Cormac is used to doing everything in his power to achieve what he wants. Use or be used is his motto, and he is NEVER used. When he is required to present a wife and prove he is a family man, the bachelor simple blackmails his secretary in to following his plans.
Lizzie may be under duress in playing Cormac's wife. Finding out that he is using her feelings against her to win a contract is more than she can bear. Hoping that love can conquer all is a very unlikely senario.
A very touching, sweet story.
