Dares.

Their entire class was familiar with them.

They often varied from rather mild, to, well, quite embarrassing or dangerous. And their favorite class jock was obsessed with making them. Everyone knew that when he got that little gleam in his eye, it was time to get the hell out of there before he trapped you in one of the challenges that were famous for getting people to do the most outrageous things.

Rose was forced into making obscene phone calls to random numbers other people shouted out.

Nino had gulped as Alya held up the razor meant to shave his legs, while Alix snickered with Kim in the corner.

He even dared Marinette, when their group of friends was out one day, to go up to a random kid their age and ask for his number. Adrien felt sorry for her, until she drew herself up with strikingly familiar determined azure eyes, and he suddenly felt sorry for Kim instead.

Their class begged for him to stop, they couldn't handle it anymore. So Kim made a deal with Alix, that if she beat him in a race, there would be an end to all dares.

Then she had been akumatized, and Kim hadn't made a dare since.

Until now.

- 6 years later -

"There's a 86.77% chance it won't work." The young man hummed, adjusting his glasses with one hand while his other was tapping away at the keys of his computer. His broad-shouldered friend next to him suddenly scowled, running his fingers through his usually gelled up locks in exasperation.

"Why? I don't even understand the math you're using." Max sighed beside him, shaking his head.

"Too much to explain, you'll have to just take my word for it." Kim rolled his eyes, leaning back in his seat. It took a moment, but his frown twisted into a sly grin, eyes flickering with flames of mischief. Max glanced over to see this, and he groaned. "You can't be thinking of…"

"Oh yeah, I am."

"You swore you wouldn't."

"It's probably the only way."

"However-"

"Will it help my chances?" Max hesitated, and Kim knew that he had won. "Then it's settled."

Max frowned slightly, but then turned back towards his computer, changing a few variable and typing in a couple of necessary numbers into his algorithm. He finally pressed the enter key, and watched as numbers shimmered into existence before his eyes. "Well?" Kim asked, peering over his shoulder. Max sighed.

"43.49% chance that it won't work." Kim remained silent for a moment, before a wicked grin spread across his face. He slammed his hand on the desk, standing up as he did so.

"I'll take it."

Marinette rose an eyebrow, though she wasn't looking at the young man that was next to her. Instead, her eyes were focused on the cupcakes that lined the counter before her, a pastry bag filled with luscious buttercream frosting held expertly in her tensed hands. She paused in her task, glancing up at the tall jock that was speaking to her.

"I thought you were done with dares." She spoke skeptically, blue eyes glittering with curiosity despite her slight annoyance.

"Just this last one, I need your help with it." Marinette huffed, turning her attention back to the sweet confections.

"It's been years," She hummed, frosting a perfect swirl atop the chocolate cake.

"C'mon, I'll even tell you what it is." This caught her attention. She hesitated before moving onto the next cake, instead turning her eyes towards him.

"... What is it?"

And then Kim told her his plan, and her bluebell eyes absolutely lit up with excitement, a soft smile dancing on her rose petal lips. She then sighed. "You have me convinced." She mused, before casting her gaze up the stairs.

"Adrien! Can you grab my keys from upstairs?" The blonde in question soon came down moments later, a ring of jingling silver keys swirling around his finger. He tossed them over, and Kim caught them out of the air.

"What's going on?" The man spoke, emerald eyes gleaming with the same inquisitive nature a feline's would. He strode over, arm curling around Marinette's waist as he rested his chin on the top of her head, staring over it at Kim. Marinette smiled, reaching up to dab a blob of frosting on his nose.

"I'll tell you later, minou, I'm just letting Kim use the roof of our flat." Adrien hummed in agreement, though his curiosity still shimmered around him.

"Have fun then." Kim nodded, tucking the keys into his pocket.

"Thanks Marinette, Adrien, I'll tell you how it goes."

"I don't know… I don't want to be involved in another dare." Alya grumbled from where she sat in the chair, Juleka armed with a comb and silver scissors behind her. The bronze eyed girl glanced at him, brushing long ebony locks behind her ear.

"Did you really have to come during her appointment?" Kim shrugged.

"Marinette told me where you were," He replied, and Alya sighed.

"Mari did? Fine. What do you want? Make it quick." And then Kim laid out his entire plan, including the dare, and Alya fell into silence. She didn't turn her head, as Juleka continued to snip at the bottom of her amber ombre hair, but then smiled slightly.

"Alright, I'll do it. If you text Nino, he'll take care of that too if you tell him I'm in." Kim grinned, pulling out his phone to message Nino as she told him to.

"Thanks Al, 8 o' clock sharp, 'kay?" She waved him off.

"Yeah yeah, I've got it, you just head to Mari's, Casanova." He smirked, and then rose a hand in farewell.

Marinette and Adrien lived on the top floor, so it was no surprise that the roof was theirs as well. It was mostly for Marinette, she had the greenest thumb that anyone knew, and it was filled with sprawling plants that exuded the scent and life of spring, even on this otherwise boring rooftop.

He, with the help of Nino, strung up what seemed like a million fairy lights, which blinked and glowed in a similar fashion to fireflies. As the day grew to night, they illuminated the rooftop. Courtesy of Nino's speakers, soft music played, weaving through the leaves and petals of the plants that littered the rooftop. He smiled, lighting a few candles that glowed on the surface of the small table they had set up, complete with a wine red tablecloth and a bottle of a similar drink to match.

"You all set, dude?" A hand rested on his shoulder.

"Yeah, I'm all set. Let Alya know it's go time."

When Alix arrived on the roof, she was a bit confused. Alya had said something about having drink with her and Marinette, but the other two girls were nowhere to be seen.

"Hello-ohhhhhh," She called out, annoyance glinting in her gaze along with a hint of curiosity. "I swear if this is some kind of joke-"

"Nah, no joke." The voice sounded from behind her, and Alix whirled around. Kim clicked a button, and the entire roof lit up with those firefly lights, glowing amongst flowers and brick alike. Her eyes landed on the man before her, and an amused grin came to the petite athlete's face.

"Now what's all this for?" She mused, hands on her hips. Her eyes glowed as she turned, taking in the scene.

"What did you have to say to get Marinette and Adrien to give you the roof?"

"Same thing I said to Alya and Nino to get them to help me set up." His voice brought her back from the reverie the fantastical scene had placed her in. She turned back around, and her eyes widened, breath catching in her throat.

She never thought she'd see the day where Kim had to look up at her, and not the other way around.

She rose a hand to her lips, just as he opened the velvet box he held in his hands.

"Alix Kubdel, I dare you to marry me."
