Wow thats harsh... Annie is just materalistic, I dont think that you can call that an attitude. It's not like she hurts others on her own behalf (except maybe for stealing a bit of Mielles cosmetics). She does help Aria set up people and plays her role as an arrogant maid well but no one can say that these people don't deserve what's coming for them.
Also Bourbon has a crush on Aria in the beginning but he truly starts to like Annie later on. And Annie works hard for him to like her and she doesn't do so just because he is a noble.
I think that if someone works hard on their own knowledge, appearance and manners to be acknowledged by the person they like, than we should show them more love..
I like Annie who is ambitious and works hard to lead a better life more than Jessie, who is always timid and tries to refuse all the good things she gets, be it meteralistics or love.
It's okay I understand you.. I like her ambitious personality.. she dream too improve her living conditions.. to me Annie is important to Aria because she's the one doing all dirty work for Aria because Jessie isn't good at doing it.. tbh Annie is a typical character that you usually see in many royalty/noble stories the type that is ambitious and tad bit greedy but the good quality about Annie is she has a good judgement she knows that if she keeps following Aria things would turn out good for her and Annie know her limit and not to go overboard or else Aria wouldn't hesitate to eliminate her.. plus even if Aria did help her with the Duke it's Annie cheerful personality that also caught his attention..
iM SORRY I WAS LOWKEY SHIPPING ARIA N THE BOURBON GUY
