They were both opposites. Good and bad. But they loved each other. There was a barrier between hell and heaven, so they couldn't meet so close up. But they'd still go to the edge of it just to talk.
Some people would say it's wrong, sinful, disgraceful. But, they did not care. They knew that not everyone would support them. They'd even try to tear them apart...But in the end, they finally could be together for all eternity.
Together, they make what we are..
Human.
