As the title says, they must be 25 or older(main characters)r and in a relationship from the start of the book with no fake out breakup or anything, just a normal relationship alongside the plot, so no romance books .For the genre, i feel i already asked too much as is so as to not wall myself off too much i will leave off the genre, i don't mind most genres but prefer something grounded and outside of the usual fantasy and sci-fi.
