He is trying to remember this is a fake engagement...
Natalie Shaw has been healing from a difficult marriage while living with her sister, Dr. Rayne Sterling, and her husband, Lord Edwin Sterling.
Lord Alex St. John has spent his adult life being pushed by his mother find a wife. He had been betrothed and due to actions on the young lady's part, he broke off the engagement. Now he must attend his cousin's five day wedding celebration and expects to be harassed by all his female family members, with numerous women dragged before him for consideration.
Over drinks at their club, Lord Sterling suggests to Alex that he take Natalie as a 'pretend' fiancée to ward off all the trouble he is about to face. Natalie reluctantly agrees.
Their plan appears to be working until Alex's former fiancée arrives for the wedding, determined to win Alex back. Not only does he have no intention of doing so, he's beginning to believe his 'fake' fiancée might be his perfect 'real' fiancée. However, there is desperate maneuvering on his ex-fiancée's part, because not winning Alex back is not an option.
