I saw an image of a knight in full armor saying "Your highness…" to a princess, and her response, "I told you: just call me by my name." And I immediately wanted to read a book with its vibes.
Does not strictly need to be a romance, and in fact something with just under- or overtones might be preferable, since I'm not really a romance reader, but whatever fits the mood works.
Bonus points if the knight is all repressed and stuffy.
