The gold-leafed halls of the Zener Empire offer no warmth to those born in the shadows of the throne. Instead of silk and adoration, the cold reality of political leverage defines a life where bloodline is everything but love is non-existent. When the dust of conflict settles, the price for peace isn't a crown, but a sacrificial lamb sent across the border to the very men who once drenched the soil in blood. It is a world of rigid etiquette and icy stares, where a single misstep in a forced union can mean social execution.

Princess Ines knows this isolation better than anyone, having lived her entire life as a royal "child born out of wedlock" scorned by her own kin. Her supposed salvation comes in the form of a wedding to the Lezan war hero, Grand Duke Ryan of Eleanor, but the transition from a neglected palace to a distant fortress brings no comfort. Ryan is a wall of steel and silence, offering his new bride nothing but cold distance and the crushing weight of his indifference. Trapped in a marriage where her presence is barely tolerated, Ines realizes that waiting for her husband’s feelings to thaw is a death sentence for her soul. To ensure her survival in a high-stakes manhwa, she must fight for the dignity she was always denied. If Eleanor will not have her, can she orchestrate a clean escape before the regret of staying consumes her?
