Blue Moon

Author's Note: Hey guys! This is my first Death Note fic, and it's Light/Sayu. It probably won't be the best, and it's most likely VERY OOC, but I have only read up to volume 7 in the manga. I have the other volumes on hold at the library. Thank god for MangaVolume! I just thought that this was a perfect song for the couple. Of course, before I saw the lyrics, I thought that the line was "Oh what a beautiful lie". Anyways, I hope that you like it, and constructive criticism and flames (if they are nice and kind, and not harsh) are welcome.

Disclaimer: I don't own Death Note, Light, Sayu, or any other characters. Blue Moon belongs to Anna Tsuchiya. All I own is the plot...hopefully.

Blue Moon

It's so dark, it's so cold

No hate, no tears,

No time for us, nobody else

Just me & you

Ah, it's so sad, it's so deep

In silence, on the wave, in the light,

Gently dancing with me

Sayu Yagami took a couple of deep breaths to calm herself before knocking lightly on her older brother Light's door.

He said, "Yes, what is it?" as he opened the door slightly.

Sayu held up her algebra book and said, "Could you help me with my algebra, please?" She hoped that she wasn't blushing.

He laughed and said, "Sure." He opened the door completely.

She walked in and went over to his desk, where he usually helped her. He closed the door, and she pulled up a chair as he sat down beside her. She looked at Light out of the corner of her eyes as he leaned over her book and asked her what she didn't understand.

She pointed out the homework problems, and he started explaining. She listened with half an ear, thinking to herself. She knew that she shouldn't be feeling the way that she was feeling, especially towards her brother. She inhaled his scent, smiling. She couldn't help but stare at him. His buttoned down shirt was open slightly, and his jeans were just tight enough. She looked away when she realized that she had been staring at him for too long. But she couldn't help but wonder what it would be like to kiss him. Stop it, Sayu, she thought. This is your brother you're thinking about! You know that it's not allowed!

She was, however, brought back to earth when Light asked her, "Do you understand so far? Can I keep going? Or do you need me to explain part of it again?"

She said, "You can keep going. I think that I'm starting to understand it better, though."

Light smiled and said, "Good. Now, for this next part, you need to..."

He trailed off when he noticed that she had her eyes closed. "Hey, am I really that boring?" He laughed when her eyes popped open.

"What? No, you're not boring at all! I'm just ...thinking about someone." She said, hoping that he would stop asking about it.

"Is he—I'm assuming it's a boy—the reason that you've so distracted lately?" Light asked her, amused.

"Eh? Oh, yes, it's a boy, and yes, he's the reason. Wait, how do you know that I've been distracted lately?" she asked him, suddenly suspicious.

Light laughed again. "Really, Sayu, I can read you like a book. Is he anyone I know?" He stared at her, waiting for an answer.

"Yes, he is. As a matter of fact, you know him very well." Sayu said. She realized what she had just said, and quickly added, "But don't ask me any more questions!"

"What, I can't even guess?" Light replied. When Sayu shook her head, he sighed and said, "Then why don't you just tell me? If I know him so well, I can tell him...unless you don't want him to know."

Sayu shook her head again and said, "No, I just can't tell you! Especially because..." she trailed off, not wanting to finish.

"Because what, Sayu?" Light asked, curious. Why wouldn't she want to tell me? It's not like I would make fun of her for it, no matter who the guy was!

He heard her mumble something, and he took her head and turned it to him. "I'm sorry, I didn't catch that. But, you know you can trust me!"

Sayu sighed, and thought, Well, here goes. "Because it's YOU!" she said. She ran out of his room, not waiting to see what his reaction was.

She ran into her room and closed the door. Then she walked over to her bed and jumped onto it. I can't believe that I just said that! Now it's going to be so awkward whenever we see each other at home, or anywhere else!

Light sat there, unmoving. It's me? He thought, stunned. I never would have thought! For once, he didn't know what to do. He started to get up to talk to her, when he noticed that she had left her algebra book on the desk. He picked it up, and brought it with him.

Sayu was laying on her bed with her eyes closed, trying to forget what had just happened, when she heard a knock on her door. "Who is it?" she called, already knowing who it was.

"It's me, Sayu. Can we talk?" came Light's voice through the door.

Sayu said, "Don't come in!" Light was the last person that she needed to see after what she had just told him.

Light sighed, and walked in. "You left your algebra book in my room." He put it on her bed as he sat down beside her.

"Were you serious when you said that the person you liked was me?" He asked her, pulling her up so that she was sitting on the bed, rather than laying on it.

"Of course I was! Why would I lie about that?" She said, starting to cry. "I know that it's wrong to feel this way about you, but I can't help it! You must hate me for it! Go ahead and hit me, yell at me, do whatever you want! I wish that I could wish my feelings away, but i can't! You don't know what I'm going through!"

Sayu finished blurting out her feelings, and looked at Light, who was sitting there with an unreadable expression on his face. "Well, don't just sit there! Say something!"

Light was silent for a moment, and said, "Actually I do know how you feel. I'm glad that you told me, Sayu."

She looked at him, confused. What was he talking about?

Suddenly, Light leaned over and kissed her. She was shocked, to be sure, and didn't know what to do. She started to kiss him back, not sure that she wasn't dreaming. The fact that her brother was kissing her never crossed her mind. His hand slowly went up her arm, and she shivered. He smirked and began kissing her neck.

When he pulled away, she reached for him again, but he stayed out of reach. He put a finger to his lips and said, "Well, I'm glad you understand it now, Sayu. If you need any more help, just let me know."

Sayu was confused, until Light opened her door and saw her mother standing there. "It's almost time for dinner, you two."

They nodded, and, after looking at Sayu and smiling slightly, Light went downstairs.

Sayu sighed happily. She knew that what they had just done was wrong, but it felt so right. How was that even possible. She smiled as she followed Light downstairs.

When the sunlight came into my room

Forget about the time for crying

I don't have to weep day & night no more

Oh what a beautiful night

Save me from shadow in my side

Oh my blue moon

It's the first time to meet

Somebody like you

In my life time

You are my blue moon

Oh, you are my blue moon

From that day on, Sayu and Light always had a relationship when he was helping her with her homework. To their parents, they were just brother and sister. But to themselves, they were lovers. He always knew just what to say to make her laugh, but she couldn't help thinking that it was too good to be true. Then the whole Kira thing started, and they were spending less and less time together, which was strange, since they lived in the same house.

You make me smile and make me laugh

I know you are my little angel

When you kiss me, I know this is color of love

I want to be the air for you

I want to be tears for you

I will wipe away your tears

If you feel alone

When Light had brought home Misa, his "girlfriend", Sayu had been shocked, but had covered it up. When Misa wasn't there, Light promised Sayu that he would explain the situation to her sometime. But he never did.

She may not have been as smart as Light, but Sayu knew when he was lying about something. She noticed that he had been acting different since the Kira case had started, but she couldn't figure out why. She wanted to see him again; she missed their "homework" sessions.

Oh what a beautiful night

Save me from shadow in my side

Oh my blue moon

It's the first time to meet

Somebody like you

In my life time

You are my blue moon

Oh, you are my blue moon

Now, twenty years later, she still remembered the night when she and her mother found out that Light was dead. It was hard enough to lose her father, but Light...Sayu ran up to her room when she heard about him, and lay on her bed, crying. Why now? She thought. Why did it have to be so soon after dad had died?

She didn't know how or why he had died, but she knew that she had to move on. Now, she was married to a good man, Daniel, and had three kids, Light, Mike, and Kingone. But she couldn't help but think every so often about what life might have been like if Light hadn't died.

I want to be the air for you

I want to be tears for you

I will wipe away your tears

If you feel alone

Oh what a beautiful night

Save me from shadow in my side

Oh my blue moon

It's the first time to meet

Somebody like you

In my life time

You are my blue moon

Oh, you are my blue moon

Promise me, if I get lost on my way

And don't know where to go

Show me the way, Show me the truth,

Guard me with your arms, forever.

FIN
