50 Shades of Grey

Mr "Rich Guy Grey" falls in love with Anastasia Simple Lady

He falls in love with the modest, plain dressed woman/young lady.

"Lady" is emphasized.

He is surrounded by women employees/co-workers in his office
who try to be sexy with their dress/attire, wear lots of makeup,
have made obvious trips to the beauty salon to "make themselves
beautiful and attractive" and 
who act / pretend to be sophisticated. 

He is not interested in any of these women.

She is a romantic English lit major who loves books.
She is "boring", doesn't do much, isn't in to anything fancy or expensive.

She is a little shy. She is sweet, simple, pure, clean, innocent, unassuming, demure,
naturally beautiful and polished. His mother is impressed with her. She approves.
Mother hasn't met any of the other women before her.

She wears little to no makeup or jewelry. Her hair is natural and long.
She has no tattoos. Nothing flashy on her body or in her
surroundings at her apartment.

She speaks slowly and clearly, without foul language. She is a lady.

She shows him she doesn't need his money.

She works at a hardware store, then for a book publisher.
She can take care of herself. She doesn't have to have him.
She does not chase him. 

She is not impressed by his bank account,
his "intelligence", who he knows or
what he (thinks) he knows or his financial genius.

She is not impressed by his things, his enormous house,
his cars, helicopter or any business he owns.

She promptly leaves him when he is mean, cruel and unethical.
He stalks/finds her, chases and hunts her down then
surprises her by showing up in her apartment after
she told him, "It was nice knowing you".

She tries to understand his pain. He doesn't want to talk about it.
He says his mother was a drug addict as if "need I say more"
explains it all.
