Notes: Hey, everyone, sorry for the wait, I was having a bad time. Thanks for all the comments, I really appreciate them. Also, to the guest commenter, I'll see what I can do! Thank you! Day 12: Blush.

Adrien Agreste was a man of science.

It was, perhaps, his mother's fault. His father was clearly the unholy mix of a man of the arts and a businessman, combining the worst of both worlds, if Nino was to be believed. Adrien let out a soft protest at that, but couldn't really disagree. His father was all cold businessman and artist with a vision (Plagg often asked what vision it could be if he went dressed around like that and allowed Adrien to wear orange shoes, however, kwamis weren't allowed fashion opinions so he didn't pay attention to that). His mother was a completely different story.

Many people thought Emilie Agreste was an artist, through and through. After all, even with her outstanding beauty and ridiculous wealth, she worked in indie films and plays that managed to catch her fancy, managing her time between productions that made waves across France and small movies produced by a friend that had few copies to spare. Adrien knew better. His mother was also a gifted scholar, she loved studying things and figuring them out. He had asked her, when he was young, why she traveled so much and put so many acting jobs aside, and she had said acting was a hobby, learning was her life.

Like mother, like son then. Being an impressionable young child with only one friend and copious amounts of free time in his hands, Adrien tried to mirror the behaviour of the person he admired the most: his mother. He would join her in her study, very unlike father's, which was a little messy and always warm and welcoming and he was always allowed in before she got sick and everyone stopped caring about him. He would sit beside her in the little desk she commissioned just for him and study basic science, devouring book after book and falling in love with the way the world just worked.

"I'm gonna be a scientist when I grow up!" He said once at the dinner table. His mother smiled indulgently, but his father wasn't as kind.

"Don't be foolish, Adrien." He admonished. "You won't waste your time with such things, you'll work with me as a model. We can't let your perfect looks go to waste."

His mother didn't say anything to defend him, she never did. However, she winked at him as his father's eyes left him. He straightened up then, that little gesture never failing to make him feel like they both knew something his father didn't. These days, Adrien feels like maybe he hadn't know anything at all.

Anyway, no matter how much his father tried to discourage him, Adrien Agreste was still a man of science and that meant experiments! He would usually not try out a behavioural experiment, but it was, as a lot of good stuff in his life was, Nino's fault. Both had been discussing an art project with Alya and Marinette...

"This is really good, Marinette." He said sincerely, leafing through her and Alya's booklet.

Marinette seemed to shrink, blushing a little and smiling awkwardly, a sharp contrast to Alya, who only puffed up.

"I know, right?" Alya grinned, slipping her arm over Marinette's shoulder.

"I-it's nothing, really. Just a school project hehe." Marinette, taking the book back as Adrien offered.

"Everyone did theirs, but yours is a standout." Adrien said, smiling softly. Her work was amazing and he would say it as many times as it would take for her to believe it.

Marinette turned beet red at that, stammering something incomprehensible and dashing out of the classroom's door. Alya cracked out a laugh, quickly following after her. He watched them confusedly, scratching the back of his neck.

"Dude, you gotta stop doing that." Nino said, sighing.

Adrien raised an eyebrow. "Doing what?"

"Being all earnest and stuff." Nino answered, clasping his hands together and widening his eyes in a mockery of his best friend. "Oh, Marinette, you're so talented! You're so smart! You're so-"

"I don't talk like that." Adrien pouted. He didn't, did he?

"Yeah, you do." His friend snorted. "It drives the girls wild, even the ones that don't have a crush on you."

"You say that like a lot of girls have a crush on me." He rolled his eyes, other than his fans, the only ones who had a crush on him were Chloe and, the jury was still out on that one, Lila.

Nino gulped. "I mean, yeah, because of your fans and all! Not Marinette, she doesn't have a crush on you at all! She doesn't like you, even. She barely likes you as a friend!"

His heart fell. "Marinette barely likes me as a friend?"

"No! That's not what I meant!" Nino groaned. "Marinette does like you as a friend, okay, dude? I just word-vomited for no reason. Just don't go around being all you like that on her, she'll blush so hard she'll explode."

"Nino, you're exaggerating." Adrien had said, rolling his eyes.

"Yeah, you say that now, but try it with any girl and see how they react." Nino answered, mockingly rolling his eyes back.

He had shrugged at the time, but the question stayed in the back of his mind. Adrien was aware that he was good-looking, it was maybe the only thing his hard-to-please father ever complimented him on, but to make even girls that weren't attracted to him blush? It seemed very far off. However, he knew his mind wasn't going to let it go anytime soon. Adrien had a bad habit of not letting things go, Plagg said. So it looks like conducting an experiment was on the table and there was only one girl he would be comfortable trying it out with.

"Thanks, Marinette." Adrien said as he picked up a macaron from the box she brought to share with the class.

She flushed slightly, nothing so out of the usual that it would prove Nino's theory. "Y-you're welcome, Adrien."

"Did you help your dad make them?"

"Oh, I made them myself, I had some time to go to the kitchen lately." She said, eyes lighting up. "I missed it."

"It tastes great, Marinette." He said, making sure to smile and soften his gaze a little. It was actually hard to not do that around his friend, after all. "You're really talented."

Her face went fire truck red in a matter of seconds, mouth falling open and eyes going a little glazed over. Nothing out of the usual, but that was the thing: Marinette was always like that around him. Whenever he talked to her, a pretty blush would fill her cheeks and her blue eyes would go wide. Was he really so powerful that being earnest was enough to make a girl that only saw him strictly platonically blush like that?

"It's our raw magnetism, kid." Plagg told him solemnly when Adrien explained his theory. "Nothing we can do about it, girls better watch out."

They spared a minute of silence for all the girls struck by their lady killer charms.

"Hey, Plagg, when you say all girls…" His lady's adorable face flashed in his mind.

"Yeah, no, kid, dream on."

However, it must be said again: Adrien Agreste is a man of science and he would never fail to experiment on a hypothesis.

Their next patrol was quiet, jumping through the rooftops and climbing down to comfort civilians separately. He could feel Ladybug's eyes boring into his back at every confused glance she threw his way. The silence unsettled her, he knew that, but as much as he wanted to reassure her, he also had to create the perfect setting for his experiment.

"A bit quiet today, weren't you, Chaton?" His lady asked when they finally settled down, nonchalant tone costrating with her twitching fingers.

"Oh, I was just struck speechless." He said, voice purposefully serious as to not arouse suspicion.

"By what?" Ladybug frowned.

"By you." He smiled and she started to roll her eyes when he continued. "You're really kind, my lady."

She blinked owlishly. "What?"

"Every time I turn my back to you on patrol, when I look back you're talking to someone. Comforting that little girl whose ice cream fell, getting that kite stuck in a tree. It's not even just today, you always do that. I've never met anyone who does it as effortlessly as you do."

The words flew easily from his tongue. Complimenting Ladybug was often easier than not.

"You're really kind, Ladybug." He repeated, only to see her face darken until her cheeks settled into a rosy pink.

She opened her mouth as if to say something, but closed it again when she noticed it was hanging open. Her blue eyes went wide and shiny. It was the prettiest sight he had ever seen.

(Maybe being a man of science has its perks sometimes.)
