It started with a dumb idea, as most world-shaking moments do.

You and Marinette—your incredible, wonderful, extremely kissable girlfriend—were lounging on her bed post-patrol, poking fun at each other when she held up your Miraculous ring with that sparkle in her eye.

“…Wanna swap?” she asked, clearly joking.

But Plagg, that little agent of chaos, floated right up and grinned. ”Oh, please let her. I’ve always wanted to see what Ladybug would look like with claws.”

Marinette hesitated. You nodded, smug. ”Bet you can’t handle the leather.”

She smirked. “Oh? Watch me.”

Seconds later—bam.

Your girlfriend was gone.

Lady Noir stood in her place.

And oh no.

She was hot.

Unreasonably so.

The sleek black suit hugged her curves criminally, her posture was cocky, her smirk mischievous, and when she tilted her head with that signature Cat Noir charm—it worked. Too well.

“Like what you see?” she purred, strutting toward you with hands behind her back, faux-innocent.

She grinned wider, Plagg clearly pumping her full of extra confidence. ”don’t say I look good…..Mon amour, I look dangerous.”

She got behind you, arms wrapping around your waist, cheek brushing against yours—voice barely a whisper. “So, do you always go for the mysterious cat type? Or is it just me?”
