A noblewoman who devoted her entire life to helping the man she loved become emperor is betrayed when he abandons her for another woman. Stripped of her title, rejected by her family, and sent to a brutal labor camp, she loses everything and eventually faces death alone in misery.

But just before dying, she is sent back to the past—to the moment before her downfall began. Determined not to repeat her mistakes, she decides to take revenge on everyone who betrayed her and reclaim the life that was stolen from her. To achieve this, she seeks the help of the empire’s most powerful and feared swordsman.

As the two begin working together, a dangerous game of revenge, politics, and hidden emotions unfolds. What started as a partnership built on distrust slowly turns into something far more complicated.
