On April 1, 2026, viewers tuning into the popular MBC entertainment program Radio Star were treated to a special episode aptly titled "Loyalty Inducers." The show gathered some of the most beloved figures in K-pop and entertainment, including Jo Gap-kyung, Chae-yeon, Go Woo-ri, and Lee Chae-young of fromis_9. But it was singer Chae-yeon who captured hearts and headlines with her candid revelations about family, fame, and the unexpected twists of public life.
Chae-yeon, who has long held a special place in the affection of fans and even earned the affectionate moniker "military president" for her popularity among soldiers, took this opportunity to show a different side of herself—one deeply rooted in gratitude and filial piety. According to OSEN, she revealed on air that she purchased a building in Jayang-dong for her mother, fulfilling a long-held wish. "My mom always used to say, 'I wish I could own a building before I die,'" Chae-yeon shared, her voice tinged with both pride and humility. "It wasn't about investment. I grew up in the same neighborhood through elementary, middle, and high school, so I bought a building there."
The purchase, however, didn’t go unnoticed—or uncriticized. Chae-yeon admitted that some questioned her decision, with headlines even emerging about a supposed poor investment. "People asked, 'Why did you buy there?' and said it was foolish," she recounted. "But it wasn’t for investment. I bought it with care." As fate would have it, the value of the building has since doubled, prompting co-host Kim Gura to quip, "Your filial devotion ended up increasing the property value!"
Her acts of love didn’t stop with her mother. Chae-yeon also opened up about a touching moment with her father. She described a family outing to test-drive a foreign car—a moment that would become unexpectedly poignant. "We all went together, and after my dad took it for a spin, he said, 'I wonder if I’ll ever get to drive something like this before I die.' That really stayed with me," Chae-yeon recalled, according to Newsis. Rather than buying a car for herself, she chose a model that suited her father's tastes and gifted it to him. "It wasn’t something I did because I had to," she said. "It just felt right."
These gestures, funded by her earnings from years of broadcasting and performing, struck a chord with viewers and co-panelists alike. As Newsis reported, Chae-yeon’s willingness to share these personal stories underscored her reputation as a devoted daughter, a quality that resonates deeply in Korean culture.
But the episode wasn’t all about heartfelt family moments. Chae-yeon also addressed a lighter, albeit equally memorable, incident from her past: a notorious arithmetic blunder on a previous variety show. The slip, which involved a simple calculation gone awry, quickly went viral at the time. "It became a huge topic in a way I never expected," Chae-yeon said, laughing at the memory. The story took an even more surprising turn when she revealed that the incident was cited in an overseas academic paper—proof that even the most embarrassing moments can take on a life of their own.
"I never imagined my mistake would be referenced in an international study," she said, her amusement evident. The anecdote brought levity to the show and reminded fans that, despite her star status, Chae-yeon isn’t afraid to laugh at herself or share her vulnerabilities.
The night wasn’t all talk, either. Chae-yeon joined forces with Lee Chae-young of fromis_9 for a joint live performance, delivering a duet that showcased their vocal chemistry and stage presence. The performance, highlighted by Newsis, was a standout moment in the broadcast, underscoring the camaraderie and talent among the episode’s guests.
For those less familiar with Chae-yeon’s journey, her rise to fame has been marked by persistence and adaptability. Debuting in the early 2000s, she quickly became a household name, especially among younger audiences and in the military, where her energetic performances and approachable personality made her something of a legend. Over the years, she’s navigated the shifting tides of the entertainment industry, branching out into variety shows, acting, and even international performances.
Her appearance on Radio Star was a reminder of how celebrities, despite their public personas, often carry personal stories that rarely make the headlines. Chae-yeon’s willingness to discuss her family’s dreams and her own sense of responsibility offered viewers a rare glimpse into the motivations that drive her. It’s one thing to see a star on stage; it’s another to hear her reflect on the hopes of her parents and the joy of giving back.
It’s also worth noting the broader context of her gestures. In Korea, the concept of filial piety—showing respect and care for one’s parents—is deeply woven into the cultural fabric. Chae-yeon’s stories struck a chord not just because of their scale (a building and a foreign car are no small gifts), but because they embodied values that resonate across generations. As OSEN and Newsis both highlighted, her actions were less about material wealth and more about honoring the sacrifices and wishes of her family.
The episode’s "Loyalty Inducers" theme couldn’t have been more fitting. Each guest brought their own take on what it means to inspire loyalty, whether through music, personal stories, or unexpected acts of kindness. For Chae-yeon, loyalty meant looking back at where she came from and ensuring her parents’ dreams didn’t go unfulfilled.
Of course, the entertainment world is never short on surprises, and Chae-yeon’s story about her arithmetic mishap reminded everyone that even the most polished stars have their off days. The fact that her error was immortalized in an overseas academic paper adds a layer of irony—and perhaps a bit of comfort to anyone who’s ever made a public mistake.
In the end, the April 1 broadcast of Radio Star offered more than just laughs and performances. It provided a window into the personal values and heartfelt motivations of one of K-pop’s enduring figures. Chae-yeon’s blend of humility, humor, and generosity left a lasting impression—not just on her fellow guests, but on viewers across the country. Sometimes, the most compelling stories are the ones that remind us of the quiet power of family, gratitude, and the courage to share our true selves, flaws and all.
