Seo Kang-joon (right) and Shin Ki-joo play a duet in "Undercover High." The 31-year-old Seo Kang-joon returns to the screen after three years, with his first post-military Korean drama "Undercover High" having concluded last weekend. When asked if anything interesting happened during his time in the army, he candidly stated, "There wasn't a single moment that was fun." He mentioned that during a night march at the training base, the temperature dropped to minus 22 degrees, and the heat inside the helmet condensed into vapor, causing icicles to form on the visor—a scene that left a deep impression on him and remains vivid in his memory.
Seo Kang-joon recalled undergoing a five-day, four-night extreme cold training in temperatures of minus 13 to 14 degrees, saying, "At that time, I really felt the sense that 'as long as you persevere, you can get through it.' It was cold and I was hungry, and that memory is still profound to this day." Regarding his collaboration with Shin Ki-joo in "Undercover High," which has been the hot topic champion for six consecutive weeks, Seo Kang-joon shared his thoughts at the end of the series, expressing emotionally, "This work is very significant to me because it allows me to meet everyone with a new image after my military service. The character's style is completely different from what I've played in the past, and I am very happy to portray this 'Cool Guy.'
Shin Ki-joo also mentioned, "During this time, I received a lot of support and love, and I'm really grateful. I want to act a little more; it feels like the 12 episodes went by too quickly." The entire 12 episodes of "Undercover High" are currently available on friDay Video.
