What is it?

I can see something in your eyes
When you gaze me
I can feel something in your heart
When you smile to me
But you never tell me
What it is

Now you gone
Before tell me
What it is
In my aloneness
I sing your memory song
But it can’t tell me
What it is

I know you will back
I’m here waiting for you
Waiting you to tell me
What it is
