Moira was the Cooper family's eldest daughter and the most beloved child in the family from an early age.
Like the Donnie family, the Cooper family was a wealthy and influential family in the world. Still, very few people knew about the Cooper family, not even the Donnie family.
When Moira visited the Donnie family, she fell in love with Greg at first sight.
Then, Barlow suggested that Greg and Moira should get engaged.
However, Greg had no feelings for Moira whatsoever. They had barely met since childhood, and Greg was unaware that Barlow had arranged their engagement.
Later, when Barlow revealed this fact to Greg, he was shocked and made it clear that he refused to go through with the marriage. But Barlow insisted that he marry Moira, which led to a heated argument between Greg and Barlow, and ultimately caused Greg to leave the family in anger.
Eight years had passed since Greg's departure.
