This is done for another challenge, 50 scenes on livejournal. This time I'll put them together in one story on here, instead of putting each segment into individual one-shots, like I did before. Each chapter is based on a given theme, but they don't necessarily connect other than with the Yusuke/Keiko subject. Genres will vary, I'll probably do some angst later on.

There will be fifty of these if I can finish! Hope you don't mind a mega dose of this pairing! XD Each chapter won't be really long though.

I don't mean to spam the Yusuke/Keiko section with my stories, I really don't. But all you readers out there should write for them if you want! Yu/Kei needs more support. :)

Ah anyway I hope you enjoy.

She had an exam tomorrow.

Of course she had studied ahead of time, going straight home after school to prepare for the test that loomed over the horizon like her own personal doomsday. The fate of her academic success dangled in the fickle hands of luck, and she hoped her keen intelligence would pull her through in the end.

So she studied and studied and studied.

Keiko stared down at the book, refusing to daydream even as her eyesight smeared the black text into one big blur.

Okay. Maybe a break wouldn't hurt.

Keiko let out a long sigh and leaned back in her chair, idly twisting the yellow knot on her uniform. She never minded extra bookwork and she studied often, but really, all this at once was exhausting.

She slid up from her seat and winced at the ache in her shoulders. Sunlight and blue sky peeked into her window and beckoned her to come outside and forget the stress of some silly test.

Unfortunately she couldn't shrug it off so easily. Her high grades hadn't earned themselves.

Keiko walked downstairs, determined to get a drink of water and nothing else. Deep as she was in goal overdrive mode, she knew her time limit and refused to become distracted.

But fate just wasn't on her side today.

Yusuke Urameshi stood at the bottom of the staircase, scruffy as always with his bruised face and slicked black hair. His lips inched upwards into a devious grin when she met his gaze.

"Don't you have anything better to do then lock yourself up and read those stupid textbooks?" he said. "You're gonna pass the test, you always do, damn."

She scowled at his mocking tone. "Don't you have anything better to do then harass me?" she fussed. "What're you doing here anyway?"

"Oh that's not harassment." His smirk grew. "Harassment is more like-"

"If you grope me I swear…." she crossed her arms. "I'm not in the mood for your crap today."

"You're never in the mood for anything." He rolled his eyes then proceeded to stick his tongue out at her, something he hadn't done in ages. "Except for schoool, like the teacher's pet you are!"

"Better than a delinquent!"

He scoffed. "Whatever you say. Delinquents have more fun."

He was being awfully cheeky. Keiko wondered if he had just won a fight with some rowdy thug. That was usually the case when he came around all beat up and cheerful, like a big bad allycat who had defended his turf.

Yusuke crossed his arms, mimicking Keiko's body posture. Her curious look gave him the urge to fidget; her thoughts were obviously on him and he had no idea what she was thinking. It made him slightly uncomfortable. Not that he'd ever let her know that, though.

Her expression switched to one of concern. "Do you need some help? Your face is bleeding." She had bought a brand new first aid kit for one reason: Yusuke. He never admitted his injuries, but she could always drag him upstairs and clean up his cuts and bruises whether he liked it or not.

He rolled his eyes again. "I'm fine, mother."

"Shut up!" she snapped. After a moment she added: "And I wouldn't be your mother for all the world, by the way. The mere thought of living with you gives me a headache."

He made a twisted face. "I wouldn't wanna live with you either, that's pretty gross. But…" he smirked, a devilish glint in his eyes. "Maybe then I could get under that skirt of yours!"

"THAT'S IT!"

Keiko let out a frustrated shriek.

And Yusuke ran for his life, laughing as flying objects whizzed past his head.

Keiko forgot all about the exam.
