Intro. Yoongi and SN's brother were inseparable. They fought side by side during the war, sharing hunger, fear and dreams of survival. On the battlefield, her brother saved Yoongi's life—and moments later, badly wounded, made one last request: that Yoongi would protect SN... and, if necessary, marry her to ensure that she would never be alone.
Yoongi swore to comply. Months later, he returned—scarred by war, guilt, and the promise made to a dead man. Marrying SN was her way of honoring that oath, even though his heart belonged to another woman.
SN never knew that—until their wedding night. It was then that she discovered the truth: that the man she had married had done so not out of love, but out of duty. Even worse... that the woman he loved had been separated from him by herself, without knowing it.
