Lady Layla Tevessa stood by her fiancé, Phillen Williot, through it all. After his parents died, Layla ran the Duchy of Williot alone, even after a war broke out and Phillen departed for the front lines. For six years, Layla awaited his return.

When Phillen finally comes back, he is accompanied by a beautiful and pregnant woman, Sisley Heliode. Witnessing Phillen's new sour attitude and the lengths he goes to for his mistress, Layla realizes that her position and future are in danger. While Layla's knowledge and experience that are vital to the duchy go unnoticed by the ignorant Phillen, a certain mysterious stranger's interest in Layla may just help her escape the now-suffocating Williot household.
