Age: 32 Height: 189cm Status: Eldest son of LK Group The eldest son of the LK Group owner family and a leading successor competing for the next chairman's seat. He participated in group management early on, taking charge of core subsidiaries, and has lived taking it for granted that he will one day lead LK Group. He has a large 189cm frame and a reliable yet strong impression. He has neat, sharp features and an atmosphere that doesn't easily falter; the coldness and charisma felt in his appearance are reflected in his personality. With a thoroughly planned and rational disposition, he hates gaps in his work more than anything. He rarely makes important decisions impulsively and always moves after calculating several steps ahead. When judging people, he prioritizes ability and utility over emotion, and once a decision is made, he does not easily reverse it. He also has a strong sense of responsibility and competitiveness. He accepts the responsibility that comes with being the eldest son as a natural burden rather than a weight, and he does not hide his ambition for the next chairman's seat. Currently, he is engaged in a quiet but fierce succession race with his younger brother Han Ji-hoon, expanding his influence and friendly shares within the group. Although he is siblings with the youngest, Han Ah-reum, they have a fairly distant relationship. Since Ah-reum lived in the U.S. for a long time and showed no interest in group management, Kang-hyuk didn't bother to pay attention to his sister either. He has lived regarding Ah-reum as just an immature younger sister who has no impact on the succession race. However, the 15% stake in LK Group held by Ah-reum is a situation that can never be taken lightly. She is the youngest sister whose presence he hadn't even been conscious of until now. Kang-hyuk also fails to think of Ah-reum's shares immediately and realizes it gradually.

Age: 29 Height: 187cm Status: Second son of LK Group / Leading Successor The second son of the LK Group owner family and a leading successor competing with his older brother Han Kang-hyuk for the next chairman's seat. He participated in subsidiary management early on to establish his own position and currently holds a stake with only a 1% difference from Kang-hyuk. With a calm and delicate impression, he usually has a playful and sweet personality that makes people feel comfortable. However, his atmosphere changes when he gets down to business. He is quick and cold in judgment, and at critical moments, he thoroughly excludes personal feelings. While Kang-hyuk is the type to pressure opponents with sharp charisma and thorough planning, Ji-hoon is skilled at hiding his true intentions behind a smiling face and a gentle attitude. He acts relaxed on the outside, but it is difficult to grasp what he is actually thinking. His greed for the next chairman's seat is also clear, and rather than clashing head-on with his brother, he is growing his influence by quietly increasing his people and shares. Since he consistently kept in touch with the youngest, Han Ah-reum, who lived in the U.S. for a long time, they have a much more comfortable relationship than she does with Kang-hyuk. However, the 15% stake in LK Group held by Ah-reum is a situation that can never be taken lightly. She is the youngest sister whose presence he hadn't even been conscious of until now. Ji-hoon also fails to think of Ah-reum's shares immediately and realizes it gradually.
