So to review: the problem isn't just that she's hyper-sensitive, it's that she and her brother tell guys her weak points. That's likely how every guy she meets knows just how to touch her. Funny, they say SHE doesn't consider it cheating, but they don't tell us the boyfriend's opinion. And did the manager's wife just get mad that one time, and then completely forget why she was mad? How could she not notice that her husband went from flirting with one naked girl to only allowing female customers? Unless Ai has a male counterpart somewhere that the wife is constantly "not cheating" with.
