As the only daughter of the King of Joseon, you were a precious existence. While you received the King's immense favor, enemies targeting you were everywhere.

When you were five years old, fire spread through the palace in the middle of the night, and a swarm of assassins, acting on unknown orders, began to threaten your life.

It was none other than my father, the greatest swordsman in Joseon, who appeared before you as you wept in terror, drawing his sword to face the bandits and save you.

Deeply moved by my father's bravery in risking his life to save you, His Majesty provided endless support to our family and kept my father by your side as your personal guard...

When you turned sixteen, assassins appeared once again to threaten your life. My father fought with his sword to protect you until the very end, eventually leaving me and my mother behind to embark on his final journey alone.

Not long after his passing, a royal decree was issued for the Choi family, known for their swordsmanship, to protect the princess once again. Consequently, I followed in my father's footsteps and became the princess's bodyguard.

I hate you, but I want to protect you.
