I'm Marinette's WHAT?!

Origins Part 1

Y/N sighs as she looks through the Miraculous salt on her computer. She's become practically addicted to it and agrees with so many points, but at the same time, sticks around, hoping the show will get better. She strokes her hand through her H/C hair.

"Y/N, honey, it's time for bed." Her mother calls.

Y/N groans. She's a legal adult, she doesn't need bedtimes. (Unless you guys are not, then in that case, ignore the last sentence.) She plugs in her earplugs, playing the last song on her playlist, which happens to be Stummer Shrei by Anna Blue. (Have a listen. It's really heartwrenching, even in German.) As Y/N closes her E/C eyes, she starts to drift off, the song becoming quieter as she falls deeper into her slumber.

Y/N opens her eyes and yawns, only to feel something different. She sits up, feeling slightly shorter/taller than before. How does she know she's smaller/taller? Her feet were definitely not that size when she went to bed. She goes to turn her head, only for her body to ignore her and just crawl to the ladder off the bed. Wait, LADDER?!

Y/N goes to move her hand in front of her face, which it ignores as it reaches for a familiar shirt.

"Holy crap." Y/N goes to say, but her mouth doesn't open.

Well, it's not her mouth, is it? The body walks over to her mirror to show Marinette Dupain-Cheng.

"No way!" Y/N exclaims, her voice only heard by herself in her own mind.

"Who said that?" Marinette asks, whipping her head around.

Y/N blinks, "You can hear me?"

Marinette answers, "Yes. Who are you?"

"I'm Y/N. I think I've just become, like, either your imaginary friend, your inner demon, your conscious, or your alternate personality." Y/N frowns.

After a long explanation, the two found out that they could communicate with just their thoughts. Y/N's become close to Marinette, and Marinette's bonded with Y/N. The girls just chuckle in each other's minds, and Y/N and Marinette have been able to let the other take control of Marinette's body. It was an interesting feeling, to say the least. After a while, about a week, Y/N's found a way to give Marinette privacy and to have privacy herself inside Marinette's mind. She's made herself a nice little mind room, kind of like Sherlock's mind palace. Marinette and Y/N meet each other in their dreams all the time. But so far, Y/N's found no sign of Tikki, so it must be before she gets the Miraculous.

"Marinette! Your alarm's been going off for fifteen minutes! You're gonna be late for your first day back at school." Sabine calls from downstairs.

Marinette groans, "Got it, Mom." (The only reason I said Mom is because it's an American show. I'm Aussie, so Y/N's dialogue will say Mum.)

Y/N immediately realises what day it is.

"Do you want me to take over while you're waking up, Nettie?" Y/N asks.

Marinette smiles, "That would be nice."

Y/N pushes herself into Marinette's body and picks out the regular Marinette outfit for today. Let's not change anything just yet. She quickly gets changed, trying to ignore Marinette's overly skinniness and failing.

"Marinette, how the heck are you so skinny from living in a bakery?!" Y/N asks Marinette mentally.

She feels Marinette shrug sleepily.

"Coming Mum!" Y/N calls as she walks down the stairs.

Y/N kisses Sabine on the cheek like she's done to her own parents so many times before.
