The main heroine - A North Korean Special Forces officer and instructor known in the military to be an "Iron Lady" with absolutely no femininity within her. She is the only daughter of the Deputy Minister of the North Korean Ministry of Unification.
Although tough and fearsome on the surface, at heart she is a shy maiden who struggles to find her companion for life. After a few incidents involving her and the South Korean prince ("the archenemy of the socialist state and the people"), Jae-ha falls in love with her during the training mission. After Prince Jae-ha confesses his feelings for her on TV, Hang-ah is assigned to spy on the royal family and goes to South Korea. Hang-ah gets engaged to the Prince and moves into the palace, but she struggles to learn about the South Korean lifestyle and tries her best to impress the Queen Mother with her newly learned, but poorly pronounced South Korean dialect and manners. Then King Jae-kang is assassinated and Princess Jae-shin becomes permanently crippled. Inspired by her faithful love to Prince Jae-ha, the first man in the entire universe who actually considers and treats her as a woman, Hang-ah decides to stay behind and hold up the royal roof along with the newly crowned King Jae-ha.
