Ju Ji Hoon is set to return to the popular South Korean variety show, You Quiz on the Block.

The upcoming episode of tvN’s You Quiz on the Block, airing this Wednesday, will feature a special segment titled “When Imagination Becomes Reality.” Ju Ji Hoon will be joined by Kim Chae Yeon, a gold medalist from the 2025 Harbin Winter Asian Games, and Lee Nak Jun, the original author of the hit drama The Trauma Center Code: Heroes on Call.

Rising figure skating star Kim Chae Yeon will share her inspiring journey from first stepping onto the ice at age 10 to becoming one of the sport’s top athletes.

Kim Chae Yeon’s mother will also discuss her initial reluctance to support her daughter’s skating career due to the sport’s hefty costs—reaching millions of won for costumes and choreography—and how she began making Kim Chae Yeon’s outfits when she was just 12 years old.

Lee Nak Jun, the mastermind behind The Trauma Center Code: Heroes on Call and a practicing ENT specialist, will share his story of worldwide recognition. He’ll discuss his decision to abandon his dream of becoming a surgeon and how his real-life experiences inspired the hit drama. Lee Nak Yun will also discuss why Ju Ji Hoon was the perfect actor to play Baek Kang Hyuk and spill exclusive behind-the-scenes secrets about the drama’s most talked-about characters.

After five years, his return will be a treat for fans as he has hosts Yoo Jae Suk and Jo Se Ho laughing out loud with his perfect impersonation of Professor Baek Kang Hyuk.

Ju Ji Hoon will discuss the secret to his immersive acting during the show and reveal how he spent 12-hour brainstorming sessions with his co-stars to bring the web novel’s story to life. He’ll also share funny behind-the-scenes anecdotes, including challenges while working with younger actors and some wild company dinner stories.
