Summary
"Let me make sure I have this right," Chat Noir said. "Ladybug got not one, not two, but five of her friends akumatized at once… because she didn't want to tell them she was Ladybug."
Ladybug laughed, but this time it wasn't a joyful sound. It was hard and dry, like a month-old jelly doughnut. "Yeah, that about sums up how absurd my life has been recently. I didn't need to be so nasty, but in my defense, I was panicking; they almost found the Miracle Box. Anyway, after you left… after the fight… we all made up and they promised to wait until I was ready to tell them my secret and stop pushing me. But Alya stayed behind after everyone else went home, and I think she was expecting me to tell it to her anyway. I almost did, but I… didn't."

A Miraculous Ladybug AU where Marinette does not reveal her secret to Alya after Gang of Secrets, but to Adrien instead. Somewhere along the way, Chloé finds redemption.

Summary
In this AU, Marinette is Multimouse, Adrien is Aspik/Flairspik and Alya is Scarabella/Rena Furtive. None of them know each other's secret identities except Alya and Marinette, who have already shared them before this fic.
The love square of Marinette, Aspik, Multimouse and Adrien is virtually the same as the canon one, but for the fact the holders have different Miraculous.prompt: 'snekmouse'

Summary
When Marinette was a little girl, she had a friend. He never spoke, never told her his name or anything of the sort, but he was he best friend reguardless. He always followed her everywhere, people would sometimes forget he was even there because of how silent he was. Everyone called him her shadow, matching her move for move, going where she went without a word. It was a fitting name.
Shadow disappeared when Marinette turned 8, he only came back 3 years later when she was 11. He came back different, changed in ways she couldn't explain.
Now, at 18 years old, Marinette needs his help. Will he answer her call?

“I don’t quite like the look on Marinette’s face right now…” Ziggy whispered to the other Kwami's, “She has this crazed look in her eyes.”
“I’m not crazy, Ziggy,” Marinette stood up from her chaise, her tired, baggy eyes wild as she gestured to herself, “I’m a genius. I don’t have to give up my civilian life permanently!”
“See, Marinette! I told you that you didn't have to give up your civilian life! You just need to—”
“Fake my own kidnapping! There are no flaws in that!”

“We’ll just need to find you a home before she defeats him.” Chloe sprung forward slightly in excitement, eyes wide as she exclaimed, “Oh! I know! You could ask Wayne!”
“Uh,” Marinette looked at the others and saw their expressions were just as blank as her own. “Who?”
“Bruce Wayne!” Chloe stuck her nose in the air as her smile turned over-confident with a hint of know-it-all. “That American Billionaire. He has a penchant for adopting kids with tragic backstories, and you’re just his type. Dark hair and blue eyes, and he’d love that whole ‘Goody-Two-shoes’ thing you have going on. I bet he’d adopt you in a heartbeat!”
“Sure, Chloe. I’ll just send him the adoption papers with a ‘Congrats, it’s a girl!’ letter.”
