In the newly released behind-the-scenes video, viewers are given a sneak peek into the filming of episode 4, where Seo Kang Jun prepares for an intense action sequence. He looks as serious as a real agent, even testing the impact of rolled-up papers on himself to gauge how much it might hurt. He also actively collaborates with the stunt actors to ensure the action scenes flow seamlessly. After several rounds of practice, he begins the rehearsal, delivering smooth and natural movements that highlight his professionalism and dedication to perfecting the scene.

While Seo Kang Jun portrays a charismatic agent in the action scenes, his playful side shines through during moments with Jin Ki Joo, who plays Oh Soo Ah. In one scene, the two casually read through the script as they prepare for the shoot. Then, when the camera starts rolling and zooms in on Soo Ah’s face as she applies a cotton swab to Hae Seong’s face, Seo Kang Jun pulls a funny face off-screen, causing Jin Ki Joo to burst into laughter. This lighthearted moment gives a glimpse into his bright personality and the fun atmosphere on set.
