Ready to Be Called the Poison Lady of the Cold-Blooded Emperor

A life that once vanished on the executioner's block. After turning back time, I chose a political marriage to the cold-blooded Emperor Cain, the man who destroyed my homeland. He pushes me away with, "If you plot against me, your head will fly." I expose the schemes of the inner palace, drink the poisoned cup myself, and prove my worth as his accomplice. A dangerous and sweet royal revenge drama that begins with being treated as a mere tool.
