I was originally just going to leave this as a oneshot, but since you guys liked it so much, I'm going to continue it! Thank you to everyone who reviewed, followed, or favorite! And an especially big thank you to the reviewer who pointed out that it's Chat Noire.
Marinette's head is filled with thoughts of Adrienne as she hurries off to her favorite drawing spot. She'd complimented her drawings! And, thanks to Alya, Adrienne had known that they were her drawings. Alya really was the best friend ever! She'd have to thank her later.
She'd been so dazzled by how pretty Adrienne looked that she'd barely been able to speak to her. It was completely unfair how Adrienne managed to look good no matter what she wore; even in the oversized shirts and jackets she wore to school, so different from the pretty dresses she wore while modeling, she still looked amazing! Marinette was thinking hard. She'd have to come up with a design worthy of Adrienne's beauty.
Meanwhile, Adrienne is unhappy about being the center of attention. At school, she tried to avoid mentioning her modeling career, but her father had insisted, and she really wanted to make him happy. But it meant that Chloe had spent all morning bothering her, trying to get hints about what to make for the contest. Now, judging by the look on Chloe's face, she's up to something. Adrienne just hopes that whatever it was won't disrupt the design contest and make her father angry.
After Adrienne runs out, Marinette is too lost in thought to hear what Alya's asking. She does a mental comparison between Chat Noire and Adrienne Agreste: they're both allergic to feathers, and they both have blond hair and green eyes. "Hello! Earth to Marinette!" Her brain finally catches up to what Alya is saying.
"Oh! Sorry Alya!" she replies sheepishly, finally noticing her friend's attempts to get her attention.
Her best friend just shakes her head at her. "I was asking if you want to go get ice cream to celebrate."
Marinette lights up at the idea. "Let's go!" she says enthusiastically, and Alya nudges her in the direction of the ice cream parlor. "I can't believe Adrienne is going to model our design!" she squeals.
"I knew you'd pull through for us!" Alya does a fist pump. "So what were you thinking about?"
"Oh, I was just daydreaming," Marinette replies quickly, shaking her head. She decides that there's no way the flirty, confident Chat Noire could ever be the humble, quiet Adrienne Agreste. The differences in their personalities are too great.
Later that evening, Chat Noire and Ladybug meet on the rooftop to patrol Paris. They don't patrol every night, but they make an effort to patrol the evenings after an akuma attack, to make sure that they don't miss anything. Usually, Chat Noire will show up a few minutes late, making bad puns and ready to help guard the city. Tonight, she shows up early, only a minute after Ladybug, and she seems withdrawn and pensive.
They start out on their patrol, moving west first. Usually, Chat Noire will be flirting and making small talk. Tonight, she's silent as they move along the rooftops. Finally, Ladybug is the one to break the silence. "Chat Noire? Is something wrong?" she asks, trying to sound casual.
They come to a stop, having reached the western edge of their route. Chat Noire stares at her feet for a second, then blurts out, "I'm really sorry about today!"
Ladybug is puzzled. "Sorry about what? You didn't do anything wrong."
Chat Noire shuffles her feet awkwardly. She mumbles, "I messed us up today, because of my allergies."
"Oh, that?" Ladybug waves a hand in the air dismissively. "That wasn't your fault. You couldn't control it. And you didn't mess us up! You came through for me like you always do." She shoots Chat a reassuring grin.
Chat blushes at the praise, running a black-gloved hand through her long blond hair. "You think so?"
Ladybug puts her hands on her hips. "I know so. We're partners, and I know you'll always have my back. Now, how about we get back to patrolling the city?"
Chat Noire smiles, and she seems more like her outgoing self. "You can count on me, my lady!" She turns, and soon they both are sprinting across the rooftops, only lit by the light of the moon.
