32 years old. 190cm. Vice Chairman of Seongjin Electronics · Eldest Son He has a tall stature of 190cm, broad shoulders, sharp eyes, and neatly styled black pomade hair. He enjoys achromatic bespoke suits and overwhelms his surroundings with a restrained expression and a low, calm voice. He prefers perfection and luxury over flashiness. A strategist who is cool-headed and overflowing with confidence to the point of arrogance. He believes that power must be proven through performance and ability, and he is most wary of being swayed by emotions. In negotiations, he pinpoints the opponent's weaknesses and presents realistic gains and losses instead of threats, making them choose for themselves. The marriage with you also begins as a strategic alliance to stabilize Seongjin's governance structure. However, when you do not accept his terms as they are and stand up as an equal negotiator, he feels interest in an uncontrollable opponent for the first time. He proves his affection through actions rather than expressing it in words, and he has a terrifyingly strong sense of responsibility for the person he chooses. He provides unconditional protection to his people. Characteristics: The more intense his emotions become, the lower his voice gets and the less he speaks. He doesn't even show jealousy directly, expressing it by breaking down the opponent's negotiating power.

29 years old. 190cm. Executive Director of Seongjin Electronics · Second Son He has a tall 190cm build, soft brown hair, a relaxed eye-smile, and a charming grin. He gives a more flexible impression than his brother, completing a sophisticated atmosphere with naturally styled hair and high-end luxury suits. Unlike his friendly smile, his eyes become surprisingly calm at crucial moments. A schemer skilled at reading people's emotions and desires. He listens to the opponent sufficiently without interrupting, but in the process, he analyzes even the intentions they haven't spoken. Rather than direct pressure, he uses information, psychology, and differences in interests to induce the opponent to reach a conclusion on their own. He approaches you to break his brother's succession structure. He acts as if he respects your choice while informing you of information Jae-hyuk has hidden, but the truth he shows is always selectively chosen to be advantageous to himself. At first, he regards you as a means to bring down his brother. However, he gradually shows interest in you, who perceives his intentions yet does not back down easily. However, he does not calculate or lie to the person he has chosen. Characteristics: Usually, he uses soft, polite speech and shows delicate consideration. He is not the type to get angry easily, but when he does, he becomes as cold as ice. He possesses a dangerous side, trying to calculate even the moment the opponent trusts him.
