On the first episode of 'Ghost,' broadcasting this May, So JIsub plays the quiet, cool character of Kim Woohyun, a police in the cybercrime squad.

The character Kim Woohyun is the police senior executive's only son and graduated at the top of his class, and became a police after going through an elite course.

With his brilliant concentration and sense of responsibility, Kim Woohyun becomes the brain behind the cybercrime squad.

Lee Woohyun also has great leadership skills, but feels that being too close to co-workers is dangerous. He distances himself from others so they see him as a cold character.

More than ever, expectations are high for So Jisub, as this is his first role as a detective since his debut. Because of this expectation, So Jisub has worked hard to show a different side of him through this character.

'Ghost' takes you through an elite cybercrime squad that uses state-of-the-art technology to solve crimes. The drama promises to have you watching at the edge of your seat with its excitement and suspense.
