translation question for western readers

would it put you off if a story keep it honorific from it's original language. idk why translator keep taking them off and replacing it with just a name... it loses parts of the tone and character for most characters.

and similarly, would it put you off that couples would use honorific for siblings for their s/o? that's the only reason why I think some of these translator take the honorific off tbh. like hyung and oppa is originally for family members. but you can also use this for ppl outside of your family. this is not a weird concept but I've seen certain people take the "family" part too seriously and can't seem to wrap their head around that concept.
like you can't ship character who call each other's "brothers" even tho they're in no way related to each other. example of this is a zenless ship, Billy (a robot) x Lighter (human), who met at an underground fighting ring. they're not related, so not incest, and they don't grow up together, ruling out pseudoincest.
