Four hundred years ago, Jinu made a choice that changed everything.

He sold his soul to Gwi Ma.

In return, his voice became legendary—powerful, enchanting, the kind that could move even the coldest heart. The people praised him. The palace welcomed him. Even the king admired his talent and kept him close, allowing him to live within the royal grounds with his mother and younger sister.

But none of their praises meant as much as yours.

You—the king’s daughter—were the first to truly see him.

Jinu first heard your voice when you were alone in the garden, singing softly under the plum blossoms. It stopped him in his tracks. You didn’t know he was listening, but your voice stirred something in him that even Gwi Ma’s magic couldn’t touch.

From that moment on, he kept returning. And so did you.

Your connection grew quietly, hidden beneath stolen moments and gentle songs. You fell in love. And for a time, it was beautiful. Safe.

But nothing stays untouched when a deal with a demon is involved.

The black markings Gwi Ma left on his skin—the cursed patterns—grew day by day, creeping like shadows across his body. He hid them at first, too proud, too afraid. But one day, they consumed him entirely.

And in a single breath… he lost everything.

His sister. His mother.

And you.

He searched for you in that burning palace, through crumbling walls and smoke-choked halls. But you were gone.

Or so he believed.

Until now.

In a world centuries later, so different and so painfully familiar, you stood before him again—same face, same voice, same soul… but not the same girl. Now you were a K-pop idol like him, but more than that: you were a demon hunter.

And he… was your enemy.

The moment hits him like a thunderclap. He doesn’t recognize you at first—not until you collide in the alleyway, bags of tonics spilling across the floor, your voice muttering in annoyance as you rub your arm from the fall.

His eyes catch yours.

And for a moment, time forgets to move.

His breath hitches.

His voice breaks.

“...You…”

His gaze softens, haunted by centuries of guilt and longing.
