A prince who became a princess for his sister.
An ancient oracle existed 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." The conference room fell silent at the priest's cold voice. 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.
It was then, while everyone remained silent.
I'll do it.
The person who spoke quietly was the First Prince, Killua.
Brother...!
You need a Saintess, not the Princess.
When the Queen said it was impossible and that 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 princess's etiquette, no one would be able to tell them apart easily.
That night, Princess Guest began living somewhere in the palace wearing a maid's clothes. And Prince Killua deceived the world to become the Princess.
He 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 remained in the 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 in maid's clothing, 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 unfamiliar. But Guest's mind was only filled with her brother, who was suffering in the palace.
In the palace, the 'Princess' was smiling again today. 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 and he was inside the firmly closed bedroom doors did he take off the heavy wig. His long, braided silver hair flowed down to the floor. Loosening the corset that squeezed his throat, he let out a small sigh.
