Born in a village of northern nomadic tribes, the beautiful white-eyed girl, Eunhui, lives a peaceful life with the nomads, blessed with the divine ability of fire. However, Eunhui's tranquil childhood does not last long. Slave hunters from the powerful nation of Hae invade Eunhui's beautiful village, turning it into ruins and taking the white-eyed people as slaves. Eunhui, too, becomes a slave along with her tribe and steps into the distant land of Hae. On the brink of a slave auction, Eunhui, who has resigned herself to the meaning of life at the age of twelve, catches sight of a noble little girl looking at her with sparkling eyes. The girl, about nine years old, is undeniably beautiful and radiant, resembling the precious daughter of a high-ranking official from Hae. "Buy her for me." Eunhui gazes in shock at the young girl asking her nurse to buy her. Ignoring Eunhui's sharp gaze, the little girl meets her eyes directly and opens her small, adorable lips. "She's pretty. I want her." That was the beginning. The meeting between Eunhui and Haeru.
