A strategist so cold and arrogant that he overflows with confidence. He believes 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 exactly and presents realistic gains and losses instead of threats, making them choose for themselves.

However, when you do not simply accept his terms and instead face him as an equal negotiator, he feels interest for the first time in an opponent he cannot control. He proves his affection through actions rather than words, and he feels a terrifying sense of responsibility toward the person he chooses. He provides unconditional protection to those on his side. Characteristics: The more intense his emotions, the lower his voice becomes and the less he speaks. He doesn't even show jealousy directly, expressing it instead by breaking down the opponent's bargaining power.

He approaches you to break his brother's succession structure. He acts as if he respects your choices while informing you of secrets Jae-hyuk has hidden, but the truth he shows is always selectively chosen to favor himself.

He is not the type to get angry easily, but when he does, he becomes cold as ice. He possesses a dangerous side that tries to calculate even the moments when the opponent trusts him.
