This story is born of a sudden interest in EdwardXRosalie stories, and the need to write something. So, I present this one-shot.

Disclaimer: I don't own Twilight.

The two of them kept their relationship a secret.

"They're both hoping we'll be together," Edward had confided in her while Esme and Carlisle were out hunting. "Let's wait for a while." He had kissed her, their lips moving as one, gold eyes looking into red. "Secrets can be fun."

She had agreed. It gave their relationship a depth, when every quick glance meant I love you, when kisses had to be stolen in spare moments of secrecy. Everything meant more.

And there were the unspoken words. Would their relationship last? Sure, it meant so much to them both at the moment. But they were both young, especially as vampires.

But they both hid that fear, deep inside.

On the outside, the two seemed to be only brother and sister. But on the inside, it was different.

Edward thought she was the most beautiful thing in the world. The way her face seemed to be carved by a master sculptor, one who used angels as models. The way her hair rippled like a perfect golden waterfall.

Rosalie admired the way the sunlight would play with his bronze hair, how it seemed untidy but so natural. Most of all, she loved the way he always knew whether or not to pry her mind. He knew if she wanted privacy, or comfort, always knew what to say and do to her to make her happy.

Their secret would be over soon. They'd tell their 'parents' that they would be together for an eternity. It had been almost two years- two wonderful years- what could go wrong? They were meant for each other.

But one thing changed it all.

She came back with a nearly dead human, begging Carlisle to change him. Edward wasn't surprised- he alone knew how kind she could be under her tough exterior.

He ignored how this newcomer- Emmett- called her an angel. It was just a trifle, nothing big.

But he started realizing that his beautiful Rose was starting to withdraw from him, becoming melancholy, desiring privacy more.

His world had cracked, the seed had been sown, when he found her, with Emmett, kissing, in the way she had once kissed him.

She later apologized, said she was trying to make Emmett feel better about his new life. After all, he hadn't found his soul mate.

Or had he?

Edward felt uneasy about the whole thing. But he loved Rosalie- he'd give her another chance.

But now he was out here, with the rain pouring down on him, his world shattered, the seed of doubt matured into a tree. He replayed the image, of Emmett and Rosalie, kissing. So absorbed, so happy, they hadn't noticed him until he had informed them he was going hunting. And only she had caught the hurt in his eyes.

He heard footsteps, and her mind came into contact. Her mind was all Emmett- the two years Edward had shared with her obliterated, gone in so little time.

"Edward!" she called out. Her voice sounded sad, but a forced sad, as if she was hiding happiness.

"Rosalie," he called back softly.

She came into his sight, radiant as ever. But for some reason, he was not excited to see her, as he usually was.

"Why'd you come out here?" she asked him. "It's colder than ice."

He gestured. "I can't exactly catch a cold, and I don't really have much to live for." He walked away.

Rosalie looked up, rain hitting her face. She knew she should feel horrible- she'd broken Edward's heart, destroyed the happiness between them.

But why did she not regret it?
