For centuries, the aftermath of the Dragon War has caused harm to the lands. In particular, the Hiver kingdom remains in an unnatural winter due to its unique environment and remote location. Despite this, Hiver has managed to maintain peace for a long time. Princess Sofia, who is set to inherit the throne, feels uncertain about her leadership abilities and wishes to explore the outside world to learn more about her people's way of life while keeping her royal identity concealed. A Knight of Imperial Guard requests permission from the king on behalf of Princess Sofia to attend a "Canary Kindergarten" as a teacher under the knight's protection. The king, in his benevolence, grants Sofia this opportunity.
