Beginning Note: So, apparently I've been really into writing Rurouni Kenshin stories again. Not really sure why. I think it's because I re-read Broken Pieces by linay. But, regardless of the reason, I'm glad I am, though they seem to be getting somewhat violent. This is the first part of the Bad Romance series that popped into my head. Yes, the title is based off of the Lady Gaga song "Bad Romance" and each part is based of part of the lyrics. None of these stories are connected. Some will be AU, others part of the RK world. Please enjoy.

Disclaimer: I don't own the RuroKen characters… I just screwed them up for my own sick purposes. They belong to Watsuki Nobahiro.

I Want Your Disease

"Kenshin!" cried the raven-haired girl tearfully, whimpering in pain. "Please, that hurts!"

The former assassin's grip tightened on her delicate wrist, bruising the pale flesh. He dragged her along the dusty street, anger fizzing comfortably under his breastbone.

"Kenshin!" the girl cried again, this time eliciting a response out of the normally gentle man.

"Don't call me that," the redhead growled, shaking her roughly, like a terrier shakes a rat.

"It's your name," she said stubbornly through her tears. "And that's what I'll call you."

She found herself being spun into the plank wall of someone's house, head framed by two muscular arms. Tear-filled azure eyes met angry golden amber.

"I said not to call me Kenshin, Kaoru," the man warned.

Kaoru stuck her chin out mulishly despite the occasional silver tear sliding down her face. His molten eyes narrowed and he frowned, tiny lines appearing at the corners of his mouth and eyes, showing his true age.

"I said to stay put," he snapped, hitting the wood beside her head for emphasis.

"I'm capable of handling myself, Battousai," the kendo teacher bit out, sneering a little.

"Yeah, you did a fantastic job before," Kenshin shot back. "Let's see. A bloody lip, bruises, a black eye… You're right. You did a great job of taking care of yourself. If I hadn't shown up when I did, you'd be way worse."

The teenager gave a humorless laugh.

"My hero," she said sarcastically, tone filled with venom. "I've been taking care of myself years before you appeared. What makes you think you can act like my father?"

She spat at his feet.

"You're a damn hypocrite. You're far from the person you were when you first came to the dojo. What happened?"

"He got lost," the redhead said shortly, clenching his fists until his knuckles were white. "Deal with it."

Angry, she spit in his face.

"You disgust me with what you've become," she raged, desperately missing the Kenshin that she loved.

She cringed and closed her eyes tightly as she saw Kenshin's hand fly towards her face. Kaoru braced herself for the sting of flesh against flesh. It never came. The dark-haired girl opened her blue eyes. Kenshin's hand was stopped inches from her cheek. Instead, he grabbed her chin, forcing her to look at him. He was staring at her, an indescribable emotion flashing in his eyes.

"Your stubbornness will get you killed," the former killer told her softly, fingers tightening painfully on her fragile jaw. "I can't live with that, Kaoru. Do you understand that?"

Mesmerized by his gaze, the young woman nodded.

"I would never hurt you," he reassured her, stroking her tangled hair with his other hand. "I never want to hurt you."

He swallowed the lump in his throat.

"I have a disease. It's something I can't help."

"Disease?" Kaoru echoed faintly.

"Yes."

"Are you sick?" she asked in a moment of unintelligence.

"In ways," Kenshin muttered. "It's a disease that turns me into this. This monster."

"I don't understand," the teenager said, brow furrowed.

"It's not something Gensai or Megumi can treat. It's a result from years of dancing with insanity. It's chaos."

"Chaos?"

Kenshin cupped Kaoru's face with strong, calloused hands.

"Chaos," he affirmed. "It grips me in moments like a vice. Like before, when you were in danger. I become this."

"I want to understand."

"What do you think-"

"No," the girl said, cutting him off, no longer angry with the man. "I want to understand. I want you to share the burden."

"Kaoru, no," Kenshin said alarmed, worry lighting his amber eyes.

"Yes, Kenshin."

He flinched at the name and her tone.

"I want to understand your pain and your reasons. I want you to show me chaos."

"I can't le–"

"I'm not asking, I'm demanding."

The inflicted man took in her appearance. The dusty and torn state of her once fine kimono, the messy raven tresses, the forming black eye, and her bloody lip. Perhaps she could understand his burden and bear some of it. He just prayed to God it wouldn't break her.

As he lowered his lips to her, he whispered something into her ear.

Welcome to chaos.
