Not exactly, if the Kari is whore flag becomes true she does whore herself, only thing you can choose whether or not see it. Making flag true is also too easy, just not be on her path.
Yeah the excuse of every whore, ain't it? Life is a bitch for everyone, she is not in immediate danger about the money. Also MC is willing to help, accepting help from a friend should not be as degrading as becoming a whore. Almost all of the interns, which is huge part of ASI, lives on the same rates plus rent for them. Also MC promised to increase living standards of the interns and making efforts towards it, it's only matter of time. He even suggested a plan to ease ASI girls into life. Giving some rent benefits, helping them until they reach 21 instead of 18 etc. She also works as a waitress in that same bar, so she is earning more than $1000. All in all, this is food for me is weak ass excuse. She could have said, fuck off you have no authority on me and I'd do whatever I want to MC and would be better than what we had.
In anyway, Kari being whore is not the problem itself, my concern about it is how she become one. If Kiki starts to whore herself, I'd probably say figures, but not with Kari. Same goes for Cassie and a few other LIs too, there is no background.
