South Korean actor Kim Yoon Sik has become one of Asia’s fastest-rising stars following the success of the hit BL (boys’ love) drama The Prosecutor’s Proposal.
Once a little-known actor who spent years auditioning for supporting roles, Kim Yoon Sik has now captured audiences across Asia with his compelling performance, striking visuals, and inspiring personal story of overcoming Tourette syndrome.
Kim Yoon Sik and co-star Park Si Woo recently appeared on the cover of Madame Figaro Hommes China, reflecting the drama’s growing popularity among Chinese audiences.
Despite ongoing limitations affecting Korean entertainment promotions in China, the magazine reportedly sold 32,000 copies within one minute of release and generated 22.6 million yuan in sales during its first day. The release also sparked massive online discussion, with related topics attracting nearly 100 million views and more than 100,000 comments, highlighting the pair’s growing influence.
Born in 1998, Kim Yoon Sik stands approximately 1.87 meters (6’2″) tall and studied Theater at Dongguk University. He made his acting debut in 2018 as the lead of the web drama MU:D Vol. 1 before taking supporting and guest roles in productions including: Trade Your Love, Hospital Playlist 2, Twenty-Five Twenty-One and I Am a Running Mate. He also appeared as a model in several K-pop music videos.
Before adopting his real name in 2024, Kim Yoon Sik promoted under the stage name Yoon Do Gun. Although he worked steadily for years, mainstream recognition remained elusive until 2026, when The Prosecutor’s Proposal transformed his career.
The Prosecutor’s Proposal tells the story of prosecutor Ju Tae Seon (Kim Yoon Sik) and investigator Lee Chae Ha (Park Si Woo), whose families are bound by a tragic past. Ju Tae Seon’s father was murdered, while Lee Chae Ha’s father was identified as the killer. As the two work together, long-held resentment gradually gives way to understanding and eventually, romance. Although the series is relatively short, viewers praised its strong storytelling and emotional performances.
Kim Yoon Sik earned particular acclaim for portraying a prosecutor who appears cold and composed on the outside while carrying deep emotional scars beneath the surface. Off-screen, however, colleagues describe him as cheerful, humorous, and surprisingly shy.
Beyond his acting ability, Kim Yoon Sik has become widely admired for his visual appeal. Fans frequently praise his:
- Tall 1.87-meter frame
- Fair complexion
- Bright smile
- Well-balanced physique
- Distinctive facial features, often described as having a mixed-race appearance
- Warm, optimistic personality
His popularity has grown at an astonishing pace. Before The Prosecutor’s Proposal premiered, Kim Yoon Sik had approximately 64,000 Instagram followers. Within a month of the drama’s release, that number had surged to more than 500,000.
One of the most inspiring aspects of Kim Yoon Sik’s journey is his openness about living with Tourette syndrome, a neurological condition that can cause involuntary motor and vocal tics.
Kim Yoon Sik has shared that he developed symptoms as a child. To help manage the condition and express his emotions, he immersed himself in a wide range of artistic and physical activities, including painting, playing the daegeum (traditional Korean bamboo flute), piano, hapkido and kendo. These creative outlets helped him regulate his emotions and gradually reduce the severity of his symptoms. Today, Kim Yoon Sik says his condition has improved significantly, allowing him to fully dedicate himself to the career he loves.
With the breakout success of The Prosecutor’s Proposal, Kim Yoon Sik has quickly established himself as one of South Korea’s most promising young actors.
His combination of acting talent, perseverance, and personal resilience has resonated with audiences across Asia, suggesting that his rise is only just beginning.
