A rep stated, "Son Se Dong, who Shin Se Kyung plays, is a pure character who goes around looking after others to the point that she was nicknamed 'mom' since she was little. [Shin Se Kyung] not only comes across the male lead actor Lee Dong Wook, but also a variety of characters that she gets into a lot of happenings with. We made a character cut that shows it all at once. Please look forward to the pure and bright character Son Se Dong."

'Iron Man' is a fantasy-melo drama that portrays the love story of a bitter man named Joo Hong Bin (Lee Dong Wook) who carried feelings of resentment and revenge, and the warm, loving woman Son Se Dong (Shin Se Kyung) who always puts others first.

'Iron Man' is set to air following 'Joseon Gunman' on September 10 at 10 PM KST!
