The Secretary: Lee Seo Jin and Kim Kwang Kyu's First Ever Waterbomb... Behind-the-Scenes Stories of BIBI's Stage Revealed

As the SBS Friday variety show 'I Will Do Anything for You - The Secretary' is set to premiere on the 28th (Friday) at 11:10 PM, it will contain behind-the-scenes footage of BIBI's performance, who rose to become the 'No. 1 trending figure of 2026 Waterbomb Festival.'

Appearing as 'my star,' BIBI is the 'original Waterbomb goddess' representing South Korea's summer festival Waterbomb, and she garnered attention this year with her surprise performance. In the released video, unlike her glamorous appearance on stage, it was reported that BIBI showed extreme tension backstage, such as loosening her stiff body and having trembling hands.
