Forgotten plotlines

I really like this manhwa but I feel like there r so many plot lines of the week that just get forgotten? Like, we never see the ML's little brother after the first couple chapters even though, she's supposed to be using holy magic on him all the time. Im disappointed we dont even get to see him interacting with his brother ever even though that was such a big thing early on, now its like he doesnt exist. And then did the alcoholic slaves ever get resolved??? Maybe I skimmed past it but I never saw them actually kick out the ppl who were making it hell for others.
