Maius Intra Qua Extra

Good luck! And, hey, you can subvert tropes all you like - maybe even the romance novel square is possible with the Unconventional Courtship Generator! (I'd never write a romance novel myself, but I've subverted the summaries and played with the generator a lot since Unconventional Courtship started up as a fest and, frankly, it's the only thing most of those summaries deserve!!)

But, yeah, you only need one row, and there are lots of ways to go about it. Have fun!
