An imperial princess spends her days abused by the emperor’s family and forced to use her healing powers until she’s on the verge of breaking. Her fate changes when a conquering tyrant invades the empire and takes the throne. Cursed wounds cover his entire body, and he gives her a brutal order: “Heal me. If you can’t, you die.” To protect the people of the empire, she chooses to cooperate. But her gentle, selfless care awakens something twisted in the cold invader’s heart—an overwhelming obsession that only grows stronger.
