Intro
There was an ancient oracle in the kingdom.
The princess of the royal family must become a Saintess and be offered to the gods in the year she reaches adulthood. The people called it a blessing. A noble ritual to protect the kingdom. A sacred ceremony promising harvest, peace, and prosperity.
But only the royal family knew. Not a single Saintess had ever returned from that ritual.
"The ritual is in one month." At the priest's cold voice, the meeting room fell silent. The King and Queen could say nothing. They wanted to save Guest, but the prophecy that defying the oracle would bring disaster to the entire kingdom had been passed down for centuries.
In that moment of universal silence.
I'll do it.
The one who spoke quietly was the First Prince, Killua.
Oppa...!
It's not a princess they need, it's a Saintess.
When the Queen cried out that it was impossible and she couldn't lose him, he smiled calmly.
I'm just going in her place.
Guest has to live.
Being twins, the two looked remarkably alike. If he grew his hair, wore a dress, and learned the etiquette of a princess, no one would be able to tell them apart easily.
That night, Princess Guest puts on a maid's uniform and stays somewhere in the palace. And Prince Killua deceives the world to become the princess.
Because the brother chose to become the Saintess first, so that no one could sacrifice his sister.
...One princess is enough. The real princess has to survive.
A beautiful princess still resided in the royal palace. A princess who drank tea by the window, chatted, and attended balls. No one knew. No one knew that the princess was actually the kingdom's First Prince.
Guest lived in the palace wearing a maid's uniform, watching him from nearby.
She had to live with her identity hidden and her breath held. The coarse fabric she wore for the first time, the menial chores her hands weren't used to. Everything was foreign. But Guest's mind was only on her brother, who would be suffering in the palace.
In the palace, the 'princess' was smiling today as well. He adjusted the hem of his dress, greeted people gracefully, and maintained a composed expression even among nobles casting suspicious glances.
Only when night fell. Inside the firmly closed bedroom door, he took off the heavy wig. Long, braided silver hair flowed down to the floor. Loosening the corset that choked his neck, he let out a small sigh.
