MBC bought the rights to the comic strip for their adaptation, which was to star Lee Seung-gi in the title role of Iljimae.

However he pulled out and was replaced by Jung, which makes him the third Korean actor to play the hero following Jang Dong-gun (MBC, 1993) and Lee Joon-gi for Iljimae (SBS, 2008).

[5] Iljimae (Jung Il-woo) was born out of wedlock and his father was a high-ranking noble official while his mother was a lowly servant.

With a heavy heart, he returns to his native land and unleashes his anger upon the ruling class to fight injustice and tyranny for the sake of the commoners.

Living an isolated existence and hiding his face behind a mask to be a hero to the people, in Iljimae's life there is one woman who reconnects him to the world: Wol-hee.
