Girl group T-ARA's Hyomin showed off her cheerfulness at the filming set of KBS 'Invincible Youth 2.’

On May 31, Hyomin posted on her twitter, "I just came back from filming 'Invincible Youth.’ I laughed so much for the first time in a while I really enjoyed it. We filmed without having to worry about producing enough minutes. Really!", and also posted "Ace", along with three pictures.

In the pictures, Hyomin is posing with Girls' Generation’s Sunny, SECRET's Sunhwa, and Kim Shin Young. In other pictures, Hyomin and Sulli are showing off their beauty despite the country-like outfits they're wearing.

Internet users who saw this commented, "They're beautiful even though they're not dolled up", "Sulli and Hyomin together create light", and "Hyomin, I know it's late but happy birthday. Have a good day.”
