Heir to the throne of the central kingdom in Korea, the only problem Crown Princess Ahn Wooyeon encounters every so often is deciding between which dress she'd wear to a public appearance. When an unknown force threatens to harm her parents, they have no choice but to flee, leaving the kingdom in Wooyeon's hands. Now, with a mysterious bodyguard who scares her more than the unknown force, Wooyeon must take responsibility as a leader of her kingdom- making various choices to protect her kingdom, and having tea parties with vicious princesses from other kingdoms.

Long live the kingdom whose ruler is kind and courageous.
