(A/N) Right, so I've never written for 5D's before. Actually, this is the first time I've written for a category that wasn't a book… So I really hope I don't screw anything up!

If any of this is tainted by something from the dubbed version, my apologies. I've only seen episode 59 undubbed because the way I discovered my love for this couple was because I sit and watch the dubbed version with my brother while eating breakfast.

This is the first chapter, and it's mostly just describing Jack and Carly's relationship and it could be considered AU. This story is going to be pretty low on my priority list seeing as I've got other stuff that I should be writing.

Opposites attract. It's basic science, something even young children know. If you place two magnets next to each other, one end positively charged and the other end negatively charged; the two will unite. If the magnets are strong enough, they will never be separated.

Carly was without a doubt positively charged. She wanted the best for everyone, and she had a good heart even if she herself didn't realize it yet. People couldn't usually tell since she hid behind those ridiculous glasses, but Carly always had a twinkle in her eyes.

Jack was indefinitely negatively charged. He used to hurt others, but more than just that, he enjoyed hurting others. He lived for no one but himself. A permanent scowl was always etched on Jack's face.

However, the two together… well that was interesting. They sort of balanced each other out. Carly, who had no cares in the world, suddenly became pensive as she wondered why Jack always had a sour expression on his face. And then there was Jack, who found himself putting someone else first.

That's not to say they lost their personalities, the qualities that made them who they were. Carly was still clumsy and she still got excited over stuff that honestly wasn't that great. She ran all over the place acting like the spazz that she was, but when she saw Jack wasn't having as much fun, she sobered up. And of course, Jack was still pessimistic and Jack was still mean, but not in a spiteful way. He was mean in a "You're so amusing I can't help but tease you" kind of way.

She was crazy about him. Carly never bothered to deny it. She didn't bother trying to conceal the way her heart beat a little faster when she saw him, or that she thought the way he carried himself was ridiculously attractive.

Jack pretended like he didn't care for her as anything more than a friend. He always told himself that she was too happy and carefree to deal with all of his troubles. But really, what he meant by that, was that he knew she was too good for him.

But then, everything changed. You could say that their polarities were reversed. Suddenly, he was the one saving her and she was the one who was determined that she didn't need to be saved. She was a Dark Signer, and he was the one destined to bring her and her kind down.

Her laugh used to be endearingly dorky. Then suddenly, it became full of malice. Jack didn't like to see that, in fact, Jack detested seeing her hurting. But the worst part was that she didn't even know she was suffering.

At least, she didn't realize it until he told her how he really felt about her. When he told her she was the only one he truly loved, he got through to her. He didn't realize it, but Carly had been waiting to hear those words for a long time.

It sucked that once everything was out in the open, Carly had to die. When Jack held her, he couldn't help but acknowledge how unfair the situation was. The only girl he'd ever given his heart to was snatched away from him cruelly.

Jack thought bitterly on her death and their separation. Death was too strong of a barrier to breach. And if one of them had to die, it should have been him, not the innocent girl who was caught in the wrong time at the wrong place.

However, Carly thought otherwise. Jack had to stay alive to save the world; he had to stay alive because he was Jack. If he would have stopped his heart from hardening, he would have realized that Carly would never leave him and that they'd be together someday.

And they would. Someday, the two would be reunited. But this time, they wouldn't be separated because after all, you can't fight science.

(A/N) I'm not sure if I like the way I executed this, it's pretty short =/

If anyone wants to recommend something for the next chapter, feel free to, but if it revolves around a particular episode, you're going to have to tell me the episode so I can YouTube the undubbed version.
