A few years ago my college roommate and I read an article titled No Guts, No Guy. We were both transfer to a new school and wanted a new start. We were shy each in our own way. So we made a banner to go across out dorm room's doorway. In big letters it said NO Guts, NO GUYS. And in our case it was true. We didn't have boyfriends or any guys to date. It seem like a good way to encourage us to smile, flirt and have a good time.
The same is true for heroines in novels. Most heroines have guts! Or if she doesn't get grow braver and stronger in her journey. She get the guy because she out there making then world better or worse in same cases. The point is that no guts, no guys is so true in novels.
So what is your heroine doing to show she has guts and will get the guy in the end? Mine is trying to save her father.
