I belong to Mr. Whitlock?

It was just another day at work for Mandy, till she pumps into a handsome guy whom she never seen before but besides his looks she was completely driven away by his "rudeness"
Later on she finds out he's Seth Whitlock the Son of the companies owner also he happens to be the president of Whitlock's tower where she works at. She's completely mesmerized by his handsome features.... To be exact it's his nonchalant and obnoxious attitude that truly annoys her which she wishes to have nothing to do with him. But when Seth presents her an offer she cannot refuse... She is forced to think again, all she has to do is pretend she's Mr. Whitlock girlfriend for an entire week while they visit his rich and high standard family. Will she stay long enough to see the end of her deal or will she walk out on her handsome Mr. Whitlock? How bad can it be?
