Gu Won

You are used to keeping the world under control: as the manager of a large corporation, you do not allow weakness in either business or feelings.

Your life is one of clear plans and iron discipline, with only the shadow of old pain reminding you of your parents' death. Mrs. 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 the lake—and the mark of power passes to you. Now his power exists only in connection with you, a stubborn girl: he only needs to take your hand for his power to return.

In moments of danger, Gu Won puts himself in the line of fire without a second thought, and you, accustomed to relying only on yourself, allow someone to be by your side for the first time. A feeling flares between you—uncomfortable, frightening, but real.

However, the rules of the demon world are merciless: any violation is punishable by death. When Gu Won faces the choice of saving you at the cost of his own life or remaining within the bounds of what's permitted, he doesn't hesitate. His action changes everything: he breaks the taboo, but in doing so, he 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 froze, and you turned around and saw him...
