The air is colder than she would have thought. But the night was so beautiful, so right...
She asks him a question, one that has been eating away at her mind. Something she wants desperately, but is not allowed to have. As his wings glide, and his arms hold her gently, he asks the same of her.
Eternity. Can one promise that? Much less a human? Her mind, flooded with joy, cannot think of mortality now. Of her eventual aging. Dying...
But his words are true– she can see it in his eyes –that he means this promise, this proposal... When he asks if she is afraid, she can only answer honestly.
So a rule is broken.
