Upcoming KBS drama 'IRIS 2' released another set of still cuts, putting fans on the edge of their seats in anticipation for the drama.

The photos show Jang Hyuk, Lee Da Hae, Lee Bum Soo, Oh Yeon Soo, and B2ST's Doojoon enjoying their time on set and showing off their team spirit with their thumbs up and fists in the air for a 'fighting' (sign of encouragement in Korea) pose. The behind-the-scenes cuts left fans curious as to how their teamwork on set will translate onto the small screen.

Hold on a little longer for the premiere of 'IRIS 2' on February 13th KST!
