[Sports Seoul | Reporter Choi Seung-seop] Actor Yoon Byung-hee has shared a warm behind-the-scenes moment that stands in stark contrast to the tense on-screen dynamic.<\/p>\n

On the 12th, Yoon posted a photo with IU on her social media, captioned, “CEO Seong Hee-ju, I’m actually a fan.”<\/p>\n

In the released images, the two stand side by side on the drama set, flashing V signs and smiling brightly.<\/p>\n

In the currently airing MBC Friday\u2013Saturday drama “21st Century Grand Lady,” Yoon makes a special appearance as the head of PR for Castle Beauty, the company run by lead character Seong Hee-ju (IU). Onscreen, their relationship plays out as a strict boss-and-subordinate dynamic: Seong Hee-ju\u2019s sharp rebukes leave Yoon visibly rattled \u2014 a contrast that resonated with viewers.<\/p>\n

In episode 1, which aired on the 10th, Yoon captured the everyday frustrations of office life as she nervously navigated Seong Hee-ju\u2019s pressure following poor product sales, even trembling while taking orders.<\/p>\n

In episode 2, broadcast on the 11th, Yoon carried out a covert assignment to gather information on Prince Ian (Byun Woo-seok) and, delighted, asked, “Did I get on the CEO\u2019s good side?” \u2014 a beat that injected fresh energy into the story.<\/p>\n

Set in an alternate South Korea operating under a constitutional monarchy, “21st Century Grand Lady” follows the romance between commoner-turned-tycoon Seong Hee-ju and Prince Ian. The series airs Fridays and Saturdays at 9:50 p.m. thunder@sportsseoul.com<\/p>\n","protected":false},"excerpt":{"rendered":"
