The K-entertainment world is buzzing today with some seriously heartwarming news. Our favorite “soulmate” duo, IU and Yoo In-na, are officially reuniting on screen, and they’re bringing a very special guest along for the ride.
According to recent reports, IU and her 21st Century Grand Military Lady co-star, Byeon Woo-seok, are set to appear on the highly anticipated new program, You In Radio. Hosted by the ever-charming Yoo In-na, the show is already becoming a must-visit spot for top stars looking for a cozy, deep-dive interview.
Fans of “U-In-Na” (the adorable nickname for the two besties) know this isn’t just any interview. These two have been inseparable since meeting on a variety show back in 2010. Despite an 11-year age gap, they are the gold standard for friendship in the industry. Seeing them trade stories in a relaxed, radio-style setting on You In Radio is basically a dream come true for longtime followers.

But there’s an extra layer of excitement here: Byeon Woo-seok. This marks a massive return for the actor, his first major project since the whirlwind success of Lovely Runner. Seeing how he fits into the legendary chemistry between IU and Yoo In-na is the “X-factor” everyone is waiting for.

The trio is currently coordinating schedules for the pre-filming stage. They aren’t just there for the laughs, though; they’ll be promoting their upcoming MBC drama, 21st Century Grand Military Lady, which hits screens on April 10. Imagine a modern-day South Korean monarchy where a commoner and a prince try to change their destiny—it’s the “status-busting” romance we didn’t know we needed.
Between appearances on Salon Drip and Pinggyego, the cast is going all out for this promotion. However, You In Radio feels different. It’s personal, it’s cozy, and with Yoo In-na’s classy hosting style, we’re likely to get the kind of deep, behind-the-scenes stories you won’t hear anywhere else.
