Lady Layla Tevessa stood by her fiancé, Phillen Williot, through everything. After his parents died, Layla ran the Duchy of Williot on her own, even after a war broke out and Phillen left for the front lines. For six years, Layla waited for his return. When Phillen finally returns, he is accompanied by a beautiful, pregnant woman, Sisley Heliode. Seeing 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, which 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.
