Summary
"Some loves are written in the stars—ours was written in the spaces between."
When Marinette and Adrien first become Ladybug and Chat Noir, their partnership feels like magic. But between secret identities, unspoken feelings, and the weight of saving Paris, their bond begins to crack.
This is the story of how they fell together, then fell apart—from clumsy rookie heroes to inseparable partners, from star-crossed lovers to bitter enemies, and finally, after years of distance and regret, back to each other.
A tale of love, lies, and second chances,where holding on is harder than letting go—and where even shattered trust can still spark like stardust.

Summary
Adrien runs away.
After a particularly bad fight with his father, Adrien decides to run away from home. His friends are searching, the police suspect foul play, and Gabriel starts to spiral. Meanwhile, Marinette can’t help but notice that something’s different about Chat Noir—he’s almost always around somewhere, ‘on patrol’ (wandering aimlessly), or scrounging around for food (much to the chagrin of local alley cats). As the two spend more time together, Marinette starts to realise that there’s more to her joke-cracking companion than meets the eye, as much as he wishes there wasn’t. -

Summary
I found this in the darkest depths of my Google Drive (apparently I was writing this at 3AM like a year ago) and decided to post it just for fun.
Basically, a mashup of a ton of my favorite fanfics and fan shows of Miraculous, and follows the plot line of Marinette moving to London after an incident at DuPont and meeting the beloved Quantics, while Adrien deals with her and ladybugs sudden disappearance and having to raise a newborn baby all alone in Paris. The story is the same until Season 6, and the story splits apart there.

Summary
Adrien Agreste never wanted to come to this boarding school in Paris. It’s full of rules he doesn’t understand, people he doesn’t know, and a world that feels impossibly out of reach.
Then he meets them.
Luka, the tattooed, cigarette-smoking frontman of a local rock band — charming, dangerous, and impossibly magnetic. Marinette, sharp-tongued, fearless, and his childhood best friend in this AU — the perfect partner-in-crime. And Kagami, fierce and protective, who knows more about Adrien than he realizes.
Adrien is supposed to stay out of trouble. He’s supposed to keep his head down. But in a school where rules are optional and boundaries are tested, Adrien learns quickly: sometimes the people you’re warned about are the ones who change everything.
Rebels. Secrets. Rivalries. And maybe, just maybe, love.

Summary
When French Minister Claude Dubois becomes the target of a deadly assassin known only as "Ladybug," elite government operative Adrien Agreste must go deep undercover to protect him. His mission: infiltrate a high-profile film production where the minister will be making regular appearances, and eliminate the threat before it's too late.
But Adrien isn't the only one who's taken an interest in the production of "Les Héros Silencieux." Marinette Dupain-Cheng, the very assassin he's been sent to stop, has secured her own role as a supporting actress—the perfect cover to get close to her target.
Now two of the world's most dangerous killers find themselves sharing scenes and red carpet events, each playing their part while hunting the same prey. As the cameras roll and the stakes rise, neither realizes their greatest enemy is standing right beside them, delivering lines and stealing scenes.
In a deadly game where every performance could be their last, Adrien and Marinette will discover that the most dangerous mission of their lives isn't the one they signed up for. Sometimes the deadliest weapon is the one you never see coming.
The show must go on. But not everyone will survive opening night.

Summary
“Guess who’s here to join you! Your new partner, here to save face and kick ass!”
Her head snapped up in the direction of the new voice. It wasn’t Rumi’s. Her gaze lingered shamelessly on his biceps.
“Oh. My. Gosh. Your biceps are hugeee!”
He raised his arm with a flourish, flexing them.
“Yup.”
The demon seized the opportunity and pounced on her. Eyes wild and raw, drool spilling from its mouth, and onto Zoey. Abby faked a gag.
“Do something! Don’t just stand there!” Zoey called out, tackling a demon to the ground.
-
During a late night demon attack, Zoey drops the Miracle box. What she didn't accept was for a stranger to find it, let alone for him to be so attractive.
