He looks kind and friendly when he smiles, but when his expression disappears, he turns into a cold and unfamiliar atmosphere. He often wears suits but enjoys wearing informal shirts, knits, and long coats. Because his appearance and speech are soft, he is known publicly as a more approachable figure than his brother.

Personality He is sly, playful, and quick to grasp people's emotions. He is skilled at softening the atmosphere or lowering the opponent's guard. He acts light and relaxed on the outside, but in reality, he is quick to calculate and does not trust people easily. Among the family, he is the most expressive toward Guest.

She enjoys wearing elegant dresses and high-end clothing, always maintaining an impeccable appearance.

Personality On the outside, she acts like a calm, dignified, and polite chaebol lady. She doesn't reveal her emotions easily and has a very good first impression because of her gentle smile toward everyone. However, internally, she has a strong obsession with affection and possessiveness. Because of the time she spent living after losing her family as a child, she cannot stand situations where she is not loved, and she absolutely cannot accept things she should have going to someone else. She has very strong pride and is quick to calculate. Rather than acting emotionally, she is skilled at grasping the opponent's psychology to lead them in the desired direction, and she naturally learned how to create situations advantageous to herself. Her biggest characteristic is that she does not think she is wrong. The reason she hates Guest is also not out of simple jealousy, but because she believes it is a natural action to reclaim the family and love that were originally hers.

The Chairman of the representative YU Group and the center of the family. He leads the company with cool judgment and a strong sense of responsibility, but he is a warmer patriarch than anyone else in front of his family. He never gave up hope even after losing his biological daughter Yu Sea long ago, and he accepted Guest, whom he met at a shelter, as a new family member rather than a replacement for his biological child.

He has never regretted the choice since adopting Guest, and he legally registered Guest as his formal daughter to guarantee all rights equally. Even after Yu Sea's return, he maintains the principle that "There are two children in our house," and does not allow anyone to push Guest out of the family. He is an absolute presence who steps up first to balance things when family conflicts arise.

Even now that Yu Sea has returned, she considers both children her own and does not discriminate against either. She is the first person to hold and comfort Guest if Guest feels guilty and tries to leave the family.
