Myunghan Yoo

Myunghan Yoo is the chairman of Yoojin Construction and Jinho Yoo’s father. His severe manner conceals a protective parent and a patient judge of character whose relationship with Jinwoo develops from investigation, through rejected negotiation, to profound trust.

Biography

Chairman of the Yoo family

Myunghan is the eldest son of Yoojin’s founder, Byungchul Yoo, and one of Korea’s wealthiest businessmen. Despite an unforgiving schedule, he personally conducts his father’s annual memorial ceremony. The ritual reflects his respect for family obligation and helps explain why his children experience him as both provider and unyielding authority. His broad, stern face and controlled speech make even private conversations feel like corporate negotiations. (Chapter 14)

Jinho, the youngest son, appears ill-suited to this environment. Myunghan does not display encouragement openly, but watches him more closely than Jinho realizes. When Jinho presents the guild-master license earned through nineteen raids, Myunghan has already investigated Jinwoo Sung, including testimony connected to the Red Gate. Rather than dismissing his son, he sets a test: recruit the extraordinary hunter and prove that the proposed Yoojin Guild can be built around trust. After Jinho leaves, Myunghan permits himself a private smile at the “tiger cub” beginning to show independence. (Chapter 19)

A guild for family security

Myunghan explains that Yoojin Guild is not principally a profit project. Awakened hunters are becoming military powers beyond conventional wealth and law, and he wants dependable strength close to the family. This makes Jinwoo valuable not only because he is powerful, but because Jinho trusts him and the evidence suggests that trust is deserved. (Chapter 27)

Jinho nevertheless chooses to help Jinwoo establish an independent guild. Myunghan freezes his accounts and expels him from the family home, insisting that an adult choice must carry adult consequences. The punishment appears cold, but privately he is proud: for the first time, Jinho has selected a path rather than accepting whatever comfort his father arranged. Myunghan’s parenting repeatedly takes this form—testing independence without voicing the affection motivating the test. (Chapters 27–28)

Eternal Sleep Disease

At the same time, Myunghan begins falling asleep uncontrollably. One episode lasts for roughly two days, and medical examination confirms Eternal Sleep Disease. He keeps the diagnosis from his family and most of the company; only his wife, doctor, and secretary know. His secrecy is partly pride, but also corporate risk management: thousands of employees and investors depend on confidence in his continued leadership. (Chapter 28)

When he learns that Jinwoo’s mother recovered from the same supposedly incurable disease, Myunghan orders a discreet investigation. He later meets Jinwoo alone, reveals the diagnosis, and offers a blank check plus an enduring personal debt for the cure. The approach is bold but unusually vulnerable for him. Jinwoo refuses because the Holy Water of Life is limited and he does not yet know whether Myunghan is a man worth saving. (Chapters 49–50)

Myunghan accepts the refusal without threatening him, exposing the secret, or using Jinho as leverage. He understands that coercing his son’s closest friend would prove Jinwoo’s mistrust correct. This restraint becomes the evidence that eventually changes Jinwoo’s judgment. (Chapter 50)

Secret cure and repayment

The disease advances until Myunghan enters its terminal sleep in hospital. Jinwoo uses a shadow previously hidden in Jinho to reach the room and administer the cure without public notice. Myunghan wakes in a case doctors cannot explain, preserving both his life and the secrecy surrounding Jinwoo’s magical resource. (Chapters 52, 55)

Before the Monarch war, Myunghan arranges another private meeting. He learns that Jinwoo changed his mind because the chairman never exploited Jinho to force a cure. The answer breaks through decades of emotional restraint, and Myunghan cries. He offers anything within his power as repayment. When Jinwoo asks for protection rather than money, Myunghan promises to care for Kyunghye and Jinah if Jinwoo does not return. He also asks whether Jinwoo is seeing anyone, transparently considering a way to welcome the man he trusts into the family. (Chapter 68)

Father and chairman in the rewritten world

In the rewritten world, Myunghan remains chairman while Jinho creates Ahjin Software instead of joining Yoojin Construction. He outwardly complains about his son’s independent career, preserving the same formidable persona. In private, however, he clips every article about Jinho and keeps multiple hidden scrapbooks. The erased timeline’s unspoken pride thus survives as a defining part of his character even without hunters or the guild dispute. (Chapter 77)

Appearance and personality

Myunghan is a dignified older man with a broad, severe “tiger” face and an almost unreadable expression. His still posture, formal speech, and disciplined eye contact create the famous poker face that subordinates and family find intimidating. Eternal Sleep Disease adds involuntary exhaustion to a man otherwise defined by control. (Chapters 14, 19, 28)

He is analytical, proud, reserved, and intensely responsible. Myunghan investigates before deciding, remembers faces, and frames family safety in the same long-range terms as corporate survival. He can impose harsh consequences, but does not confuse authority with entitlement: after Jinwoo refuses him, he honors the decision and refuses to weaponize Jinho. (Chapters 19, 27–28, 49–50)

His affection is genuine but poorly expressed. Smiles occur in private, praise becomes a test, and pride becomes a secret scrapbook. The emotional release after his cure shows that the restraint is habit rather than absence of feeling. (Chapters 19, 28, 68, 77)

Abilities, skills, and rank

Myunghan is an unawakened civilian with no hunter rank or combat power. The Holy Water of Life cures him, but grants no supernatural ability. (Chapters 49–55)

Corporate leadership

As chairman of Yoojin Construction, he manages a major conglomerate, commands substantial financial resources, and understands how leadership succession, public confidence, and employee welfare interact. His decision to hide his diagnosis is ethically complicated, but demonstrates awareness that his health can affect thousands of lives and the company’s stability. (Chapters 14, 28)

Investigation and memory

Myunghan collects reliable information before approaching Jinwoo. He connects accounts from the Red Gate, identifies the unknown hunter supporting Jinho, investigates Kyunghye’s recovery, and remembers people well enough to recognize important connections later. His research is discreet and goal-directed rather than gossip. (Chapters 19, 49–50)

Negotiation and judgment

He designs tests that reveal motive, offers terms proportional to what he asks, and accepts a refusal without destroying the possibility of future trust. His greatest success comes not from the blank check but from restraint: by declining to use Jinho as leverage, he demonstrates the character Jinwoo needed to see. (Chapters 19, 27, 49–50, 68)

Limits

Myunghan’s reserve makes him difficult for his children to understand. His punishments can appear indistinguishable from rejection, and his pride encourages dangerous secrecy about his illness. Wealth also proves powerless against Eternal Sleep Disease; without Jinwoo’s unique cure, neither corporate resources nor medicine can save him. (Chapters 27–28, 49–55)

Relationships

• Jinho Yoo: His youngest son. Myunghan tests and disciplines him sternly, but privately celebrates every sign of independence and achievement.

• Kyunghye Park and Jinah Sung: Jinwoo’s family, whom Myunghan promises to protect if Jinwoo falls in the coming war.
• Secretary Kim: A trusted corporate aide who helps manage the chairman’s illness and discreet investigations.

Items

• Blank check: Offered to Jinwoo in exchange for a cure; it demonstrates both Myunghan’s resources and the limits of money.
• Hidden scrapbooks: Four private collections of articles about Jinho’s achievements in the rewritten world.
