The Major Shift: Jeon So-min’s Emotional Departure and the New Dynamic
The most significant cast change in recent years, outside of Lee Kwang-soo's departure in 2021, was the farewell of actress Jeon So-min (전소민). Her exit marked the end of a powerful era for the show.
Why Jeon So-min Left Running Man
Jeon So-min officially departed the show in November 2023, after six and a half years as a permanent member. Her agency stated that she wished to focus more on her acting career, which was the primary reason for her decision.
However, her time on the show was not without difficulty. Jeon So-min had previously spoken candidly about the emotional toll of appearing on the show, which included suffering from constant, harsh malicious comments from some viewers. This issue of online harassment is a sensitive topic that has been widely discussed in the Korean entertainment industry, and her departure brought it back into focus.
Her departure left a major void, as she was known for her eccentric, unpredictable, and often hilarious 'crazy' character, which provided a fresh dynamic to the long-running cast. Fans were left emotional, especially after her final episode, which celebrated her contributions.
The 2025 Strategy: Introducing 'Rental' and Guest Members
In the wake of Jeon So-min's departure, the producers of Running Man have opted for a new, flexible strategy rather than immediately naming a permanent replacement. This approach keeps the core six members intact while allowing for fresh, temporary energy. This strategy is a significant update for the 2025 season.
The Rise of the 'Rental' Member
The show has introduced the concept of a 'Rental Member' or 'Guest Member' who appears for a set number of episodes, effectively filling the seventh slot temporarily. This allows the production team and the audience to test chemistry without the pressure of a permanent commitment.
Notable 2024-2025 Rental Members:
- Kang Hoon: The actor gained significant attention during his appearances in 2024 and was mentioned as a 'Rental Member' for a period. His dynamic, particularly his comedic rivalry with Kim Jong-kook, was well-received by viewers.
- Ji Ye-eun (지예은): An actress who has been featured in several 2025 episodes. She has been listed in some sources as a 'Rental member,' indicating the show's continued use of this rotating cast strategy to maintain variety and a fresh feel.
This rotating cast model ensures that the show, which has been directed by various PDs (Producing Directors) over the years, including Choi Hyung-in in the 2022–2025 period, continues to evolve and surprise its audience. The show's ability to adapt its format and cast, moving from the original name-tag ripping focus to more complex games and character-driven missions, is key to its enduring global success and high topical authority in variety television.
Whether the show will eventually settle on a new permanent seventh member remains a major point of curiosity for fans. For now, the combination of the unbreakable core family—Yoo Jae-suk, Ji Suk-jin, Kim Jong-kook, Haha, Song Ji-hyo, and Yang Se-chan—with a rotating cast of talented 'rental' members is the formula that keeps Running Man one of the hottest and most-discussed variety shows in 2025. Fans can look forward to more international fan meetings and continued high-energy episodes throughout the year.
