Face of a Fighter Lyrics

These lines in my face caused from worry
Grow deeper as you walk out of sight
Mine is the face of a fighter
But my heart has just lost the fight
Round one you told me you loved me
And I felt my heart falling there and then
The last round you walked tall and left me
And I guess my heart's losing again
Mine is the face of a fighter
I fought for your love with all my might
Mine is the face of fighter
But my heart has just lost the fight
Yes mine is the face of a fighter
I fought for your love with all my might
Mine is the face of fighter
But my heart has just lost the fight
