(Summary: Lying about dating Adrien. Really, Lila?

I realised that I haven't written a oneshot about this and I had to rectify that fact immediately.)

When you're famous, there will always be rumours swirling about you dating this person or that. And you know, it's pretty strange, but you get used to it.

But when Lila Rossi, the living embodiment of a tabloid claims that she is dating you, you're bound to be a bit annoyed.

To be honest, Adrien was more than a bit annoyed.

It's the fact that everybody believed Lila. That they didn't doubt the fake hickeys on her neck or the grating giggles she let out.

Adrien suddenly understood why Marinette hated the liar so much.

Lila's final lie was spoken on a day, much like today, which was only yesterday, and it wasn't even technically her last lie because Adrien had also heard her claim that she was actually Elvis Presley's sister's husband's cousin's stepson's dog's brother's owner's second cousin-in-law.

But let's not dwell on those minor details.

"Lila, where have you been?" he heard Alya hiss behind him as Lila walked in after him. Adrien thought that the answer was fairly obvious. After all, he had seen Lila lingering outside the classroom door determinedly.

"What do you think she'll say this time?" Marinette questioned behind him as they trudged up to the back row of the classroom. After they had started dating, they had convinced Mlle. Bustier to let them sit together. Of course, they'd given her a bullshit reason, but she believed it because of course she did. Adrien hadn't really wanted to move away from Nino, but this at least gave them some freedom from Lila.

"Hm, Tinnitus?"

"Too obvious," Marinette frowned. She perked up suddenly, her eyes sparkling with mirth. Adrien almost missed what she'd said─hey, when somebody looked this beautiful, you can't just ignore it. "Look at how she's holding her neck. Maybe she got attacked by a rabid dog and now has some incredibly rare disease."

Adrien snickered. "Maybe it was a vampire." Marinette grinned, leaning her head against his shoulder.

A loud squawk from Alya caught their attention. "Girl! Is that a hickey?!"

Lila flushed red, shifting her hair to hide it from view. "N-no!" Adrien didn't miss the embarrassed look she sent him. He shifted uncomfortably, grabbing Marinette's hand under the desk.

Alya laughed. "That is definitely a hickey! What have you been up to, girl?"

"N-nothing!" By now, the two had attracted the attention of the entire class.

"I don't think that's nothing," Rose giggled, grinning at Lila.

"Who is it?" Alya interrogated. "Is it somebody we know─" Lila averted her gaze. Alya gasped in delight. "So it is! Who?!" Alya cast a suspicious look around the classroom. Adrien could see who Alya was writing off. The obvious ones went first, Nino, Ivan, Nathaniel and Max. Alya narrowed her eyes at Kim for a moment before shaking her head and looking at the back row. "Oh my God! Girl! You and Adrien?!"

"What?" Chloé looked up.

"What?" Adrien winced as Marinette's grip on his hand tightened.

"WHAT?!" By far, Adrien was the most shocked. He never would've thought Lila would try… this!

"Alya!" Lila hissed. "It was a secret for a reason!"

"Why?" Rose's head tilted in confusion.

"Let me guess," Alix leaned back in her chair. "Adrien's dad being awkward again."

"Y-yeah," Lila blushed, fidgeting with her dull, brown hair. "H-he didn't want us to tell anyone in case it got to the press. They're… very persistent."

"Bro," Nino looked at Adrien. "Why didn't you tell me, though? I'm your bro!"

Adrien sighed. "I'm not dating Lila."

Panic swept through Lila's face for a millisecond, but she quickly put on a simpering smile. "It's okay, Adrikins. They already know. There's no point lying to them."

"But I'm not─"

"Anyways," Lila interrupted him. Nino looked suspiciously at Lila, but Lila's eyes were focused on the person sitting beside Adrien. "Marinette, I really hope you aren't mad. I know that you─"

Marinette didn't even look angry. Her expression was icy. Adrien had to suppress a shiver as Marinette leaned forwards, smiling sweetly. "Why would I be mad, Lila? After all, I'm used to this."

"This?" Alya frowned at her dangerously.

"You know, Lila coming up with something outlandish, you guys believing her, not even bothering to consider the fact that she mightn't be telling the truth… you know, normal stuff."

"'Normal stuff'?" Alya repeated. She scoffed loudly. "Girl, I get that you're jealous of Lila, but─"

"Look, Alya." Marinette leaned back, crossing her arms. "There's no point having this argument because you're going to refuse to listen to me, get angry at me when I present evidence to you, demand more evidence, and like a hypocrite, tell me that I should check my sources. Even though you've never checked your own. So we're not having this conversation."

The entire class was speechless as Marinette glared at them. Adrien grinned, leaning down to whisper into her ear, "I'm proud of you, M'Lady."

Marinette didn't have a chance to reply as Lila let out a loud cry. "Really, Marinette?! First you call me a liar and now you're trying to steal my boyfriend! I─I can't believe you! I thought you were my friend!"

Marinette blinked at Lila. Adrien tried to suppress his laughter, he really, really did. "Since when?" he asked.

"Adrien!" Alya jumped up. "She's your girlfriend! You're meant to be on her side!"

Adrien stared back at her. "I am on my girlfriend's side."

"Doesn't seem like it," Alya grumbled, lowering herself back into her seat.

"I think it's fairly obvious," Adrien said, squeezing Marinette's hand under the table. He heard a soft gasp and looked across the row at Nathaniel. He grinned, shaking his head at the redhead. Nathaniel's eyes were wide as he looked between them and Lila. He never said anything, though.

No further argument could be made as Mlle. Bustier finally arrived.

Marinette turned to him. "We have to do something about this."

"You know if we tell them we're dating, Lila will just spin things to make you look bad."

Marinette smirked. "So we spin things to make Lila look worse."

Adrien leaned forwards, grinning. "I'm listening."

When Marinette and Adrien walked into class hand in hand, only a couple of people noticed. Rose looked between them and Lila in confusion, Nathaniel ducked his head as he laughed and Nino gaped at Adrien. When Adrien kissed Marinette's cheek, Alix frowned and Kim let out a strange noise, loud enough to draw the attention of the rest of the class.

"Oh my God!" Alya looked at them in disgust. "What the hell?! Adrien! You're dating Lila!"

"Is that so?" Adrien asked, feigning interest. "That's funny, because I don't remember ever asking her out."

Lila was quick to summon crocodile tears. She sobbed into Alya's shoulder. "I─I can't believe you'd cheat on me!"

"Not cool, bro," Kim said.

"Didn't know you were like this, Agreste," Alix frowned.

"I─" Nino crossed his arms, looking between them. It was clear that he didn't know who to believe.

"Cheating isn't cool," Juleka muttered.

"It's not Adrien's fault," Lila said.

"Here it comes," Marinette tried not to grin.

"M-Marinette probably manipulated him into cheating on me."

"Marinette!"

"Girl! What the fuck?!"

"That's low, Marinette!"

"I can't believe you!"

"That's just wrong, Marinette."

Nino frowned in confusion. Adrien could see that he definitely doubted things now. After all, he'd known Marinette for years. He knew she would never do something like this. Even Kim and Chloé, who'd know them the longest, didn't seem to buy that.

Alya stood up. "I thought better of you, Marinette. I know that you've had a crush on Adrien for ages, but that's just wrong."

Marinette tilted her head. She looked at Adrien. "You wanna handle this, or will I?"

"I want to," Adrien said. He cleared his throat, frowning at the class. "I said yesterday that Lila and I aren't dating. What's so hard to believe about that?"

"Lila wouldn't lie!"

"She wouldn't?" Adrien asked, leaning against Mlle. Bustier's desk and putting his hands in his pockets. "Did I not tell you guys the story of how Lila lied her way into my house, forcefully kissed me, took a picture of it and sent it to every girl in my contact list? It even caused my friend to get akumatized."

"I─I─you're lying!" Alya exclaimed.

"Why would I lie?"

"Because you're cheating on Lila with Marinette!"

Adrien sighed, looking at Marinette. "Who do you think is holding the class's collective brain cell right now?"

"Hmm… Nino."

"Alright, Nino. Tell me if this makes sense. Person A tells a group of people that she is dating Person B. Person B says that they are not dating and says that he is standing at his girlfriend's side. Person B is standing at Person C's side. Person C has had a track record of claiming Person A is a liar. Person B is also dating Person C. Is there no chance of Person B and C telling the truth?"

"I… oh." Nino stared at them in shock. "How much has… Person A lied about?"

Marinette smiled. "Oh, you know, the usual. That a napkin could gouge out a person's eye, that she's somehow related to a thousand celebrities, despite the timelines not matching up, that she's also met a thousand other celebrities, despite the timelines also not matching up. That she's saved a celebrity's cat despite the fact that the celebrity never owned a cat. Despite the fact that the celebrity owns a crocodile. She's also lied about having hundreds of disabilities, and if she actually had all of them, there's a high chance that she'd be dead right now."

"I…" Nino looked at them in shock. "Oh."

"What?" Alya asked. "What is it?"

"Lila's a liar," Nino said. Marinette clapped sarcastically.

"Bravo! It only took you months to catch on!"

"Lila's not a liar!"

"Did you not hear a word Marinette just said?"

"Where's her proof?" Alya demanded.

"Where's yours?" Adrien shot back. Alya stared at him with wide eyes. "Oh, come on, Alya. You're always asking Marinette for proof. Where's the proof that Lila's telling the truth? It should be online, right? After all, considering all of the celebrities she knows, somebody would've written an article on her, right?"

"R-right." Alya swallowed, taking out her phone. "O-of course. There'll be hundreds of a-articles on her." The class seemed to collectively hold their breath as Alya opened Google. Marinette was closing the door, as she noticed Lila shifting towards it. Adrien was also closing the window, in case of an akuma.

"Well?" Adrien asked.

Alya stared at Lila in betrayal. "I─I checked fifteen different pages. The only one that mentions Lila─this Lila, not the Porn Star─is the Ladyblog."

Marinette looked at Adrien. "Did she just say that Lila shares a name with a Porn Star?"

"I think so."

Meanwhile, their class was exploding as a dozen people simultaneously screamed at Lila.

"How long do you think that will take?" Adrien muttered, trying not to grin.

"A while."

"We could leave, if you want?"

"Nah," Marinette smiled, leaning into his embrace. "I've wanted to see this for a long time."
