A/N: I like writing yuri pairings. Given, I've only done it so far with my own characters, not trying to change others to fit in or to follow an already set story line. I'm not sure how long this will be, whether it will be just a few chapters or longer, but I want to try my hardest to write something believable here, and just don't know where to end it so… Let the madness begin.

Also, I love MisaMisa. I know she's generally hated, so I'm not expecting this to be popular, but I like reviews. I just don't wanna hear Misa bashing all over, because I, at least, think she's cute ^^

Lastly, I do not own Death Note or any of the scenes/dialog borrowed from the book. Which are all through this chapter but I swear not the whole story!

Rated T for now, but probably going to jump up to M later on.

-------------------Chapter 1: A Beginning--------------------

Sayu walked up to Raito's room, surprised to find his door locked. When he let her in, she announced her problem, quadratic equations! It wasn't that Sayu couldn't figure them out by herself, because she could. It just took time and a fair amount of it for her to read over the material and play with it until she understood it. Besides, she hated math. And her brother, Raito, always understood what she was doing immediately! Even better than that was he would show her how to do it in a way that made sense and took much less time than her trying to figure it out by herself. Plus, it was more fun to solve them with him than by herself. Raito made math bearable.

Sayu's eyes widened as she picked up a dirty magazine off of the floor. Since when, she wondered, did her brother read these or take interest in girls? Maybe she didn't seem it, but Sayu liked being the only serious girl in Raito's life. And she meant that as a little sister, not as something else. Not that she wouldn't tease him for the magazine, or any other female presence. "Any dirty pictures in it?" she asked, hoping she didn't sound too hopeful as she leafed through, her eyes scanning the pages quickly. This was something she couldn't buy herself. And yet again her brother managed to impress her, reading the magazine only for the Kira/L article and not the other content. Sayu couldn't help but grin. Her brother was the best and was going to top all the world's detectives!

Sayu had managed to pass her time idly lately, mostly shopping and doing chores, but at least she was still home on time! She scowled as Raito walked in late, but her face lit up as he announced that he was out with a girlfriend and would bring her home next time. Definitely teasing material! But, behind her smile and innocent teasing, Sayu was jealous. Especially when Raito told her that she had to try harder to get a boyfriend.

"No! I'm not trying to get a boyfriend!" she immediately responded without thinking her words out first. She flushed suddenly, realizing her Mom had heard her confession. Not normal for a teenage girl. "Eh! Onii-chan, what were you doing in a hotel? Huh? Talk to me…" she hollered after him, praying her Mom would forget about her not wanting a boyfriend and focus on Raito's being in a hotel and out with a girlfriend.

Sayu sighed and walked out to the table where her mom had prepared supper. She picked at her food, realizing that she really wasn't hungry but tried to look interested in it for the sake of her mother. Her dad and brother were always out late now and she knew her mother was worrying. The least she could do was try and act normal and like everything was going to be okay. Given, that was easier without her mom asking her questions about Raito's girlfriend, claiming that surely Raito had let something slip to her.

Sayu left the table frustrated, and it took all of her willpower not to slam the door to her room when she went up there and threw herself on the bed. She was jealous. She knew it was stupid. But Raito was HER Raito, her special brother. Not some other girl's. She wanted him to herself. Who was going to help her with math if he was too busy with some other girl? Sayu flat out refused to let anyone else see her this way. She would be the perfect sister now, she would! She would be nice and sweet to whomever Raito's girlfriend was regardless of her stealing her place in Raito's life.

And, soon enough, her being nice was put to the test. Sayu, wearing her pajamas, opened the door, expecting her dad, and instead coming face to face with a blond-haired girl who wore part of her hair up in pigtails and a fashion that was a spin on Gothic Lolita. Amane Misa. That was the pretty girl's name. Sayu stared in dismay as she realized this was her brother's girlfriend, and then suddenly turned, calling for her brother. She would not be caught staring, she would not! Still, she couldn't help but stare again as her brother talked to the girl, and then as the girl walked up the stairs after Raito, flashing her panties. Something akin to jealousy burned in her chest, and this time she wasn't sure quite why. She tried to tell herself that she was just jealous that Raito had someone before she did. She wasn't jealous of this girl, no way! And yet she felt she was. She was taking her place in Raito's life, and worse she was cute! A cute that Sayu knew she could never be…

Time passed slowly as she sat downstairs at the table, working on equations that made no sense while her brother and the girl were upstairs in his room. She tried not to focus on them while at the same time wondered with a morbid fascination what exactly they were doing. She shook her head, trying to clear it. Sometimes teenage hormones downright sucked. She sighed, laying her head on top of her notebook and closing her eyes. This definitely wasn't how she planned her night.

She had planned a peaceful night, where she would finish her homework and go watch something amusing on TV while eating a small snack, something without too many calories. And then she'd go upstairs and lie down in bed and have a clear head and an easy time falling asleep. Somehow, she knew sleep wouldn't come easy tonight, not with a troubled mind.

As soon as Raito's girlfriend left she went up to take a bath. That, at least, would calm her down. She stepped into the hot water, wincing as it burnt her skin. She sat in the tub, watching the water swirl around her naked form. Her eyes wandered over her breasts, suddenly comparing them to the other girl's.

"I'm smaller," she remarked. Looking at her skin, and the traces of acne that came with teenage hormones, she scowled. The other girl was definitely prettier than her! She was willing to place bets that all of Amane Misa's was just as smooth and clear as the skin she could see on her legs, chest, and arms earlier.

Sayu dipped her head under the water, trying to let the heat clear her thoughts. It didn't matter how she looked anyways. People fell for other people because of their personality, not their skin. Surely it didn't matter how she measured up to Amane Misa on a physical side when it came to dating. Maybe Raito was right… maybe she did need a boyfriend.

She surfaced and leaned back against the tub, letting her eyes close and her mind wander, feeling the edges of sleep finally starting to come. It wouldn't kill her to let herself drift away a small bit now…

Sayu woke coughing and chocking up water, mentally cursing her stupidity. Bath tubs were definitely not a safe place for a nap!

A/N: Sorry for the slow beginning! It's short and kinda sucky, imho. Still, I needed a basis to start from and wanted to start with what was in the manga (and some of my own additions), but mainly what was seen there. From here it should pick up and get better now that I'm past necessary mostly-manga scenes (for the moment at least…) So… opinions?

I like reviews! *hint, hint*
