Choo Sung Hoon is set to reveal behind-the-scenes stories about his YouTube Gold Button and his family life on the upcoming episode of MBC’s 'Radio Star'.

Choo recently surpassed one million subscribers on his YouTube channel, earning the coveted Gold Button from the platform. On Radio Star, he shares how his daughter, Choo Sarang, reacted to the milestone — a response that reportedly left even him surprised.

The episode also touches on the unexpected fallout from a video in which Choo revealed his luxurious 5 billion KRW (3.6 million USD) home in the heart of Tokyo. 

While the video garnered plenty of attention, it also led to his wife, model Yano Shiho, telling him to “shut down the channel,” sparking laughter among the cast as they playfully scolded him on her behalf.

Choo also revisits his legendary “dragon burp” moment from a previous Radio Star appearance, promising to top it this time. He takes on the challenge again with a full gulp of soda and even tries a one-handed push-up challenge, showing off his impressive physical strength.

He also dives into his athletic family roots, revealing that his father was a judo practitioner, his grandfather a boxer, and his mother — now in her 70s — still swims daily with a routine that professional athletes would struggle to match. A clip of his daughter Sarang showing off her skills in swimming and boxing further highlights the family's athletic DNA.

In a touching moment, Choo presents an old digital camera once owned by his late father, filled with family photos that moved the cast.

From heartfelt stories to laugh-out-loud moments, Choo Sung Hoon’s appearance on Radio Star promises both warmth and entertainment.
