Comedian Kim Sook revealed both the weight of her 32-year career and her warm humanity.

In episode 551 of the YouTube show Secret Guarantee, released at 7 p.m. on the 7th, Kim openly expressed her special affection for Sandara Park. Joined by Song Eun-i, the three displayed sister-like chemistry built on years of trust.

At the start of the show, Kim affectionately referred to Sandara as “my child,” a playful remark that nonetheless reflected her sense of responsibility toward younger colleagues. Sandara, the first celebrity to publicly declare herself part of the “Kim Sook line,” appeared on the show out of loyalty rather than promotion, further warming the atmosphere.

Born in 1975 and debuting in 1995, Kim Sook is now 50 and unmarried, yet she has long served as an emotional anchor for many juniors in the entertainment industry. During the episode, she naturally guided Sandara through stories from their time on MBC every1’s Video Star, sharing both struggles and moments of growth.

When Sandara recalled gaining eight kilograms during filming—sparking rumors about her health—Kim diffused the moment with her signature realism and humor. Sandara’s candid comment, “It’s better to meet occasionally,” drew laughter, highlighting their comfortable relationship.

Kim’s presence also stood out in the show’s signature segment, where topics ranged from Sandara’s iconic 2NE1 hairstyles and top three favorite songs to her youthful looks. Kim anchored the discussion with empathy and practical advice drawn from experience. A quirky question about what Sandara would grab first in a fire, along with Kim’s own “secret dating tips,” even surprised the production team.

Through this episode, Kim Sook once again demonstrated the responsibility and depth behind her humor. Her joking reference to Sandara as her “child” encapsulated why she has remained a trusted and beloved figure for over three decades.

Episode 551 of Secret Guarantee premieres at 7 p.m. on the 7th on YouTube.
