Footsteps.

I was following the footsteps
Every each of his footstep I saw
Without once realizing that
I've gone a way too far
Too far that even his very first footsteps had gone
And I had no way to go back again

All I could do at that moment was only following
It was a long journey with hard work 
That was worth fighting for
But what if this journey has no end?
How far should I continue to go on?
What if I stop and go my way?

Even if I continue walking behind your back
Have you ever noticed that?
You kept walking
Without once turning back
Without once seeing me
Who stepped on your footsteps diligently
