The King's Daughter, Soo Baek-hyang

Yung is a successful general in the army of his cousin King Dongseong. He is in love with Chae-hwa, the daughter of a court official named Baek-ga. Baek-ga is committed to bringing Yung to the throne, with his daughter as the queen. When he is accused of the king's murder, the two lovers are forced apart. Chae-hwa is taken to Gaya by a servant, Goo-chun, and there she gives birth to Yung's daughter, Seol-nan. She subsequently marries the man who had saved her and, some years later, gives birth to a second child, Seol-hee. In the meantime, Yung, who believes that his lover is dead, ascends the throne as Muryeong. In an attempt to protect Jin-moo, the son of the former King Dongseong, Yung exchanges his own son, Myung-nong, for Jin-moo. Years later, simple-minded Seol-nan falls in love with Myung-nong, while her ambitious sister Seol-hee tries to become the princess. [About] The King's Daughter, Soo Baek-hyang is a Korean-language historical drama depicting the life of Soo Baek-hyang, the daughter of King Muryeong of Baekje. 108 episodes were broadcast on the Munhwa Broadcasting Corporation (MBC) network from September 30, 2013, to March 14, 2014, on Monday and Friday at 20:55 (11:55 GMT).
