I just love love the idea of r/s being exceptions to each other. passive, conflict avoidant remus demanding that sirius listen to him when they fight and impulsive, confronting sirius calming down and taking the heat coming from remus cause "woah he'd never ever lose control for nothing!" but also, sirius, the infallible, being vulnerable with remus and admitting to being lost here and there!
i hope it's okay to preserve your tags here because you've articulated this specific, vital aspect of their dynamic so well. that their relationship is as noteworthy, romantic, and meaningful as it is in the text because it shows how far they're willing to compromise for each other, in a way that is endlessly forgiving of not only the other person but also of themselves! they are each other's redemption! tangentially, this is also why i find it hard to believe that either of them would hold a grudge (post-poa especially) or manufacture drama in a 1:1 comparison to ron/hermione or whatever is the most recent fanon template for romance that fans will happily apply to r/s and pretend is canon-compliant. in fact, their biggest source of drama literally stems from how unconditionally compromised they are for each other, where protecting each other despite suspecting the other had thrown in with voldemort and was willing to (successfully) murder their closest friend and his family is actually a hugely valid source of guilt. to the point where it kind of doesn't even matter that both were innocent, like just look what they are willing to let each other get away with (this is specifically in keeping with the implication that sirius didn't tell anyone that he suspected remus in the first war and that he didn't confront remus personally either, despite sirius's double standard for peter and his tendency towards proactive justice, especially when his family is in danger).
when i first got into r/s, i was briefly convinced that there were so many odds stacked against their relationship, so many reasons to give up on each other, that it didn't make sense in a canon-compliant reading. but the truth is that this is actually the point, the most compelling aspect of their ship. they hold onto each other so tightly in spite of everything, even when it hurts, even when it doesn't make sense, for the simple fact that they simply love each other...like, they just do. they choose to balance each other on purpose. they grow as people and step out of their comfort zones for each other. they are the definition of "i love you on purpose."
