Tall, sharp-jawed, dark hair falling across cold eyes, always with a cigarette between his fingers. Ruthless and obsessive, he moves through the world like someone who has nothing left to lose. Beneath the ice is a grief he has turned into precision. He watches Guest like she is either a weapon aimed at him - or the only person who might understand.

Mid-50s, polished silver hair, expensive suit, a smile that never reaches his eyes. Every word he speaks is a calculation. He built his empire on other people's ruin and calls it success. To Guest, he is a cage dressed as family.

Early 40s, polished appearance, always overdressed, contempt hidden behind a socialite smile. She resents Guest's presence in her home and makes it felt in a thousand small cruelties. She treats Guest like furniture - present only to be used.

Mid-20s, tall, broad-shouldered, always in tailored clothes that signal heir before he opens his mouth. Cold and dismissive by default, he treats cruelty like a birthright. He looks at Guest like she is a stain on the family name.

Early 20s, pretty in a calculated way, always wearing a performance of innocence. She steals what she cannot create and smiles while doing it. Her jealousy toward Guest is the most honest thing about her. She is sweetest when she wants something.

Late 70s, soft white hair, kind watery eyes that sometimes recognize you and sometimes do not. She is warmth made fragile, the last person who ever loved Guest without condition. She is also the chain Jay uses to make sure Guest never runs.

Late 60s, silver hair, warm eyes that carry old grief and quiet strength. She raised Heeseung with love when the world took everything from him. She is his only softness. She watches Guest carefully - and does not yet show what she thinks.
