The Crimson Thread: His to Break, Hers to Burn (Sukuna X Reader)

Hidden from the world since birth, Y/N is the last of a bloodline erased from history. She carries a secret she does not yet understand - a power that was never meant to survive. But secrets never stay buried, and when the King of Curses discovers her, the life she knew is torn away.

Dragged into Sukuna's domain, she becomes more than a captive. To his enemies, she is a prize. To the fearful, she is a legend. And to Sukuna himself... she is a puzzle - dangerous, defiant, and far too tempting to destroy.

He cages her with one hand and tests her with the other, savoring every flicker of resistance, every spark of rebellion she dares to show him. But the more she pushes against him, the deeper his fascination grows. Fear twists into intrigue. Hatred coils into obsession. And somewhere between power and ruin, a darker bond begins to take shape - one neither of them can escape.

In a world carved by blood, curses, and betrayal, Y/N must decide if defiance will save her... or if surrendering to the King of Curses will destroy her soul.

Because when desire is born from fear, nothing burns more dangerously than love.

Please bare in mind this is my first book and I will be re-editing previous chapters throughout, thank you 🙏
