Kim Gun Woo Reveals Real Relationship With 'The Glory' Actors

On April 9, "The Glory" star Kim Gun Woo made a special appearance in SBS TV's variety program "My Little Old Boy."

Unlike his character in the series, the actor has an introverted personality that makes it hard for him to interact with new people.

He told "My Little Old Boy" that he had a tough time during the filming of "The Glory," shocking the audience. Kim Gun Woo stated that he was "burdened" with his individual scenes with the Hallyu superstar.

Thankfully, Song Hye Kyo, whom the actor refers to as "Hye Kyo noona (older sister)," helped Kim Gun Woo a lot.

The restaurant conflict was the first scene that Kim Gun Woo and Song Hye Kyo shot together. Because of the pressure, the actor was evidently antsy.

"I was able to act with ease tanks to Hye Kyo noona, I," Kim Gun Woo shared. "She gave me acting advice before shooting and it boosted my confidence to act without hesitation."

Kim Gun Woo also expressed his eternal gratitude to the viewers who supported "The Glory" from beginning to end.
