Kim Yoon Seok has named Koo Kyo Hwan his current favorite junior co-star, despite having worked with major Korean actors including Ha Jung Woo, Kang Dong Won, Ju Ji Hoon, and Jo In Sung.

The veteran actor made the playful confession during a press conference for his upcoming mystery film White Blast on November 12 at CGV Yongsan I'Park Mall in Seoul.

When asked where Koo Kyo Hwan ranked among the many younger actors he had worked with, Kim Yoon Seok gave an amusing answer that drew laughter.

“Right now, Koo Kyo Hwan is my No. 1. But at the press conference for my next project, I'll probably say Kim Seon Ho is No. 1,” he joked.

The comment referred to his upcoming drama May the Congressman Protect You, where he will work alongside Kim Seon Ho.

Although his answer was humorous, Kim Yoon Seok also expressed genuine admiration for Koo Kyo Hwan's acting.

The two actors reunited in White Blast after previously working together in Escape from Mogadishu.

In the new film, Kim Yoon Seok plays Gap Soo, a stationmaster preparing for retirement, while Koo Kyo Hwan portrays Hyun Taek, the employee who arrives to replace him.

The mystery unfolds when the two discover an unidentified body at a rural train station isolated by heavy snowfall.

Speaking about their collaboration, Koo Kyo Hwan praised Kim Yoon Seok for being a supportive senior actor.

“I was amazed every moment. It felt special to exchange lines with him throughout filming,” he shared.

He also recalled a meaningful moment when he was nervous about filming a monologue.

“I remember being nervous before my monologue scene, and he told me, 'Today is your day.' He was my biggest supporter and someone I could really look up to,” Koo Kyo Hwan said.

Kim Yoon Seok responded with praise of his own, describing Koo Kyo Hwan as someone who appears gentle but can deliver surprisingly powerful performances.

“There were moments when he showed an overwhelming strength. When I saw his ability to look straight into someone's heart, I felt a real thrill,” he explained.

The veteran actor added that the experience made him want to work with Koo Kyo Hwan again.

Their mutual admiration has become one of the talking points surrounding White Blast, particularly as Kim Yoon Seok continues to work with different generations of Korean actors.

Meanwhile, White Blast, directed by Hong Eui Jeong, is scheduled to open in South Korean theaters on November 18.
