On October 29, Billlie’s Tsuki appeared as a guest on Radio Star, a MBC variety show, along with Jung Kwan-yong, Park So-hyun, and Lee Jae-yul.

On the show, Tsuki shared that she loves working out.  “I love exercising so much, I reached a 3-lift total of 165kg. Through consistent training, I became stronger.”

However, her agency intervened after a photoshoot. Tsuki explained that the lighting and shadows made her legs appear bulkier, which didn’t align with the industry’s expectations of having a “slimmer” figure.

“As an idol, having slim legs is considered pretty, but I had a photoshoot, and when I looked at the pictures, my legs looked like a horse’s due to the shadows. So, I was told I couldn’t do muscle training for a while.”

Her candid statement highlighted how even healthy habits like exercise can be restricted in the K-pop industry due to unrealistic beauty standards.

Despite the restriction, Tsuki shared that she has since found a new way to stay active: “Now running is my hobby.”

Following the episode, the revelation sparked a wave of online backlash. Fans expressed concern about how little autonomy idols have over their own health and bodies.

  • 3 reps of 165 cm LOL
  • Sigh, if those legs count as long, then 99% of Koreans must be living the life of elephants.
  • She looks healthy and full of vitality. I like her personality too.
  • She said, ‘Running is trendy these days, so I’ve taken it up as a hobby.’ — That’s honest. Doing it because it’s trendy. You just can’t hate someone like that.

Others also noted that Tsuki’s experience wasn’t unique, recalling similar stories shared by other female idols who were told to avoid certain exercises to maintain a specific body type.

While the situation drew criticism, many praised Tsuki for her honesty and courage in addressing a sensitive topic on national television — one that reflects broader discussions about body image and freedom within the K-pop industry.
