Ishtoria is a kingdom where blessed roses bloom. The main character, who hates the royal family for some reason, hides herself in a monastery and lives modestly.

The year she turns 20, she was invited by a man she was interested in to a national festival, which she had avoided up going to until that point. News of the second prince's return overlapped with the festival.

However, it was all a trap set to lure her to the royal palace.

The prince she hated calls the main character a 'savior' and offers her a game of chance: either she becomes his queen, or if she doesn't come to like him, he will take his own life the night before the coronation ceremony.

There are only 10 days left until the fateful coronation. Will the 'savior' who is trapped in the royal palace adorned with blessed roses bring salvation or ruin?
