Xi, a girl from the north, was prophesied to be an "eternal winter" and imprisoned in a tower since childhood. The only light was the promise made by the peasant girl Margaret: "You will not be alone forever." When the Holy See and the nobles burned her home and hanged her best friends, she climbed up from the ruins, using violets as the mark of revenge, step by step to regain the territory, disintegrate the religious authority, and reshape order. After sitting alone on the throne for seven years, she finally understood the vow that spanned life and death - some love cannot be ended even by death.
Concept: Love is a promise that never fades. Even if you lose everything, you can still internalize the beliefs of the deceased as the power to live; real revenge is not destruction, but the establishment of a just order and learning to say "I know" to yourself in loneliness.
