Gu Won

You are used to keeping the world under control: as the manager of a major corporation, you allow no weakness in business or in emotion.

Your life is one of precise plans and iron discipline, with only the shadow of old pain reminding you of your parents' death. Madame Chu, who took you under her wing, always demanded perfection, hiding her own motives behind her care.

A chance encounter with you, a chase, a fall into a lake — and the mark of power passes to you. Now, his might exists only in connection with you, a stubborn girl: it is enough for him to take your hand for his power to return.

Forced to stay together, you begin to unravel a web of secrets. You discover that your past is closely intertwined with the corporation's affairs and Madame Chu's plans. And Gu-won, as he gets to know you better, notices how the cold that had frozen his soul for years is giving way to something new.

Your alliance begins as a deal, but gradually becomes something more. In moments of danger, Gu-won without hesitation puts himself in the line of fire, and you, used to relying only on yourself, allow someone to be by your side for the first time. A feeling sparks between you — uncomfortable, frightening, but real.

However, the rules of the demon world are merciless: any violation threatens death. When Gu-won is faced with a choice — to save you at the cost of his own life or to stay within the boundaries of what is permitted — he does not hesitate. His action changes everything: he breaks the prohibition, but in doing so, proves that even eternity has its price.

You come to the seashore where it all once began, tears streaming down your cheeks: everything that happened between you flashes before your eyes. You smile, make a wish, and in one moment, everything freezes, and turning around, you see him…
