T&B The Beginning’s OP song - Earth Diver by NOVELS
Lyrics

Have we sold our time away?
If so, we don't remember
What was the price to pay?
Eternal life, or maybe the wings of splendor?

Whatever it was, it's too late now
We still have some time left to both act and worry
But above all else, remember the reason why everything must end
The pulse forgotten in a flurry

Nothing is eternal.
We know is all too well
To find means to lose it all.

We fear our words may hurt another
But it's because we've started believing
That our words may save another.

Why do we cry until we're empty inside
Yet no sound comes out?
The gravity of limited time
We know it both throughout

Nothing is eternal
We know is all too well
But maybe there is something
To whom one has found to tell

No flight awaits us, I know it too
But I've been desiring and begging for a moment without end
Ever since I saw the same stars with you

One day our time will stop once more
Never forget it
And hope we'll stay
Side by side forevermore

Nothing is eternal
We know is all too well
But maybe there is something
To whom one has found to tell

No flight awaits us, I know it too
Was it greed that brought us this fleeting life?
So I could see the beginning with you
And one day see the ending through.
