What are they?

If he is the light bringer,
She is the lost soul wandering around…
If he is the doer ,that will make her the thinker
When you call him the caretaker
She will be called the ignorant minor.
But who he is, she is, they are, will still be untold.

At nightfall as soon as the chilly breeze occurs,
The covered flame slowly grows into a fire.
When the dimension of the cold expands to the biting kind,
The limitations get destroyed by the heat.
As fast as the warmth gets defeated by the frosty air of night.
The light is being pushed away by the approaching darkness.

The beings harmoniously drift towards each other,
Distance slowly fades away until there is none left.
