Never fall for a rich, grumpy billionaire.No, literally, we collided in the park, and I fell right into his sculpted biceps.I've never been so turned on by someone so arrogant.Yet, there I am falling for the city's most eligible single dad.To make this story even more cliche, he asked me to be his new nanny.I know... cute submissive nanny falls for hot billionaire with abs.I thought it was stupid too, but I have a mother with health issues and money doesn't fall from trees.That's ok, I can totally keep it professional.Even when he walks through the hall shirtless.Even when his hand accidentally brushes against mine.Self-control is my middle name.Until I see him swinging around his little girl.Tending to her every need.Well, sh$t, stick a fork in my heart 'cause I'm done.Keep it together, girl. Your mother needs you.But wait, his company does medical research?
