Kang and Hwi, the two princes of Joseon Dynasty, were born a year apart and grew up like twins. Kang, the older brother and the second son of King Sejong, has been underestimated from the royal family because of his younger brother, Hwi's outstanding performance. Hwi is known as the greatest artist of the time and Kang was always jealous of his brother. One day, the two young princes decided to play hide-and-seek with their maids. In the middle of the play, Kang found out that all of the maids were only looking for Hwi. With anger, Kang called Yeon-I, who is the maid of Hwi, and demanded her to be his maid. When Yeon-I refused Kang's demand, Kang pushed her into a pond and watched her dying.
