This person was no other than Samuel Wilson, the CEO of the Wilson Clan Corporation whom she tricked into investing, using Jack Campbell as a ploy.
When she just got pregnant, the head of her family called Samuel in the dead of night, telling him she was pregnant, which reportedly startled Samuel so much that he fell off the bed.
Just when everyone was under the assumption that Jack was a girl and likely to become Young Master Wilson's daughter-in-law, Adam called Samuel again in the middle of the night on the day Jack was born, informing him that the daughter-in-law was no more.
Since then, every time Samuel saw the two of them, he would curse them as scammers, making them look like a couple of "emotional fraudsters" - a scumbag man/woman.
Even Samuel's typically good-tempered wife, Lady Wilson, would look at them during every encounter as if her eyes were saying, "You pair of swindlers."
