On May 12, the official YouTube channel of Showbox released a new video featuring Jun Ji Hyun, Koo Kyo Hwan, Ji Chang Wook, Shin Hyun Been and Kim Shin Rok participating in a lighthearted quiz game ahead of the movie’s release.

During the segment, the cast members attempted to guess mystery words by asking the production staff various questions.

Koo Kyo Hwan immediately drew attention with his unusually enthusiastic questioning style. After first asking whether the item was sold at duty-free stores, he quickly followed up with another question before anyone else could react.

Seeing him continuously firing off questions, Jun Ji Hyun burst into laughter and jokingly scolded him: “How many questions are you asking right now? Why is he acting like this by himself?”

Her blunt but playful reaction instantly became one of the funniest moments in the video.

Koo Kyo Hwan responded with his trademark quirky humor, casually explaining:
“The staff member is a close older brother of mine, so I just asked.”

The exchange made both the cast and production team laugh.

At another point during the game, Jun Ji Hyun hilariously tried to stop Koo Kyo Hwan from making independent guesses without consulting the team. “Hey! Don’t do it!” she shouted, desperately trying to rein him in while the rest of the cast cracked up at their chaotic teamwork.

Fans online quickly praised the duo’s natural chemistry, with many viewers commenting that Jun Ji Hyun’s realistic reactions and Koo Kyo Hwan’s unpredictable personality created unexpectedly entertaining dynamics.

The upcoming film Colony, directed by Yeon Sang Ho, tells the story of people trapped inside a quarantined building during a mysterious infectious outbreak.

The thriller features a star-studded cast including Jun Ji Hyun, Koo Kyo Hwan, Ji Chang Wook, Shin Hyun Been and Kim Shin Rok.
Colony is scheduled to premiere in South Korea on May 21.
