If only I had known
               You will do me such wrong.
If only I had known
              The damage would be so strong.

If only I had know
              You had a heart of stone.
If only I had known
              I would be stranded all alone.

If only I had known
              You were not mine to keep.
If only I had known
              The scar would be so deep.

If I had known it all,
              Before I gave you my heart.

Would things have been different?...
