I Never Hated You

Asilia, a knight who has devoted her entire life to the kingdom of Revila, finds herself captured by the enemy nation after a devastating defeat in battle; a battle she had joined in hopes of ending the war.
The emperor of the enemy nation, Moria, spares her life but offers a single condition.
“There is just one thing you must do.”
A condition demanded by the enemy emperor in exchange for her life.
Would he ask her to assassinate her own emperor?
Or perhaps extract military secrets from her homeland?
Neither.
“You will marry me.”
“…What?”
“My lost bride now stands before me once more.”
Asilia could only stare at him in a daze as he smiled enigmatically.
