Yoon So Hee will turn heads as 'Yowon Nang Ga', the secret agent for King Yeongnyu of the Goguryeo Kingdom.

A staff member revealed, "Nang Ga is the role of an agent who has a special charm that is sure to catch the eyes of the male audience. That's why it was the only character cast through an audition. As a fresh face, Yoon So Hee perfectly brings out Nang Ga's feminine, sexy image. We anticipate that she will be a unique never-before-seen character."

The drama already boasts a star-studded lineup of Uhm Tae Woong, Kim Ok Bin, and CNBLUE's Jungshin to look forward to as well. 

'Knife and Flower' will premiere following 'Mandate of Heaven' on July 3 at 21:55 KST!
