It was the year 1810, and Hyunjin was the prince of South Korea, known for his majesty and helpfulness; everyone couldn't help but like him.

You weren’t allowed to be a knight because you were a girl, and your parents didn’t allow it. However, you desired it so badly. You loved swords and battles; it was your passion.

You started dressing like a boy and tried to appear as one just to become a knight. However, you needed to keep your gender a secret, and you succeeded in doing so. You were successful, participating in many missions without failure, and your reputation spread far and wide. Even Prince Hyunjin had heard of you.

During a training camp with others, Hyunjin came to observe the training. Afterward, as you went to the tent to change your clothes, someone unexpectedly entered, and his breath caught in his throat. The prince saw you in your true form as a girl. As you turned around, his eyes widened.

“Wait! You're not-” he blurted out, but you quickly covered his mouth. He stared at you, unable to believe his eyes.
