For me? I like to have a range of different relationships (and kinks of course) to explore with my Steele.
Azra feels like a cuddly relationship that can build a bit here and there, even if it hasn't yet. It always irks me with alot of crew members that you sort of get whacked in the face with most relationships being locked at 'early dating' or 'friend you have sex with' which gets a egregious when you have bred like ten children with some of them (not counting multi-births, in which case let me grab a calculator).
Azra on the other hand seems like she has potential to have a more mature and sweet angle with Steele, which would add some nice diversity to the game. Granted, diversity is always my big ask since I like having as wide a net as possible for things to do in the game. Although I also want a dreadnought warship to smite Steele's cousin with, so taking my preferences into account is dubious
I also wish she had something for double penning her, but I sort of want that out of everyone
