It started on a rare day when the girl's PE Instructor was ill and the girls were forced to sit in a classroom with a worksheet on anatomy.

Without teacher supervision.

So of course they googled the answers on their phone and immediately turned to do something much more interesting. Gossiping instantly turned into joking about which then, inevitably, changed into Truth or Dare. It was already steadily getting out of hand with Alix coming up with some wicked dares, Chloe yanking out the most horrible truths, and Alya doing a little bit of both.

Marinette was really beginning to dread her turn again. It had been bad enough when she chose truth and Alya got her to dredge up every detail of her feelings for Adrien to which Chloe scoffed at and insult her about, and everyone else looked painfully sympathetic to her. Now as Chloe had made Alix flash the world while in return was currently being forced to wear a sign reading 'I'm a Massive Bitch' (thanks to Rose much to everyone's surprise), and Sabrina had been recently forced to admit to five years of bed-wetting, Marinette was rather scared at what will happen to her next.

"Alya," Alix said loudly as she pulled her t-shirt down and turned back from the window, "truth or dare."

"Dare," Alya said lazily, "of course."

"All right," Alix grinned mischievously. "I dare you to lick Chloe's cheek."

"What?!" Chloe shrieked. "Ew! No! Try it and I'll make your life a misery."

"You already do," Alya rolled her eyes. Chloe glowered back and crossed her arms sulkily when Alya then suddenly lunged forwards. Chloe's eyes widened with horrified realisation and she tried to run away when Juleka and Rose grabbed her by the arms and held her still. "Stay still," Alya said in an evilly sweet voice, "It'll just take a second."

Chloe squirmed against her capturers. "Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!" Chloe wailed as Alya's pink tongue stuck out and rolled itself across Chloe's perfectly made up cheek. Her foundation and blush smudged ever so slightly as Chloe let out another, pitiful, and wordless wail.

"Ew!" Alix cackled. "That was disgustingly awesome."

"It was disgusting," Alya agreed as she grimaced. "Jesus girl, how much make-up do you wear?"

"What?" Chloe sniffed huffily. "It takes a lot to look this perfect."

"Perfect for what?" Alix smirked. "To scare away little kids?"

Chloe huffed. "When my father hears about this-"

Majority of the classroom rolled their eyes at that "No one cares!" the girls all chorused with impatience and irritation.

"I care," Sabrina said as she patted Chloe's shoulder, "and I think you're all so horrible to inflict such torture on poor, innocent, Chloe."

Everyone else snorted at the idea of Chloe being innocent but decided to let the matter drop unless they wanted to end their period of freedom in a bitter argument where undoubtedly someone would end up Akumanised because Chloe has apparently made that her newest hobby.

"Marinette," Alya smirked as she turned her attention back onto her best friend, "Truth or Dare?"

"Truth! No! Wait! Dare! No! I mean Truth! No!" Marinette babbled nervously and rapidly as she tugged at a pigtail anxiously. "I mean….erm….ah…..I…."

"Oh for God sake!" Chloe snapped impatiently. "Just pick one! Either way you won't like it, Marinette Dupain-Cheng!"

Marinette gulped. She already had one of her darkest, biggest, secrets ("It really wasn't a secret," Rose said in a poor attempt to comfort Marinette when she wept with shame earlier) and she really didn't want any others to come out. Could Tiki ever forgive her if a game of Truth or Dare somehow resulted in half of Paris knowing her secret identity? Probably…..but Marinette really didn't want to find out.

"Well then…." Marinette said timidly, "I'll do a dare….yes," she nodded firmly and decisively, "dare!"

"All right," Alya smirked evilly, "I dare you to go down to the boys' locker rooms, grab Adrien, and kiss him!"

"What?!" Marinette squeaked. "Alya!" she gasped fearfully. "I couldn't do that! I'd get into so much trouble if the teachers saw me go in!"

"And she can't kiss Adrien," Chloe butted in furiously, "because Adrien is mine! It's sexual harassment to force the pathetic-ness that is Marinette on my poor Adri-kins! The feel of her horrible, slimy, lips will traumatise him for life!" Chloe said melodramatically. She pouted but then after a second of silence her lips formed an evil smile. "And then, of course, he'll forever be put off of her. So why not?" she shrugged in a sophisticated manner. "Go get your kiss. You'll never have a second one Marinette Dupain-Cheng as Adrien will never want anything to do with you again."

"Don't listen to her, girl," Alya said quickly as she took Marinette's hands and squeezed them reassuringly, "Adrien isn't like that. And you're so cute that I bet he won't be able to resist you."

"Yeah!"

"You're so pretty Marinette."

"I agree."

"Adrien would never be so mean to you."

Marinette flushed as all the others (barring Sabrina and Chloe) all chimed in their agreement with Alya. "But….but….but…." she stammered, "what if I don't want to do it?!"

"Girl," Alya said unimpressed, "don't lie. We all know you want to kiss him."

"…Yes," Marinette said slowly, "but not as a dare."

"Think of it as an opportunity to confess your feelings," Alya said soothingly, "and you don't have to do it. You have the option to do the forfeit instead."

Alix and Chloe snickered at that while Mylene suddenly burrowed into her hoodie and covered her face. She had chosen Truth earlier and when pressed for some intimate details about her relationship with Ivan, she clammed up and took the forfeit.

Which was to streak across the corridor naked.

(Seriously they were so lucky that none of the teachers have bothered to check in on them or they would so be in detention right now.)

Given the choice of potentially embarrassing herself in front of a small group of boys or embarrassing herself in front of the whole school, ending up in detention, and having to explain this to her parents, Marinette knew that there was really only one choice….

And that was how she ended up outside of the boys' locker room door trying to psyche herself up to do the deed.

"Come on Marinette!" she whispered fiercely to herself. "You're Ladybug. You eat dangerous situations for breakfast and spit them back out. You can handle one measly kiss. You can do this! You can do this! You can – oh my god!" she flung herself to the wall and clutched at it desperately. "I can't do this!" she wailed. "Chloe is right! Adrien is going to be so disgusted that he'll end up filing a restraining order against me and then I'll have to swap schools, and they'll force me to register myself as a sex offender and I'll never ever get a date in my life again."

"Okay, now you're being ridiculous," Tiki said chidingly as she floated out of Marinette's purse, "first, you would not be registered as a sex offender for kissing a boy, secondly, Adrien would never go that far in rejecting a person or otherwise Chloe would have one taken out on her months ago, and thirdly, and I can't stress this enough, you don't have to do this!"

"I have to!" Marinette wailed. "Or they'll make me streak across the school!"

"They can't make you do what you don't want to do, Marinette," Tiki said sternly. "Don't give into peer pressure. You're better than this."

Marinette shook her head. "I can't let Alya down or Chloe win," she said quietly, "and also….I kinda do want to do it," she admitted sheepishly.

Tiki gazed at her with an impenetrable gaze. Her dark eyes boring into Marinette and making her feel extremely uncomfortable and nervous again. "All right," Tiki replied softly, "I can't stop you."

Marinette inhaled deeply, gathered all of her Ladybug courage and strength that she could muster, and then breathed out as she held her head up high and proud. "I'm ready," she said firmly.

And with that she pushed the boys' locker room door with all of her strength resulting in a great, big, loud –

BANG!

All the boys, who had been in the process of getting changed, suddenly jumped. Nino let out a strangled, high-pitched, scream as he ducked to cover himself as much as possible with his shirt. Nathanael threw himself against the floor, Max clutched his trousers to his chest, Kim clutched his bag to his crotch, and Ivan and Adrien merely looked startled as they were already dressed and had nothing to hide.

"What the hell Marinette?!" Kim burst out. "Did you mistake this for the girl's toilets again?!"

"Seriously dude," Nino yelped, "Learn to read the sign on the door!"

Marinette ignored them as she strode across the locker room determinedly towards Adrien. "Erm," Adrien murmured nervously as he took in the strange, stubborn, glint in Marinette's eyes, "is there something I can help you w-hmmph!"

Marinette didn't even give Adrien a chance to finish his question because he if did she would be obliged to answer and if she answered she would have just stammered, made gargling noises, and embarrassed herself so much that streaking through the school might have ended up as a very attractive alternative. So instead, she grabbed Adrien by the collar of his shirt, pinned him against the locker, and covered his lips with her own.

The boys' jaws all dropped wide open as they gaped at Marinette and Adrien unattractively. Adrien flailed wildly, his arms going in all directions against the lockers, as he desperately tried to cling onto something while Marinette deepened the kiss ever so slightly.

And then as quickly as it happened, Marinette suddenly pulled away. Breathless, bright pink, and suddenly shy. "That was all!" she muttered quickly before she released Adrien and suddenly whirled round and walked out of the locker room extremely fast. Her arms moving stiffly as if she was a robotic soldier or something.

Adrien's knees buckled slightly as he slid against the cold metal of the locker and onto the floor.

"Oi, Adrien," Nino cried out, "are you all right?!"

"Guh!"

"OH MY GOD!" Marinette heard Kim bellow just as the locker door slammed shut behind her. "MARINETTE BROKE ADRIEN!"
