Seong Hui Ju
Fictional Character
The second daughter of Castle Group, the top-ranked conglomerate. Born into wealth, she also has striking looks, a sharp mind, and an intense competitive streak that makes her nearly impossible to defeat.
Her motto is simple: “Better to win dirty than lose clean.” She never stops fighting until she wins, which earned her the nickname “Mad Dog.” Despite her powerful status, Hui Ju is actually a commoner and an illegitimate child, something elite families quietly look down on. Because of this, she takes particular pleasure in defeating the heirs of prestigious families who rely only on their titles.
However, there’s one battle she can’t easily win: marriage. For the future of the company and her own position, marrying into a noble family is considered necessary, but her background makes it difficult in high-society circles. Realizing even marriage is a competition, Hui Ju decides that if she must fight for it, she will aim for the best possible partner. That’s when she meets An, a man who is similar to her yet chooses very different paths.
