Broadcaster Kim Sook and actor Koo Bon Seung, who recently found themselves at the center of marriage rumors, shared a heartwarming onstage moment that reignited public interest.
In newly released footage from the 10th Anniversary Vivo Show concert on YouTube channel Vivo TV, Kim Sook and Song Eun Yi celebrated the milestone with laughter and surprise guests. Kim invited Koo Bon Seung, her rumored on-screen partner from the variety show Seeking Old Encounters, to the event.
To everyone’s astonishment, Kim appeared in a wedding dress as the concert began, prompting fellow performer Hwangbo to burst out laughing from the audience and exclaim in disbelief.
Koo, visibly caught off guard, admitted he had no idea about the dress during rehearsals. When he joined her on stage, the two exchanged a warm embrace. Kim jokingly asked whether she should keep or toss the gown, and Koo playfully replied that she should hold onto it for now, drawing laughter from fans.
Their affectionate exchange and past chemistry have continued to fuel speculation about their relationship, especially after comedian Park Myung Soo teasingly named October 7 as their supposed wedding date, keeping the playful rumor mill spinning.
