I'm indeed a sucker for enemies-to-lovers (it's my favorite sub-genre of smut to request from Chastity's Nook!). There are whole folk tales of Zullie's adventures with Alva before she confessed her love for him - a great deal of the time she would use cunning to defeat local adversaries when Alva could not succeed with his philosophies. She's known for slaying a dragon with nothing but poison knives!
