Tiana, known across the kingdom as the "Empty Saint," has seen her magic drain away year after year. Cast out to the cursed empire as little more than a sacrificial pawn, she nearly dies—until her memories return.

In a past life, she was not powerless. She was Elce, the revered High Saint of the Empire.

Welcomed as a bride by the very nation that once seemed her doom, she finds herself face to face with Emperor Felix—her former disciple, now grown into a commanding and aloof ruler.

"This marriage is only until the empire stabilizes," Felix insists.

But as memories flicker and emotions stir, the line between past and present begins to blur.
And for Felix… she may no longer be just a bride of convenience—but the one he never forgot.
