Lee Hyun Wook has opened up about playing the son of Kim Kang Woo in KBS2's upcoming historical drama Sword & Silence, despite the two actors having only a seven-year age difference in real life.

On November 12, the cast attended a production press conference at The Link Hotel in Sindorim, Seoul, where Lee Hyun Wook shared how Kim Kang Woo helped make their father-and-son relationship believable on screen.

Born in 1985, Lee Hyun Wook, 41, plays Kim Beop Min, who becomes King Munmu, the 30th ruler of Silla. Meanwhile, Kim Kang Woo, born in 1978, plays his father, Kim Chun Chu, also known as King Taejong Muyeol, the 29th ruler of Silla.

Despite being only seven years apart in age, Lee Hyun Wook revealed that their working relationship felt surprisingly natural because of Kim Kang Woo's support during filming.

“He prepared so thoroughly and created the right atmosphere on set,” Lee Hyun Wook shared.

He explained that although some people questioned whether the two actors looked old enough to portray father and son, Kim Kang Woo made him feel comfortable in their roles.

“People said our age difference didn't seem that big, but on set, he took care of me like a father and helped guide our emotional exchanges. That really helped me a lot,” he said.

Lee Hyun Wook also praised Kim Kang Woo for helping him understand the complicated relationship between their characters.

In the drama, Kim Beop Min initially struggles to accept his father's political beliefs and decisions. However, their relationship develops as he begins to understand his father's perspective.

According to Lee Hyun Wook, Kim Kang Woo helped him express those emotional changes naturally throughout their scenes.

“He helped me understand and follow those emotional changes. Our chemistry was perfect,” the actor shared.

His comments drew attention to the actors' ability to portray a convincing father-and-son relationship despite their small age difference.

Meanwhile, Sword & Silence follows the struggles of leaders during Korea's Three Kingdoms period as they face political conflict and wars while pursuing victory.

With Lee Hyun Wook and Kim Kang Woo portraying two important figures in Silla's history, their father-and-son relationship is expected to be one of the drama's key storylines.

Sword & Silence is scheduled to premiere on November 14 at 9:20 PM KST on KBS2.
