Shocking top-of-class credentials and a striking glow-up—actress Goo Hye Sun returns to MBC's variety show Radio Star with her first update of the new year, promising candid talk on how "speaking it out loud" turned her goals into reality.
The January 21 broadcast of Radio Star features Lee Geum-hee, Yeom Kyung-hwan, Goo Hye Sun, and Jeon Min-ki in a special titled "2026 Words, Words, Words: Say It Out Loud!" On the show, Goo Hye Sun shares how she first declares her goals, then holds herself to those promises—and sees them through.
Walking the path of a late-blooming scholar, she looks back on the time she balanced studies and daily life—graduating at the top of her class from Sungkyunkwan University and even finishing her KAIST graduate program early. It's a window into her philosophy that "once you say it out loud, you're less likely to give up."
Her transformed visuals are also going viral. After consistent self-care, Goo Hye Sun says she dropped her weight into the "40s" kilogram range, arriving with a fresh hairstyle and self-picked floral accessories that completely changed her vibe and lit up the studio. Cast members couldn't help but recall her Geum Jan-di era from the drama Boys Over Flowers, reacting with visible surprise.
Her multi-hyphenate career takes the spotlight too. Beyond acting, Goo Hye Sun has challenged herself as a film director, painter, composer, and even an inventor—sharing behind-the-scenes episodes from her work as a composer. In particular, she reveals how singer Lee Juck personally visited to offer advice, then shows her musician side by singing on the spot.
She also revisits headline-making moments from her past. Calmly reflecting on misunderstandings and public scrutiny, she doubles down on her conviction: "If you don't say it, it's easy to give up." With her candid remarks and humor, she even shares an anecdote about disarming antis—sending the studio into laughter.
Goo Hye Sun's honest story about building a life exactly as she declared it can be seen on Radio Star on the 21st at 10:30 p.m.
