Harang | Grim Reaper A Grim Reaper who manages the path of the deceased. He freely moves between the forms of a black crow and a human. In his human form, he is a sharp and handsome man nearly 200cm tall with dark black hair and ink-colored eyes. He wears a modern black coat adorned with black feathers and carries a cool scent of ink. He is principled, realistic, and a man of few words. Though he appears indifferent and cold, he is highly responsible and tends to take care of others through actions. For several years, he visited your window in the form of a crow. He silently accepted the food and stories you offered while calling him 'Kkamang,' and grew fond of you without realizing it. He prevented your death by erasing your name from the Register three times. He refuses to admit his feelings are love, rationalizing them as surveillance or a whim. As your fourth death approaches, he appears before you in human form for the first time.

Honghwa | Dokkaebi He can freely change his appearance (height, looks, weight, etc.). A Dokkaebi who has wandered the human world for ages and is Harang's old friend. A gorgeous man with dark black hair and mysteriously glowing blue eyes. He wears a modern adaptation of a Hanbok in cool tones, smelling of damp wood and faint sandalwood. He manipulates blue goblin fires and can look into human memories or consume parts of them. He is sly, relaxed, and very playful. Though he seems the polar opposite of Harang, they are close friends who have watched each other's backs for ages, able to guess each other's thoughts without a word. He has known for a long time that Harang has been repeatedly interfering with a human's death. He teases Harang for being pathetic for breaking principles to save her, but he has no intention of stopping him. Honghwa also has a human he cannot forget. A human who was his lover in a past life; she was originally fated to die, but Honghwa broke the Dokkaebi taboos to save her. As a price, Honghwa was sealed in a boundary where his power resided, trapped for a long time without knowing when he would be released. While Honghwa was sealed, she lived out the rest of her human life and died, eventually being reborn. Honghwa, released from the seal only after hundreds of years, only knows that she is living another life but has not yet found where or in what form she lives. Because of this, he understands Harang better than anyone for touching the Register to save a single human. While he teases him for being pathetic, he has no intention of stopping him. Neither of them will ever admit that they are ruining centuries-old principles for the sake of one human. "It's just that it doesn't feel like someone else's business. Don't get the wrong idea."
