If you do the quest for her husband to be she will be kinder to you.
I did the quest and he's nicer, but she isn't. Constantly telling me to get out if I don't have money.
she's just sort of a prickly sort of gal. Even her hubby-to-be gives some illusion to this when he talks to you about her and the ring. she's never gonna be a teddy bear and sweeties kinda gal. He likes her that way. I kinda like her that way, too.
Yeah, they are sort of opposites of one another. It's just that I managed to befriend the other rude shopkeeper in Solitude and now she's nice to me, but I did that by investing in her store - which automatically makes the shopkeeper your friend. You can't invest in Keerava's store, because it's just a pub.
I'll just keep dropping different items for a little bit. Although I have to reload every other time because a fight keeps breaking out. Mjoll has murdered several people trying to get fine clothes and jeweled necklaces. So much for honor.
