I am absolutely late to this thread, but it’s because I’m new. I did not join until recently.
Chivalry is the most romantic thing. But, to be fair, I am such a sappy hopeless romantic. At this point, everything melts my heart. (I least in books and my writing. I know nothing about real-life romance.)
My first thought on when you asked what I appreciate seeing in romance was reading about characters who fall in love with each other by accident, but half of the reason they fall in love is that the other person is already so deeply in love with Jesus. However, looking at a romantic relationship like you have, I love seeing girls (even if they can defend themselves) just feel safe in the presence of their significant other. I like when they can relax, knowing that there is someone who loves them that will protect them from the world. And while not a perfect example, it does point to how the church should feel, safe in the arms of Christ. I think this can also relate to chivalry as well, with the guy performing the traditional role of protector.
Right is right though all condemn, and wrong is wrong though all approve.
