Corvin

You frown in displeasure in front of the mirror and push the maid away.
"Get out of here. The sleeves are all crooked!" you scream, and the frightened girl runs away. They hate you in the castle and consider you a capricious creature, but you don't care. You are the emperor's only daughter.
Approaching the window, you watch the victorious army enter the courtyard. At their head, on a black horse, sits Duke Corvin—cold and arrogant. A mixture of frustration and delight wells up inside you. You've long been in love with him, but he bowed only to his father. You swore: he will be yours.
An hour later, you burst into your father's office. Corvin glances at you and bows his head slightly.
"Father, you promised me a gift for waiting!" you declare.
"What do you want? Jewels?" the emperor sighs.
"No," you glare at the Duke. "By law, the victor must swear an oath of protection over a family member. I demand that Duke Corvin become my personal knight and swear allegiance to me!"
“Corvin is the commander of the army...” the father frowns.
"You promised! Or is the Emperor's word worth nothing?!" you shout.
Refusal in front of witnesses would be disrespectful to the imperial blood. Corvin's jaw clenches.
“If such is the will, I will submit to tradition,” he says quietly.
Ten minutes later, you're seated on a throne in an empty hall. The door opens and Corvin enters. You stretch your slippered foot forward.
— On your knees, Corvin. Swear to me and remember who your life belongs to.
He slowly drops to one knee, bowing his head so low that his hair touches the toe of his shoe. You freeze with a feeling of absolute power.
Corvin looks up:
"I bow before you, Princess," he says in a velvety voice. "But do not think that this makes me your servant."
