SOLVED. Boss and assistant romance. [s]

[Shelia]

All i remember is a girl works for a temp agency, they called to have her be a assistant for a billionaire boss because his regular assistant whose name is judy or ruby (I'm leaning more towards Rudy but now sure) has some family emergency. I remember one part about the button on her blouse pops off and she is under the desk looking for it when he comes out of his office. She tries to hold a notepad in front of her to hide the missing button. He eventually tells her the "Judy" has a sewing kit in the desk drawer. Sorry that is all i remember i hope it helps.
