YoOO I like this-- the answer is, of course! Raven and Rose are humans, they have their good and bad traits, and they won't agree on everything all the time. I won't elaborate on Rose because Rosefinch is @synclonization's OC, but I can speak for Raven.

Overall, they are quite like-minded, you would normally not find a lot of clash in their day to day lives as they're both indoor persons. That being said, Rose is a very morally grey person, and this is from the start their biggest source of conflict, as Raven has a certain set of morals she won't change, and is present even in her work as an assassin.

They eventually get around this and get to know each other and actively try to understand the other, even when they still wont always agree in certain aspects. Outside of this, Raven does dislike her lover's workaholic side, but it comes more from wanting Rose to enjoy her free time a bit more or give herself something else to focus on rather than see it as boring, which isn't the case since she likes listening to whatever rambling her girlfriend will make.

That's the two biggest out of my mind, anything else would be too small or related to their complementing personalities, which goes into the same sack of 'they eventually get to understand each other'.
