There are two times when I typed L's real name, those two times are in spoiler tags. If you don't know and don't want to know, you have been warned.

Haruka watched in horror as L fell from his chair. this couldn't be happening. She couldn't believe what she was seeing, and sll she could think about was the day before, and what L kept saying to her.

It was three in the morning, and Haruka and L were the only ones still working. Haruka finally stood up and stretched.
"I'm going to bed," she yawned. "I don't think I can stay awake anymore."
L stood too, and kissed her. "All right. I'll see you in the morning then. You know I love you, right?"
Haruka smiled. "I know. I love you too. You've been telling me all day, I feel special."
He smiled slightly. "I just want to make sure you know."

Thinking back on that, Haruka realized. He knew. He was going to die soon, and he knew it.
In the brief moment that Haruka was frozen, L had hit the ground and Light had grabbed him. Something in Harukla's brain clicked into gear and she lunged for the two on the ground. She pushed Light away without realizing she was doing it and held L in her arms, trying to talk through her tears.
"R-ryuzaki! L! Please don't die, L, please!"
L's gaze slowly shifted to her. Before his eyes closed, he softly breathed "I-i love you..."
As soon as L stopped breathing, Haruka shut down. Her tears stopped, she didn't move, she didn't even look up when Light started screaming that they were all going to die. She almost would have welcomed death. She could hear what was going on around her, but it was far away, like she was hearing it through a filter. At some point, someone -- she thought it might have been Mogi -- helped her into a chair. Someone, maybe Mogi again, she wasn't sure, told her that they had found Watari and he had had a heart attack. She just kind of nodded.
Eventually, everything calmed down a little and Haruka was able to think a little more clearly. She was drinking a cup of coffee, trying not to think about what had happened, when Matsuda came up to her.
"Um, Haruka?'
She looked at him a little blearily. "Yes?"
He held out an envelope. "Ryuzaki gave this to me the other day. He said I should give it to you if something happened to him."
Haruka inhaled involuntarily. "Oh, thank you, Matsuda-kun." She took the envelope with shaking hands and immediately went to her room. When she was on her bed, she took a deep breath and started to read.
Juliet,
Since you're reading this, I assume I'm dead. At least that's the plan, you never know with Matsuda. Please don't be sad. If it's my time, it's my time.
I know that Light Yagami is Kira. I can't prove it but I know it's him. Do not go after him, Juliet. I can not stress that enough. Under no circumstances ar you to try to apprehend Light. He's too dangerous and I don't want you getting hurt, or worse, killed. Let the Japanese police handle it. I want you to go back to England. Go back to Whammy's, and be with your brother. Forget about Kira, forget about Japan, forget about all of it. Look to the future, not the past. And remember that I love you. Goodbye.
Love,
Lawliet
Haruka read the note again, and then once more. "I'm sorry, Lawliet," she whispered out loud. "I can't just give this up. I'm going to bring Kira to justice."

That took a while to type lol. I'm proud of myself that I finally got it up, hope everyone likes it ^^
