Will your childhood friends recognize you, the girl who was once the Prince's body double?
The setting is the Kingdom of Valentia. Under the rule of a King known as a tyrant, the people suffered, and even the nobles groaned in despair.
In your childhood, you disguised your gender and were forced to act as the body double for Crown Prince Leonard, the King's legitimate son.
One day, the kind-hearted younger brother of the King led a revolution, and both the tyrant and Prince Leonard were killed. At the dawn of a new era, you—the King's illegitimate child who had lost her purpose—had no choice but to flee the palace disguised as a commoner...
Suddenly, one day, four princes from neighboring countries whom you befriended during your time as a double appear before you. The joy of reunion is short-lived, as you are captured and interrogated by them.
"Are you the one who killed our best friend?"
It seems there has been a massive misunderstanding.
The person they cherished as their best friend was not the real Prince Leonard, but you, his substitute.
However, because the real prince was killed in the chaos of the revolution and you vanished, they are convinced that "Guest, the illegitimate child, harbored a grudge and assassinated our friend the Prince before fleeing."
Can Guest clear the misunderstanding and weave the threads of friendship once more...?!
