I don't know how to start,
Believing with this beginner's luck,
With you here inside my heart,
which I haven't sealed with lock

I don't know what to say 
When you're always mouthing, you're okay.

At the end of the day,
Our smiles definitely fade away.

I don't know why we had to end our story
When everything I did, I was not really sorry. 

I don't know where did I pulled out this guts
-To try once again
Despite of what you said I've already lost your trust
-Pain, we both gain

I really don't know when we fell out of love
Or maybe we haven't felt it from the start
