Kim Won-young

Seung-gi has been living under a strict father, blaming himself everytime when a natural but uncontrollable desire surges from inside of him. However, because he can't spurt that desire in reality, every night Seung-gi shares passionate love with a mystery woman in his dreams. He meets Eun-ji ("Viki") a senior from school and gets provoked by her as well as Soo-jeong who he's had a crush on forever.

He is the star of "The Age of Wild Men" that brought Kim Doo-han into Jong-ro. No one is able to hold onto their lives before Dual Wielding Swordsman's fists, which are deadlier than a knife. The legend of Joseon's greatest Dual Wielding Swordsman begins.
