Chapter 1: Winter Weight

Description: After winter break, Marinette has gained a bit of weight that she wears back on the first day of school. Whether it's from the ridiculous amount of baked goods she was constantly snacking on or from her lack of exercise lazing around playing video games, she tries to lose it to keep up her fit super heroine image.

At the Dupain-Cheng residence…

"Marinette, you're gonna be late for school on the first day back from break!!" A busy Sabine called up to Marinette, rapidly overfilling Marinette's lunch bag with all kinds of cookies and pastries.

Upstairs, the red and black polka dotted Kwami helplessly tried to wake sleeping beauty to no avail.

"MARINETTE! WAKE UP!" Tikki screamed for probably the twentieth time into Marinette's ear, tugging it back and forth.

Marinette's eyes shot open as her dreamy drooling state was interrupted by the collective nagging of Sabine and Tikki.

"What time is it?" Marinette groaned and stretched accidentally knocking the empty cookie tin off the foot of her bed.

"Home room with Ms. Bustier started five minutes ago!"

"WHAT!?"

Marinette threw the covers off her bed, jumped out of her pajamas and threw on her usual pink jeans, embroidered shirt, and cute blazer. Her pants were oddly difficult to button, so in an embarrassed scramble she used the hair tie method to secure them. Even then they were a little tight so in frustration, marinette grabbed her loosest pair of sweatpants and changed into those.

"Much better…"

Then she scurried into the bathroom with the tenacity of a wolverine, wiping the cookie crumbs from her lips, while washing her face and brushing her teeth. In a whirlwind of multitasking, she quickly whipped on her favorite eyeliner, mascara, and lipgloss, using the occasional concealer to hide the sleepiness from her face.

"Marinette…" Tikki reminded her.

"Alright we're going, hop in," Marinette gave Tikki a smile and tapped on her favorite purse, in which Tikki quickly hopped in.

She ran down the doors, hugged her mother goodbye, and ran away with her lunch and a few extra sweets for Tikki.

The first half of school went by quickly. During lunch, Marinette happily scoffed down the mountain of sweets her mother had packed her. Adrien kept staring at her while she ate which just made her eat more and quicklier. A blush heavy rising to her cheeks she finally couldn't stand it anymore.

"Adrien, would you like o-one of m-my…"

Get it together, Marinette. She gulps, brushing the nervous sweat from her brow,

"... do want you a pastry?" Her eyes practically pooped out of her head in embarrassment, "—er I mean do you… want a p-pastry, Adrien?"

"I really wish I could, Marinette," he sighed and gestured across the parking lot, "but ever since my father instructed Gorilla to watch me during lunch, I haven't had a chance to sneak any of your amazing treats."

But that doesn't mean Chat Noir wouldn't be paying you a visit tonight for some baked goods, my Princess… Adrien sighed at the thought. He then continued to watch Marinette eat. She looked different somehow and he was still trying to figure out how. Maybe if not as Adrien, he'd figure it out as Chat.

Lunch passed as soon as it had started. Next period was gym where Marinette ran into an unexpected issue.

"Alya!! Can you come here?" Marinette called to her best friend in utter disbelief as she stared down at her gym shorts which were suddenly inexplicable tight around her hip, ass, and waist.

Alya slightly pulled back the communal shower curtain and took a peek inside.

"Ohh, girl. You just gained a little winter weight, that's not a problem. Good thing I carry a spare pair of gym uniforms in my size. I'll be right back…"

"What? No! These must've just shrunk in the wash or some—"

She reshut the curtain before Marinette could finish her thought.

"—thing…" Marinette frowned and poked at her stomach while shimmying out of the tight gym clothes.

She hadn't thought she'd gained any weight over break, I mean she'd always been able to eat as much as she'd wanted and then she'd just end up losing whatever she gained by being Ladybug. But now that she thought about it...

She'd maybe patrolled twice over winter break, there had been no Akumas, and Tom and Sabine had doted on her with so many special Christmas sweets that she nearly had to stuff herself to the point that she felt sick every day in order to keep up with the never ending plates of sweets she was given.

Marinette loved sweets and eating so much that she'd been so distracted during break that she hadn't noticed the changes in her body. But first this morning with her jeans, then the ravenous appetite for sweets that she had at lunch, and now with her gym clothes being uncomfortable snug… she felt somewhat self-conscious.

Had other people noticed besides her and Alya?

Oh God… Adrien must've thought I was such a pig at lunch…

Marinette swallowed nervously. Did Adrien notice she'd gained weight? She changed into Alya's gym clothes and examined herself in the mirror. Thankfully, she didn't look that different. She'd maybe gained 5-10 pounds. She could tell the difference if she looked at herself without her clothes on, but what difference would 10 pounds make?

Apparently a lot— gym was hell. Marinette was huffing and puffing, gasping for breath, barely keeping up with the rest of the class. Everything she did, she did slower, clumsier, and with far more effort than the rest of the class. God, she was supposed to be the epitome of fit. She was Ladybug after all. Yet now she could barely keep up with her class.

"Haha! Somebody's out of shape, Dupain-Cheng!" Chloe Bourgeois, possibly the most annoying person alive, sneered loudly for the whole class to hear on her way to the girl's locker room.

"Don't listen to her Marinette, even my mile time went down over break," Kim, the school's track star, rolled his eyes towards Chloe.

Marinette ran home quickly after school, right past Sabine and Tom in the bakery and straight up to the bathroom scale.

She ripped all of her clothes off for even more accuracy.

"WHAT!?" She groaned, "Tikki, it's even worse than I thought."

The scale read 140.8 lbs, as opposed to the 125.2 lbs she went into break with.

"Oh… c'mon Marinette, so you gained 15 pounds because you enjoyed yourself for once and didn't have to worry about any Akuma attacks. So what?"

"So what?! How am I supposed to be Ladybug if I'm not at my peak fitness level? How is Adrien even gonna consider liking me if he's always hanging out with models who are skinnier and prettier than me!?"

Tikki sighed and flew right up to Marinette, "Do you really think someone as pure of heart as Adrien is that shallow? You're beautiful Marinette, no matter what number shows up on that scale. As for being Ladybug, please don't tell me you haven't already figured out that the power of the Miraculous amplifies the strength and agility of its holder?"

"... What will Chat Noir think…?"

Suddenly there was a knock on Marinette's balcony window.

Tikki smirked, "I think you're about to find out."

End of Chapter 1 :)
