Initially the King's concubine, So-hwa is later elevated to the rank of Queen. But she becomes a pawn of the intense strife among warring political factions, and is stripped of her title and cast out of the palace in disgrace. Despite Cheo-sun's attempts to help her, she is sentenced to death. Cheo-sun carries out his orders by handing her the bowl of poison and he watches as the woman he loved all his life dies before his eyes. After her death, he looks after her son, Prince Yeonsan.
