Olivia and Alexander found themselves married to each other because of the agreement made by the older generation. However, after meeting each other for the first time, they started to doubt what they know about each other. Olivia, believing that she was married to an illegitimate son of the Maxwell family, holds no expectations of him. Alexander, believing that he had married the debauched eldest daughter of the Shaw family, also holds no expectations of her. With a substitute bride, and a secretive groom, how long will it take them to realise that they didn't marry who they thought they did?
