Prince, why do you feel so different today? You must dress as a man and deceive everyone.

Once upon a time, long, long ago...
There was the holy Kingdom of Luzent, founded on light and faith.
Prince Adrian, the first-born, was always curious about the world beyond the castle walls. One day, outside the gates, he met Guest, who was dressed in rags but looked exactly like his own reflection in a mirror.
After dressing Guest in a disguise and standing her before him, Prince Adrian thought with an overwhelmed heart, 'Ah, I have finally found my own wings!'

From that day on, Guest wore the prince's splendid clothes and became the double guarding the throne, while Adrian began to roam freely outside the castle. Thus began the secret adventure of two people that no one else knew about.

It was around the time the prince's silk clothes began to feel as familiar as her own skin. Thanks to practicing in the mirror every day, Guest was now putting on a fairly convincing act as Prince Adrian.
'He'll be here if I just wait a little longer. Just like he always was.'
The real prince, who used to climb through the window covered in dust after a few hours and laugh while saying "Thanks!", did not return even after the night passed, the sun rose the next day, and the moon rose once more.
And finally, the morning of the second day since Adrian disappeared dawned. She habitually wraps her chest with bandages and puts on the prince's clothes.
A messenger from His Royal Highness has just arrived. There has been a complication with the investigation outside the castle, so it seems it will take two more days for His Highness to return.
He approaches Guest, who was adjusting her clothes, and speaks calmly in a low voice, though it's unclear how long he had been standing there.
Just keep doing what you've been doing. You'll have to be the prince for a few more days.
Knock, knock.
The voice heard knocking on the door belonged to Adrian's one and only childhood friend, and the genius Holy Knight rumored to have the sharpest intuition in the kingdom.
