Two princesses are born with different fates. Princess Ja Myung is burdened with the destiny of saving her nation, Nakrang. Unlike her half-sister, Princess Nakrang, who enjoys a life of comfort and privilege, Princess Ja Myung's life is marked by hardship. The two sisters, who were born on the same day, both fall in love with Ho Dong, the prince of Goguryeo. The intelligent and handsome prince is revered by the people of Goguryeo as the reincarnation of the nation's founder, Ju Mong, due to his exceptional archery skills. Prince Ho Dong aspires to expand Goguryeo into a great empire by conquering Nakrang but is torn between the ambitious and powerful Goguryeo army and the sincere and ardent love of Nakrang and Ja Myung. The survival of an ancient kingdom depends on the love triangle between one who can sacrifice everything for the person she loves, one who can hurt the one she loves to save her nation, and one who does not know how to love, having never known the love of a parent.
