Marinette and Adrien are both Littles.

Usually after a child enters high school, they are brought in to a medical and psychological professional to judge their classification -- Alphas, Betas, Omegas, Caregivers and Littles -- and are often sent to a high school within the school system that caters to that specific class. If a child is found to be a Little, they are brought to a specialized "Little School" where they can be educated and cared for, not unlike a Daycare center that teaches high-school-level subjects.

Collège Françoise Dupont was what you would call a "co-ed school". Most schools would adhere to certain classifications of people, but because Dupont receives more-than generous donations from two wealthy benefactors, the school has since changed its curriculum and made itself more accommodating to every classifications and has admitted students from every category.

The bell rang, signifying that class was over, at least for lunch.

Various students stood and walked out.

In the center-left row, Marinette and Alya were packing their books, pencils and paper away into their backpacks; Marinette having a bright-pink Hello Kitty backpack, Alya a plainer orange backpack.

"Alright, first thing's first, let's get you changed," said Alya.

Marinette mumbled something, briefly forgetting that she was sucking on a bright-pink pacifier before taking it out. Being a little, Marinette was aloud certain luxuries under certain circumstances. Since littles possessed an unavoidable oral fixation, she was allowed a paci in non-interactive parts of class-time. Since most of today was catch-up time, she was aloud free-reign to suck on her paci to her heart's content. It made her feel warm and fuzzy to do it.

Alya gripped at the end of Marinette's skirt -- the little deciding on a bright-pink sundress that she made herself over the weekend -- and hiked it up. Instead of big-girl underwear, Marinette was wearing a bright-pink diaper covered in decorative patterns that gave it the look of a flower-garden, leaving the rest of her legs naked down to her socks and velcro shoes. Alya placed her hand on the diaper, getting a feel for it.

"Hmm, you went pee-pee a little bit, but I think you can keep it on for a little while longer. Now let's get lunch for that empty belly," said Alya as her fingers suddenly darted and tickled Marinette's stomach. The little responded with a happy shriek of surprise followed by laughter.

"Okey, Alya," said Marinette as she giggled like a toddler.

You can tell from the tone in Marinette's voice that she was beginning to slip into her "little" headspace. Marinette was usually very good at keeping her mind clear during class-time, but since today was just a workday, her lack of focus tended to make her slip and her babyish side leaked in while she was working on her Chemistry homework when she was working.

Luckily for her, her best friend Alya was a Caregiver who more than happily applied to be her caregiver during school hours. Alya took her hand as they both stood up and left the room.

Meanwhile at the front of the class, Adrien was putting the finishing touches on his essay, Nino had already packed and adjusted his

"Dude, I'm headin' to Andre's for a triple-scoop. Wanna come?"

"Um, no thanks. My father wanted me to catch up on a shoot later on and I can't miss it."

"You sure? I mean, what's it gonna hurt if you miss a few minutes for ice cream?"

The Little in Adrien perked up at the mention of ice-cream and felt like tearing up when it realized that he couldn't do that, but he swallowed it all and politely declined.

"Well, alright. Maybe some other time."

Reluctantly, Nino put on his headphones and headed for the door.

As Marinette, Alya and Nino left, Adrien waited until he was entirely alone. He gave an exasperated moan as he slouched back in his chair. He hiked his t-shirt up and tugged at his jeans - the material made of an elastic denim - and got a good look at his underwear. It was a pair of pull-ups, made for boys his age, Remy from Ratatouille holding a cooking spoon printed on the front. Marinette wasn't the only one who wet themselves during class, and Adrien's pull-up had almost reach capacity.

While Littles weren't incontinent per-se, they had a much harder time holding it and would have accidents, thus the default undergarment for them were diapers and other forms of accident proof undergarments.

When Adrien and Amelie came home from the doctor with news that their little boy was in-fact a Little, Gabriel became even more overprotective than before. When Amelie disappeared, Gabriel's overprotectiveness went into Draconian levels to the point where he was barely ever aloud out of the house. Round the clock nannies, specialized tutoring to nurture his young mind, baby-proofing the entire mansion, replacing all of his clothes with matching onesies and all the building blocks he could ever ask for.

Gabriel was an Alpha, so all he ever really knew was how to take charge and protect his family, but Adrien felt like he was trying to keep Adrien in his little headspace 24/7.

When the school-year started, he snuck out of the house in the most conventional big-kid clothes he had on and made his way to Dupont. While Gabriel was furious at first, he eventually agreed to let Adrien attend public school, but not after a few caveats. He agreed to allow Adrien to attend as a normal student and even let him take on some more "grown-up responsibilities" befitting his age like his modeling and music-playing, but only after Gabriel made a massive donation to the school so that he made sure that it was a safe place for him. He was only allowed to leave the building as long as Natalie or the Gorilla came to chauffeur him, meaning he wasn't allowed to leave for any reason other than to go home. While Adrien didn't mind indulging in his headspace and being a baby a fraction of the day, it wasn't healthy for him to be a baby all the time and he was aloud to act like a normal teenager at school.

It wasn't a perfect situation, but he wasn't one to argue.
