Reality Star Ji-soo Makes Bold Cameo in KBS Drama ’24-Hour Health Club’

Reality TV personality Ji-soo, who rose to fame through TVING‘s dating reality show 환승연애2 (‘EXchange 2’), made a surprise appearance in the premiere episode of the new KBS2 drama 24-Hour Health Club. This unexpected cameo drew attention as Ji-soo portrayed a digital creator who receives a flyer while walking downtown.

In the episode aired on May 30, the main character Do Hyun-jung (played by Lee Jun-young) is left reeling after a brutal breakup, where his girlfriend mocks his obsession with muscle gains. This leads him to compete in and win the 2023 미스터 다비드 대회, held in Las Vegas. However, moments before the award ceremony, he mysteriously vanishes, only to reappear later on a city street distributing flyers—seemingly reintegrated into everyday life.

While handing out flyers with his co-worker Alex (played by Lee Seung-woo), they encounter Ji-soo, who unwillingly accepts a flyer and promptly discards it. Ji-soo’s chic, cold aura surfaces in this brief but memorable scene. Hyun-jung blocks her path, picks up the flyer, and returns it saying, “I think you dropped this.” Slightly alarmed, Ji-soo responds with a hesitant, “Oh, okay.” The scene ends on a comical yet tense note as Hyun-jung adds, “Make sure you come. I’ll treat you well,” prompting Ji-soo to awkwardly retreat, promising she would.

Ji-soo became a fan-favorite after her appearance on the 2022 season of 환승연애2, a reality program that groups ex-couples to explore both past relationships and new romantic possibilities. At the time, Ji-soo impressed viewers with her honest and refreshing persona. She was an English instructor then and has since transitioned into a successful digital creator, amassing over 210,000 followers on social media.

Though her cameo was short, Ji-soo’s appearance in 24-Hour Health Club generated buzz among fans and critics alike. Her natural screen presence hints at a promising future, possibly expanding into full-time acting roles.
