Ya she has abs, but she also has rock hard bolt-ons. So if you are a natural boob man, then you may not like it.

Also Azzkikr is right, her extras service is not that great and she is money hungry. She is a very logical person and not so naturally feminine charming girl that attracts men, this is why she isn't popular in my opinion. Over the years I've tried to give her more advise on how to attract men but it just goes over her head. Despite her mannerisms, she isn't a fake person, what you see is what you get so I've always just accepted her for the way she is.
