Amarion, a knight from a poor northern kingdom, battles monsters for survival. She is suddenly proposed to by Grand Duke Mort, nicknamed the "Walking Death," and accepts due to the generous dowry it offers her homeland. On their wedding night, he makes an unusual request: she must stay awake by his side while he sleeps, with the option to kill him if the burden becomes too great. As the nights pass and Amarion struggles to stay alert, the duke's behavior becomes increasingly gentle. Eventually, he asks her for something personal, signaling a shift in their relationship.
