A/N: This AU has extreme cussing, violence, and other vulgar things for general and mature readers. Marinette has no miraculous but Cat Blanc is rouge vigilante. Beware: Obsessive/yandere Adrien or Cat Blanc.

Marinette had a normal, shitty life where she was yelled at by her best friends Alya and Nino who were arguing over music artists. Kim, the football team captain, fumbled on top of their lunch table. Marinette got angry and grabbed his football and threw it in Kim's direction,, but instead, it hit a blonde boy's face.

"What in hell? Who the fuck hit me?" Adrien yelled, Kim was the one to dread because Marinette left the scene quickly.

A few minutes later, one of Adrien's bodyguards grabbed Marinette by her waist; not hesitating to place her in the passenger seat, she immediately realized Adrien was in the driver's seat; his entire gang members were inside the car, too.

"I knew it was you who threw that football because Kim told me everything, anything he knew about you. I made him spill the truth, so I decided to choose you to be my girlfriend or wife, M'lady," Adrien smirked evilly, leaning over into her ear.

"No way! There's no way I'm going to be yours at all. I'd rather date Luka or Nathaniel before even saying, "I do"!" Marinette sarcastically retorted, opening the car door to leave.

"Leave me the fuck alone!" Marinette yelled, slapping Adrien very hard.

Marinette ran for her life as Adrien Agreste, an infamous gang leader, ran after her; she was cornered by him and his gang members, who were watching Adrien push her into a wall. She wasn't ready for a relationship with a gang leader, even when he was around her age.

"Why are you running away? I only want you, princess. You're mine," Adrien said, sending his gang members and bodyguard after her.

"Stop, please let me go! I'm not yours, I never will be," Marinette yelled, Adrien and his gang mocked her as she felt small to them.

Adrien got pissed and with his fingers snapped, his gang members left the two by themselves.

"You ungrateful bitch, you slapped me! I would like it if you do that to me again, princess," Adrien smirked, his nose bleeding heavily on his shirt as he pushed Marinette into a wall with full force.

"You're a freak! Why do you want me to slap you more when I only slapped you to get away from you, you asshole?" Marinette asked, kicking him in his stomach as he almost threw up his lunch.

"Cause I'm in love with your strength and courage," Adrien said, leaning towards her as he dragged her by the arm to his mansion.

Her phone beeped with news about Cat Blanc or something as soon as he sat Marinette down, and she decided to watch the video instead of ignoring the news.

"Cat Blanc has done it again! He kills police officers and normal civilians; best advice: never come at night when you walk outside," the news reports before shutting off completely.

Adrien looked at her as she shook in fear and then spaced out in her thoughts. Chloe knocked on the door, he opened it and she reacted the same as often.

"Adrikins, who's this? I thought I was yours!" Chloe yells, fake crying before running away to get to her father.

"Don't worry about her, princess; you're the only one I have my eyes on," Adrien said, tying Marinette to a chair while she struggled.

"Why are you tying me up?" Marinette asked; Adrien ignored her, running to the restroom.

"Plagg claws out," Adrien transformed into Cat Blanc, the infamous vigilante.

He pretended to jump out of the window, and Marinette was surprised by the mystery guy. Marinette never heard of Cat Blanc, so she was intrigued by him instead of running away.

"Hey Marinette," Cat Blanc greeted, freeing her from the ropes he tied her up with.

"How do you know my name? You're cute by the way," Marinette asked, playing with his bell as Cat Blanc tried to control himself.

"I know everything about you, that's all I can say," Cat Blanc said, his blue eyes piercing through hers.

This was shocking and interesting to Adrien because he fell for Marinette but she liked Cat Blanc more.

"Well then, what's your name?" Marinette asked poking his chest.

"Cat Blanc, you can call me Chat or Kitty," Cat Blanc said, purring as he nuzzled his nose into my neck.

"You can call me Mari," Marinette said, petting his head.

The two teenagers talked about their interests, favorite subjects, and everything in between; Adrien couldn't get any more excited.

"Marinette, girl! You've staring into space for a while since we started class. Is there someone you're thinking about?" Alya asked, waving her hand in her face.

"Yes, this time it's not Nathaniel or Luka; it's someone I don't know much about," Marinette said; her eyes were hearts, but her friend was confused.

"What's his name?" Alya asked, Marinette replied with a lovesick grin.

"Cat Blanc," Marinette answered, catching everyone off guard with the name she said.

"Is there anything wrong?" Marinette said, confused as Alya told her.

"He's a vigilante who kills people, criminals, to be specific. The way he kills them is scary," Alya said, Marinette immediately knew what she meant.

"He's a hero, is that what you're saying?" Marinette asked, everyone went silent and just nodded their heads.

"We don't know exactly yet but that could be the main identity of his status," Alya shrugged her shoulders, standing up to go to class.

Marinette was eating her lunch, but a hand grabbed her shoulder, and she turned around to see Adrien Agreste; she instantly lost interest by throwing away her tray.

"Where are you going, princess?" Adrien asked; Marinette ignored him and walked past him to her next class.

"Hey Nathaniel, how was your art class?" Marinette asked, Adrien was jealous as Nathaniel answered her question.

"Well, it was nice, but the teacher was just treating his students like shitty junk," Nathaniel said, walking away as he saw Luka look at him.

"See you later, Nathaniel!" Marinette said, waving goodbye as she noticed Adrien behind her.

"How can he make you smile when I can't?" Adrien smoked a cigarette, throwing it away as Marinette walked off but was blocked by his gang members.

"Why can't I live a normal life when you're around?" Marinette sarcastically retorted, folding her arms.

Adrien turned her head to look at him. She kept pulling away, but he was strong.

"Because you're mine, not Nathaniel's," Adrien said, kissing her cheek.

"He's gay. I rejected him a long time ago, he's already over me," Marinette said, slapping his hand away.

"But princess, you're his friend. And that's hard for him to move on when he's around you," Adrien teased, Marinette's cheeks flushed in embarrassment.

"That's why I didn't like him like that. He was always my friend, nothing more- mmph!" Marinette said Adrien interrupted her with a kiss on her lips.

He kissed her very passionately, wrapping his arms around her waist. She tried to push him off, but he slipped his tongue in her mouth; he broke the kiss as Marinette looked at him in horror and complete disgust.

"Is that Adrien? Why the hell did he kiss her?" Nino asked, other students started to whisper to one another as rumors slowly spread.

Adrien pushed her to the wall, making her feel uncomfortable as students and teachers left the hallway. He kissed her neck, making her squirm but Nino interrupted him.

"Ahem! Can't you see she's uncomfortable, dude?" Nino snaps him into reality.

"If you weren't careful, you would end up getting her hurt," Nino added, grabbing Adrien off Marinette.

"But," Adrien said, Nino just cut him off.

"Be more careful, her dad can be protective over her," Nino said, recalling the last time he remembered that her father was scary.

"Fine. I'll try to be a little more considerate," Adrien said, getting off Marinette who was frozen in fear.

"You made her scared in shock. Now I'll have to get squished by her dad because of your wild behavior and because I have to watch after you," Nino complained; Adrien went to the restroom to wash his face.

"Was I being pushy or was I too clingy?" Adrien asked himself before walking out of the bathroom.

The rest of the school day, Marinette couldn't be near Adrien for a while. For the time being, Adrien sulked, and Marinette enjoyed her freedom while she could.

"Adrien, since you are still acting wild lately... You're to learn to be more gentle and to teach you how, you're going to attend every class with that girl until you learn how to behave," Natalie, his dead father's assistant, assigned before she left the hallway.
