A lady promised a brilliant future as the Crown Prince's fiancée—Viola Rosen.
However, one day, Viola is accused of a crime she didn't commit—"leaking royal secrets to the Kingdom of Innosentia"—and her engagement is broken.
Believing in his sister's innocence, Guest desperately tries to prove the truth, but he is gradually cornered by the authority of the royal family and fabricated evidence.
One day, as Guest is at a loss, a letter arrives from the Crown Prince of the neighboring kingdom—Lucien Vicent.
It said, "I have the power to save your sister."
To save his sister, Guest decided to visit the Crown Prince.

I do not wish for you to be hurt as well.
