Marinette
Marinette sipped her hot chocolate, still trying to figure out how she ended up in this situation. She was alone in the kitchen, sitting at the island waiting for Adrien to let her know if he could find clothes her size. It was all happening too fast for her. One minute she could barely talk while showing him his homework, the next minute she was taunting him while playing video games. Now they were snowed in with only one other person in the vast building. The warmth of the hot chocolate did little to comfort her.
She was considering transforming and risking the cold weather to get home when her phone buzzed. Alya was requesting a FaceTime chat. Marinette smiled and picked up the call. She was greeted by what appeared to be an extremely pleased Alya with a smiling Nino. "Hey, guys!"
"Hey guys? You are trapped with the love of your life and all you can say is hey guys? Giiiiiiiirrrrrl give me some deets! Where are you sleeping? Is it just the two of you? Nino says that Adrien said that his father is out of the city so at least you don't have to deal with that buzzkill." Finally, Alya stopped to take in the look on Marinette's face. "Girl, you okay? You seem a little pale."
"I'm fine, just fainted earlier after I got the news and I might still be freaking out about this whole thing."
"Dude, you fainted?"
Marinette frowned, confused by them. When they first called she had assumed they had talked to Adrien beforehand. "Yeah, didn't Adrien tell you?"
Alya shook her head, grinning as if she knew something Marinette didn't. "Girl, we never talked to Adrien." Nino caught on and nodded his head, his smile growing wider.
Marinette narrowed her eyes, asking them, "Then how did you find out that I was stuck here with Adrien?"
Alya did her best to contain her laughter, while Nino decided to tell her what was up. "Dudette, you might wanna check Instagram." Marinette frowned and switched to her Instagram. What she saw made her freeze. Adrien had taken a selfie of the two of them before leaving to search for extra clothes, referring to her as good company in the caption. His smile was huge, his eyes shining brightly as he held his mug in his free hand. Clearly visible behind him, Marinette sat at the counter sipping her hot chocolate, face red with embarrassment. The post had over a million likes already and the number only seemed to climb up. Marinette groaned, dropping her phone on the counter as she dropped her face into her hands.
"Girl, at least read the comments before you try to hide." Marinette sighed and picked her phone back up, dreading to read the responses.
#1AAfan: so adorable! Hope you guys will ok!
i3AAxoxo: she is soooooo lucky! I would melt if I was in her shoes
: please keep sending updates! Or else...
FutureMrsAgreste: hmmm… how do I change my twitter username? Also isn't that his designer friend?
UnderAgreste: better than that Lila chick he shoots with sometimes, that girl is creepy AF
MySunshineBoi: OMG! Did you guys see the tag with the photo of him and her sleeping on the train? So cute! I need more! 333
To her surprise, all the comments seemed to be positive towards her. Some offered encouragement, others demanding for more information or daily updates. There was the odd hater, the most prominent one being ladyAgreste who made multiple remarks about how Marinette planned the whole thing to get some alone time with Adrien.
Despite the fangirl's accusations, Marinette still had a smile on her face when she switched back to facetime with Alya. "Okay, maybe it isn't that bad." She frowned when she saw Nino wasn't next to Alya anymore. "Where's Nino?"
"He had to take a call," Alya told her, shrugging. "So, still feeling insecure about being alone with Adrien or are you good now?"
Marinette hesitated, then nodded her head. "Yeah, I feel a bit better thanks."
Alya's smile switched to a smirk. "So are you two going to share a bed?" Marinette groaned, knowing lots of these questions were gonna happen. As Alya attacked her with embarrassing questions, Marinette studied the oven, a plan forming in her mind.
Adrien
"I don't know, Nino. Marinette always seemed so uncomfortable around me, especially after that prank I pulled in the museum. And just as she was just starting to relax around me, the walls go back up. What do I do?"
Nino nodded on the screen as Adrien set down the only two sets of clothes he could find close to Marinette's size on his bed. He planned to let her take his bed while he slept on his couch. "Just be yourself. Pun, laugh, be a nerd. Marinette will open up if you stop being so nervous around her. And no pranks! Alya is still mad about the museum, by the way."
Adrien groaned as his greatest mess-up with Marinette was brought up. She was on the verge of tears after and he felt something 'off' about the way she told him she was playing a prank on him. "I'm never gonna live that down, am I?"
"Maybe this is your chance to make it better. But what's the plan? Does she even have extra clothes? Where is she sleeping?"
"I don't have much of a plan. I'm gonna offer to let her take my bed while I sleep on the couch. As for clothes, I could only find these." Adrien held up the two onesies, one Ladybug themed and the other Chat Noir. He had bought them as a set when the hero themed merch first came out.
Nino laughed his head off. "Please tell me you aren't gonna try roleplaying on the first night."
Adrien blushed, "No! Why would I do that? That would scare her out of the house!"
Nino kept laughing as Alya joined him in the call, "Hey, Adrien. You gonna tell that girl your master plan or will she have enough time to spiral again?"
"Adrien here, is going to offer her his bed and Ladybug onesie," Nino eagerly informed his girlfriend who's jaw dropped as she looked back at Adrien.
"There is a Chat Noir one too, I'm not forcing the choice on her!" Adrien responded a little too quickly.
Alya raised an eyebrow, sensing something interesting. "Why so defensive? Are you nervous?"
Adrien sighed heavily and admitted, "This is the first time I'm ever having a friend sleepover."
Nino frowned then nodded as if he perfectly understood while Alya's mouth dropped open . Which he did, since no one else had a lower opinion of Adrien's father than Nino. He saw the man as the enemy of fun. "Dude, there is nothing to worry about."
"Yeah," Alya joined in., "Everyone has a first sleepover. Normally they are planned in advance but this isn't that different."
"But it's with Marinette!" Adrien exclaimed as if it explained everything.
Alya rolled her eyes. "Just be yourself and make sure you do nothing weird. Oh, start with a movie! And make popcorn with lots of melted butter! Marinette loves watching movies with that and would be really happy. Then it removes all chances for you to bumble things up like when she confessed to you at the museum and you broke her heart in the car." Alya's teasing smile fell as she realized what she just said.
Nino jumped in to do damage control, saying, "Yeah, the whole confession prank because she knew you were pretending to a statue. Oh, look at that! The movie we are going to watch next is going to start. Bye." Nino hung up the phone as Alya started sputtering out gibberish.
Adrien sat down on his bed and stared at the blank screen. Plagg hopped down from his hiding place. "What was that all about, kid?"
Did they know something about the day at the museum that he didn't? "Something is up, Plagg. Was Marinette really pranking me that day?" Adrien slowly inched closer and closer to the truth, Plagg's eyes widening at the sight of the end of all his problems. "What if Marinette.." Adrien shook his head, it sounded crazy in his head and would be worse when he said it. It didn't make sense, but at the same it did?
"Spit it out!" Plagg hissed.
I think that Marinette likes…" Adrien frowned going back into his thoughts.
Plagg hissed, if this kid won't get it out, he was going to cataclysm his secret closet of Ladybug merch. "Spit it out!"
Adrien looked at the kwami with a serious expression on his face."Marinette likes to prank a lot?" And with that, Plagg and the invisible audience died from whiplash due to the sudden halt in progress. Adrienette will have to wait because Marinette is a very good friend who likes pranks. Kill me.
After murdering the audience with his obliviousness, Adrien headed back to the kitchen as he texted Natalie again asking for help on the clothes situation. Marinette was eyeing the rest of the kitchen curiously, giving herself a tour while she waited for him to return. "Sorry for taking so long. I tried calling Natalie and my father, but neither of them picked up the phone." He rubbed the back of his head as Marinette gave him an understanding smile.
"Don't worry, Adrien, there is no need to be stressed out about everything." She flashed him a small reassuring smile. "Sorry if I freaked out earlier, it was just a lot to take in. One second we're playing video games, the next we are locked in together in this," she gestured around them at the mansion, "giant house and to be honest, this place is most likely haunted."
Adrien frowned, not at all sure if she was joking. "Uh, I'm pretty sure it's not haunted. Otherwise, the ghosts would have attacked by now."
"Naw, your father is too salty for them to risk it," Marinette said, a smirk starting to form on her face. Adrien burst out laughing, causing Marinette to laugh as well. When they finally stopped, she gestured to the oven. Adrien looked at it and realized that it was on and something was cooking inside that smelled good. "I hope you don't mind, but I ma-made a pizza while you were gone. I figured we-we need to eat dinner still."
Adrien sniffed the air, it smelt good. "What is it?"
"It's a popular pizza called Reine. It has ham and mushrooms, though I added some pepperoni." Adrien grinned in excitement as she turned away to inspect the progress of the pizza, opening the door to do so. When she opened the door, Adrien could smell the wave of aroma. He frowned, something smelt familiar about the pizza. "And I couldn't find mozzarella so I used camembert instead. Sorry if that's an issue," she apologized, her back still turned to him.
Adrien froze as his face turned white, panicking inside his mind. What if Plagg flies out thinking with his stomach? What if Marinette discovered his secret identity? What if she didn't want to be Chat Noir's friend anymore? What would he do if she doesn't give him food anymore? What if…
"Pizza's re-ready!" Marinette declared, pulling it out of the oven and placing on the hot plates she set out. Adrien could only smell the camembert, thinking of Plagg phasing through the wall and crashing into the pizza. Marinette cut the pizza up into eight slices and put a slice on a plate for him. Marinette noticed his hesitation and gave him a comforting, confident smile. "Don't worry, this will taste like per-erfection." She mentally hit herself, realizing what she said sounded like purrfection. At least Chat Noir will never know that she accidentally made a cat pun, right?
Adrien fainted.
Bonus Scene:
Tikki struggled to hold Plagg back. "Plagg, no! You can't expose us or they will figure out each others' identities!"
"Need. To. Eat. Camembert pizza!" Plagg struggled against Tikki's hold, the smell overwhelming him.
"Your chosen is literally unconscious on the ground and that is what you are worried about?"
"Camembert!"
