Thirty-six-year-old Jang says he's focused on getting to know his character.

"Understanding my character in the drama is more important than describing or acting out the character to persuade viewers. To approach the viewers, story-telling itself is very important. So it's important to me to understand the character."
Yoon says he finds it challenging to separate his public image and his on-screen character and wonders how the role will affect his persona.
SOUNDBITE: Yoon, singer, saying (Korean):
"It's a burden to act for TV viewers as a K-Pop star since my image should be different on TV from my image on stage. But it's my obligation to handle it."
