She did it to stop all the noble simps to vote for her and claim they did her a favor (she seems to kinda want the position tho).Dude was reading to much into it, I have a sneaking suspicion that she didn't vote because she didn't want to show favor. She never once said she was interested in the position, if anything I bet she would have voted for him as well.
I mean she could have multiple reasons for going blank, but she doesn't seem that interested in the position to me though. She seemed more interested in fighting our protagonist.She did it to stop all the noble simps to vote for her and claim they did her a favor (she seems to kinda want the position tho).
