Hui On 'Favorite Entertainment'

In other related news, Hui has been busy performing as a trot group for the show 'Favorite Entertainment.' The trot group consists of Hui of Pentagon, MJ of Astro, and Ock Jin Wook and has been promoting the group together.

On the August 1 broadcast of 'Favorite Entertainment,' the show followed the group as they prepared for their first live performance. The group was seen practicing together, with MJ missing his cue because he was busy shouting along to the song, but their coach applauded him, saying, "you precisely understand the feeling (of trot)."

After practicing for a week, Hui and the rest of the group performed live in front of thirty Koreans and thirty foreigners mixed in. The group performed 'Gimme Gimme' by Kim Shin Young's alter ego Second Aunt Davi, 'Rokkugo!' by Super Junior-T, and 'Come' by Jang Yoon Jung.

After the performance, Hui commented, "Since it was our first performance, we were nervous, and it wasn't perfect. But, I'm thankful that we were able to show what we prepared."
