Why not just say it's not Miss Heroina's doing, and say something along the lines of "seeing that I'm protecting my fiance, the one whom I have committed for now (and forever), wouldn't that make me a good man who honors his commitments (and will not be yield by her)?" Or "seeing that I'm bringing justice to what's wrong, wouldn't that make me more likable as a man and royalty who wouldn't stand for violence?" Girls like a devoted man to his promises right?
