Sayu sat back enjoying the peace. Matsuda was at work and it was her day off, so she was enjoying the most of it, using her time to relax. She heard the door shut and got up to see her fiancée –Matsuda Touta – standing in the doorway. She walked over and wrapped her arms around his neck, kissing his cheek, but she immediately let go when she saw the pain and horror in his eyes.

"Matsuda, what's wrong?" She asked anxiously. He was never gloomy and she hated seeing him like this. "Baby, what is it?

He sighed shakily and slumped against the wall, his head in his hands. "I-I'm a killer!" He whimpered, and she stroked his arm and he leant into her side. "I killed Kira!"

"That's a good thing, isn't it?" She asked. Kira was a serial killer who had murdered criminals in the form of – in most cases – heart attacks, with the help of a book called the 'death note'.

He shook his head. "It means I'm no better than him, he killed criminals, making him a criminal himself and if I killed him then..." He trailed off into silence and she shook her head angrily.

"No Matsuda! You did what was right, if you hadn't killed him, he would have went on to kill thousands more! Surly one death is worth saving more, especially when it's someone like Kira's life..."

"No Sayu! Kira wasn't all bad... I mean he was-" He stopped and looked at her with pleading eyes. She could tell there was something there that he didn't want to tell her, but she wanted to know; she hated secrets.

"… He was what?" She urged him, trying to get him to tell her.

"Kira was... your brother, Light Yagami. Light was also my friend."

She stopped. Someone like Light could never be a heartless killer. Could he? Light had been the most caring brother and was such a kind, hard working pupil... 'I guess anyone could turn evil.' She thought, and tears rolled down her cheeks. "So those rumours about Kira killing Light were..." She swallowed. Even if he'd been evil, she couldn't help loving her brother.

"I'm so sorry Sayu. I love you, please forgive me I-" Matsuda begged and she took his hands in hers.

"It's ok. It's your job right? He's a criminal and if you hadn't... Killed him; he would have killed you." Although she said it, part of her was still upset with Matsuda because, as hard as she tried not to, she still missed her brother and no matter how much she loved her fiancée, he had killed Light; but it was for what was right so she couldn't stay mad for long. The thought of loosing Matsuda was much more terrifying. "I love you." She whispered, just loud enough for him to hear. He looked up at her from where he was slumped on the floor.

"Promise me you won't leave me." He pleaded and she bent down to sit on his lap. "Not for this. I regret it Sayu, anything that causes you pain. I'm sor-" She pressed her lips to his, shutting him up and showing him how much he was forgiven. He'd done it to save his and Sayu's father's life.

'If Light had been willing to kill our own dad... he was better off dead.' That's what she kept telling herself anyway. Her mind kept drifting away, remembering times when light was her best friend as well as her brother. He helped her with homework and they had watched television together, curled up on the couch. She remembered when they were both young, he used to put up with her wanting to play with dolls with him, and as these memories flowed through her mind, tears filled her eyes and she felt Matsuda's warm hands caress her face.

"Sayu… I'm sorry…" He apologized, but she pulled him into a hug. She knew he was hurting too.

"Don't apologize… You did what was right… You couldn't have let the fact you knew him interfere with your task anyway. He was a criminal." The tears kept flowing and she buried her head into his neck so she had his scent around her. A horrible thought suddenly occurred to her, and she shivered.

"Are you okay…?" He asked, feeling her tense up.

"Yes… I just thought about the fact he killed so many… Even people he knew and had once loved. S-So what if it had been you…?" The thought of her lover dying was too much for her and she broke down into tears. He stroked her hair, trying to comfort her, so glad that she wasn't angry at him.

"I'm here…" He reassured her. "With you. And I always will be…"

She smiled up at him, tears still trailing down her cheek. "Thank you…" She whispered. Sayu knew this would take a long time for her to get over, but she also knew that thanks to Matsuda, she could get through this.
