How does the author announce to the audience the theme of love

Le Bret calls the men “duel-mad” (39) and says Cyrano should not be like them. He has too many enemies, Le Bret says, and asks what his aim is. Cyrano replies he wants to be admired. He admits he hates Montfleury because he thinks he is God’s gift to women, and that he himself is in love.
