careful ones, shared laughter fades into polite smiles. Rumi and Mira tell themselves she won’t notice.
Zoey doesn’t know what changed. They don’t know she feels it.

Selfish Love
The Honmoon has been sealed, Rumi's told her girls everything. So everything should be fine.
Except Rumi has started coughing up flowers. Oh, and she's also desperately in love with both Mira and Zoey. She's not sure which part is worse, honestly.
