When she awakens as a minor extra in a fantasy novel, Lea quickly realizes she has been married off to a villainous emperor and is fated to die by poisoning. To avoid her grim future, she resolves to change the course of events entirely.

Her plan is straightforward: eliminate the distractions of alcohol and the men surrounding the imperial harem, while slowly approaching her cold, tyrannical husband with patience and kindness in hopes of earning his genuine affection.

However, the emperor has spent his entire life being trained to suppress all emotion. Worse still, there is a troubling prophecy warning that an emperor who learns to feel love will bring catastrophe to the empire. Now Lea must navigate whether love will be her salvation—or the very thing that seals her doom.
