La villana que ha regresado jura castidad

Born to an old marquisal house with wealth and looks to spare, her one fatal flaw is terrible taste in men.
She pours her heart and fortune into a lowborn prince and helps him seize the throne—only to be betrayed for a distant relative.
Ready to prove how far obsession can go, she chooses poison… but the plan collapses, and she’s dragged to a brutal labor camp.

Amid plague and exhaustion, she wishes she could go back and slap some sense into herself—then wakes exactly at the afternoon tea when the poison was first slipped.
This time she swears off romance, starts fresh, and plots careful revenge on the betrayers.

To pull it off, she seeks the aid of the empire’s legendary “Sword,” openly confessing her regression.
He agrees to watch and help—yet as they live side by side, his cool gaze begins to change.
