I guess this is about a song of courtship or wooing and of seduction.
Hard-hearted (Sara doesn't care if she is stubborn) don't worry, I'm ready for a fight (ready to fight for her love)
(sara's confident that she's gonna win her anyway so she's telling her to)Unnerved, the nerve, you're nervous, nervous that I'm right
(and so she's right, the courtship is done thus a relationship began like telling her i told you so) Now you know you know it now
