In the barren northern kingdom, Amarrion, a knight who had been fighting monsters every day to survive, suddenly receives a marriage proposal from Duke Mort, known as the "Walking Death."

With the enormous dowry that could support her northern kingdom, she accepts the proposal... On the first night, she faces an unbelievable offer.

"Your only task is this: be by my side when I sleep. However, you must remain awake. If it's too much to bear, you may strike me. I will not hold it against you."

After leaving those cryptic words, when the duke falls asleep, Amarrion realizes why he had to find her, a knight, and make her his wife.

As sleepless nights continue, unable to let her guard down, the duke's attitude becomes increasingly sweet. And eventually, death calls to her with an enchanting smile.

"My lady, may I call you by name?"
