Three years after her kingdom fell to a bloody revolution, Princess Lien remains locked in a subterranean prison, forgotten by the world—until an imperial decree forces her into a political marriage with Duke Rishian of Roche-Noir. Long accustomed to retreating into her own inner abyss whenever the world treated her as a cursed relic of a ruined dynasty, Lien finds an unexpected refuge in her new husband. Through Rishian’s unwavering devotion and solidarity, she learns to confront her true self and break free from the chains of her past. Together, they discover that trust and promises are far stronger than cruel fate, and that two lost souls can become each other’s most brilliant homecoming.
