Veteran actor Yu Oh Seong sat down and shared his feelings on his performance in the recently concluded spy agent drama "The Veil," as well as his thoughts on his co-workers.

Yu Oh Seong on His Character in 'The Veil'

MBC's "The Veil" followed the tragic story of Han Ji Hyuk (Namgoong Min), the top spy agent of the National Intelligence Service (NIS), who returns to seek revenge after a traitor drops him into the abyss.

In the drama, Yu Oh Seong took on the role of Baek Mo Sa, the villain who had a surprising relation to Han Ji Hyuk's partner, Yoo Je Yi (Kim Ji Eun).

He revealed that he didn't read the script before the drama's filming. Yu Oh Seong reasoned, "When I first met the director, I was given the role of a back-up. Of course, there was the thought that it would work. So when I was chosen to play the part, the pressure came in but I had a lot of faith in the director."

He also shared that even the other drama actors found out his casting late, "I filmed the first scene and went to a self-production report. After seeing it, the other actors were clueless that I had been chosen to play the role of Baek Mo Sa. I was quite embarrassed."

Yu Oh Seong described his character as a "lonely person" who was manipulative and violent. Despite being similar to Han Ji Hyuk, Baek Mo Sa was a selfish criminal. He said, "Baek Mo Sa was quite sentimental. However, he is a strong man who isn't scared of anyone, not even the higher ups, so I decided to concede my emotions [even when everyone was crying while filming an emotional scene] to play the part."

The actor is a veteran with many years of acting experience, and it is not a surprise that everyone around him admired his acting prowess.

However, Yu Oh Seong expressed his dislike for the constant admiration for him, saying, "An actor has to act. That's how I live. I'm grateful for everyone's touching messages, but acting is something I must do."

Yu Oh Seong was quite delighted to work with fellow amazing actors. He showered compliments to his co-stars, especially Namgoong Min and Kim Ji Eun, who led the series with their abilities.

He said, "Everyone's character suits their actors but I think Namgoong Min and Kim Ji Eun gave the greatest acting performances as they both finished with just one shot. You have no choice because you are already great actors."

In addition to that, Yu Oh Seong's character was unexpectedly related to Kim Ji Eun's character. In the later part of the drama, it was revealed that Baek Mo Sa fathers the beautiful and determined top agent Yoo Je Yi.

Yu Oh Seong continued to praise the actress and said, "Kim Ji Eun and I don't usually talk during emotional scenes but she is really good at acting. It is something we do better than most people. We really had great synergy that comes out naturally."
