Adrien has never actually looked into Marinette's eyes; not like he is now.
After a year, the cat-themed superhero realized that his attempts to woo his lady were futile and decided to get over her- this led him to Marinette. She was always so sweet and caring; so nice and charming. The more time he spent with her, the more Adrien realized that his crush was more than a crush.
The day he decided to take action was a day similar to the one where they became friends; the same day he and Ladybug defeated their first akuma. It was raining harshly, the thunder booming outside their classroom windows. It was right before their first class, just has he, Nino, Alya, and Marinette were about to enter the classroom. Adrien grabbed the young designer's wrists, carefully looking into her eyes. That wasn't when he noticed it, however.
"Can I talk to you for a sec?" He asked, hoping Nino and Alya would get the hint. They did and quickly went into the room.
"What is it, Adrien?" She asked. Marinette's stutter and nervousness disappeared over time, once getting to know Adrien for the absolute dork that he really is. Adrien grabbed her hands and gazed into her eyes. Eyes that seem so familiar. Almost too familiar.
"Would you…" He began, leaning closer to look into her eyes. He squinted, before letting his mouth open again. "Ladybug?" Marinette sharply breathed in, tearing her hands away.
"How did you know?!" She cried. Adrien groaned and rubbed his hand over his face dramatically.
"Goddamnit, Mari, I fell for you twice!" He groaned again, before lighting up and laughing. He took her into his arms and spun her around. "I fell for you twice! Well, I fell the first time. I walked right into your direction when I took an interest in Marinette! You are so purrfect, milady." Adrien nuzzled into her neck and purred, smiling.
Marinette gasped, her own eyes shaky. "Chat?!" She whispered, gasping. Adrien pulled away before taking a hand in his and kissing it gently.
"In the flesh." Adrien braced himself to be pushed away, but nothing came. Instead, a sniffle was heard. "Princess?" Adrien got up from his bow, to see Marinette crying. "Oh…" She probably hates me now, way to go, loser. The voice in the back of his mind said; it was the same one who told him that he was the reason his mother left. "I'll go, now…" Adrien began to head in the direction of the classroom when Marinette grabbed his arm and pressed her lips to his.
It lasted a few moments and Adrien pulled away first. He looked at her questioningly and Marinette sighed. "I fell for you twice, too, mon chaton. First you as Adrien and then you as Chat. I felt so bad for liking two boys at once, but that just meant that I fell in love with you twice! I never stopped loving Adrien and then I fell in love with Chat and I felt like such a bad person for liking two guys at the same time!" She pulled him into a tight hug and buried her head in his shoulder. "Goddamnit, I love you so much, you stupid cat." Adrien hugged her back, grinning as he did. He felt her smile into him and hug tighter.
"I love you, too, Purrincess." Marinette stiffened and broke from him and entered the classroom.
"Nope. Whatever we had, it's over. Your puns are horrible."
"Mariiii~" Adrien whined, following her. He pouted and caught up to the dark haired girl. He wrapped his hands around her waist and pulled her close, resting his chin on her head.
"Let go, you dork!" Marinette cried, playfully thrashing.
"Meow." She elbowed his ribs, hard. "Meow-ch! That hurt, Princess." She finally escaped his grasp and looked at his pouting face. Marinette cupped his face and pulled him down for a quick kiss, successfully turning the pout into a smile.
Alya let out a strange noise. Nino was looking at them with an amused smile. Chloe sighed, confusing Marinette for a moment. Kim smirked. "So when did this happen?" The Vietnamese boy asked in an amused tone.
"I, uhh, Mari, you tell them." Adrien said, blushing. He bent down and nuzzled his head into the crook of her neck.
"Adrien and I roleplay. Live Action Roleplay. He has a thing for my character and mine for him, as in Adrien, not his character, but he got over that one and wanted to talk to me, Marinette, about something. I don't know how, but he recognized me. Not complaining, but how, Kitty?" Marinette had sometime lifted his face up and looked at him with an eyebrow raised.
He cupped her face and his blush faded. "I'd recognize these big, bluebell eyes anywhere. Mask or no. I've just never gotten lost in Marinette's like I did with your… Character's." Adrien stroked her cheeks with his thumbs and most of the girls in the class awwed. Marinette giggled and pushed him away.
"You are a hopeless romantic."
"Only when it comes to you, milady."
"So what did you roleplay as?" Ayla asked, barely forming the words because the only thought in her head was Holy shit the only thing that could make this day better is Ladynoir.
"Well, my dear Marinette was Princess Malina of a land far, far away and I was her knight in shining lea-armor." No one, save for Marinette, noticed his slip-up. She giggled.
"In our little group, we had our mentors. I forgot the name of Dark Knight's- I mean Adrien's- mentor, but mine was a pixie named Tikki. She is so cute and she lives off of cookies and sweets. How she isn't fat, I have no idea." Marinette patted her purse, and got poked in the hip by her kwami.
"Mine was a pixie named Plagg. His life-force is cheese." Adrien looked to Nino. "He's why I always smell like it. And Plagg's a total dork. If he were an animal he would be a cat. I mean, he's even sat in boxes when we have them. It's so annoying because he even eats catfood sometimes. It shouldn't be healthy. I swear-"
"Mon minou, stop." Marinette pressed a finger to his lips and smiled. She turned to Chloe. "Just curious, what was that smile for?"
The rich girl laughed. "I was honestly really worried. I thought Adrien was gay and I didn't want any girls to make any advances on him."
Alya blinked. "Wow… I don't know if that's considerate or not."
"Thank you for your concern, but I'm straight as Nath's hair." Adrien said, smiling.
"No, you're not. I remember, sometime before you started school, you were saying how you would totally go gay for Chris Evans. I would totally go straight for him, not gonna lie." Chloe laughed, examining her nails. The blonde lit up and gasped. "I don't need to act straight, anymore! Wait, but Adrien!"
"What, Chlo?"
"Marinette was the girl I told you about a few years ago."
"The one you had a crush on and asked me for advice?"
"Yeah. Your advice sucked. You said to follow my heart. My heart said to be a fucking dick to the girl I think is literally the best person on Earth. And Marinette hasn't even been akumatized, she is a goddess and a saint." Chloe sank in to her seat. "Anyway, I was thinking that if I could keep Marinette away from Adrien long enough, Marinette would get over him and then be all sad and then I could go comfort her and bam she falls in love with me. Then we would have two, no, three kids, a cat, a dog, and a hamster!" Chloe looked into the distance with dreamy eyes. She soon came to her senses and blushed deeply. "Shit." She shrugged, the blush leaving her face. "Oh, well. You're with Adrien. My two most favorite people on the world are a couple. I wanna be a groom's woman, I'll be waiting. I understand if I'm not the best woman, I've been a real bitch lately."
Marinette stared with a slack jaw and was about to retort, but Mme Bustier entered the room. "Okay, class, time to start learning." Most of the students groaned, all going back to their respective seats. "You can finish your conversations during lunch."
They did and then everyone realized that Chloe is a terrible flirt. and that she's a weeb like adrien but PLOT TWIST she got adrien into anime.
