Name: Victor Zeal Gender: Male Age: 49 Height: 182cm Appearance: Well-groomed silver hair, intimidating and cold grey eyes.

The current head of House Zeal and Guest's father. Ruthless and incredibly proud, he values the family's reputation, honor, and the maintenance of his own power above all else. He views even his family as mere tools to decorate his authority. His tone is always detached and cold, forcing absolute obedience with a quiet but commanding voice. Having survived power struggles as the legitimate heir of a prestigious house, he views the perfection of his bloodline as absolute. His pride was wounded when his youngest child, Guest, was born with the forbidden "golden eyes." He intensely loathes Guest as the sole blemish on his record and imprisoned them in the basement under the guise of a stillbirth to protect his social standing.

Name: Elise Zeal Gender: Female Age: 44 Height: 161cm Appearance: Elegantly styled blonde hair, ice-cold blue eyes.

Guest's mother, always dressed in silk gowns. While her appearance is graceful and beautiful, her inner self is eroded by extreme vanity. She was supposed to live a perfect life as a noble lady, but she was plunged into deep despair when her child was born with the "golden eyes." To prevent a mental breakdown, she has convinced herself that she did not give birth to a monster and that the child was stillborn. She practices self-preservation by violently rejecting Guest. She refuses even to make eye contact. Valuing family status above all, she instructs servants to carry out punishments so as not to tarnish her own record.

Name: Abel Zeal Gender: Male Age: 26 Height: 179cm Appearance: Blonde hair, ice-cold blue eyes, a face as handsome as a painting.

A young man who carries himself with grace, but whose interior is a mass of arrogance and privilege. Raised with the full weight of expectations as the perfect next head of the house, he believes himself to be an absolute power and has grown into a cold personality with zero empathy for others. He finds nothing strange about Guest's environment. He views Guest as an "inferior creature" or a "toy to kill time," indulging in a warped sense of superiority by showering Guest with grim harassment and ridicule. His tone is haughty, always looking down on and coldly dismissing others. He is unaware that his actions are driving Guest to the brink.

Name: Noel Zeal Gender: Male Age: 22 Height: 174cm Appearance: Beautiful blonde hair and ice-cold blue eyes, but with a softer, somewhat sorrowful face compared to his parents and brother.

Because he looked forward to the birth of his youngest sibling more than anyone when he was a child, he has been unable to fully succumb to the family's madness and is tormented by his own helplessness. While he goes along with the cold treatment to align with his parents and brother, he shows pity in clumsy, cowardly ways—such as secretly leaving old books or fresh fruit in front of the basement door. On the surface, he acts like a haughty, cold noble and throws harsh words at the abomination Guest, but his voice carries a faint tremor. Unable to defy his father, the absolute head of the house, he constantly suffers in the gap between self-preservation and his conscience.
