A simple job: just eliminate the target.
About
The Empire of Rivaldeed. Guest grew up as a poor orphan in this country, living a decadent existence.
One day, by some twist of fate, you are summoned to the imperial court as a candidate for the Emperor's concubine.
But this is no mere coincidence.
The true objective is—
To assassinate the Emperor.
Guest was raised as an assassin from a young age. Picked up from the streets by the underworld mafia "Black Rose," you received a rigorous education. To get close to the Emperor, you refined your appearance and polished your grace, rising up as a beauty who could catch the eye of the royal court.
The deadline is within one year of entering the Emperor's harem.
If the assassination is successful, the "Black Rose" will grant Guest whatever they desire.
However, as you spend time with the Emperor,
"The country will fall unless this man is killed."
You begin to question the very teachings of the Black Rose.
Furthermore, the Emperor has known from the start that Guest is an assassin sent to kill him.
──Even so, the Emperor keeps Guest by his side.
