After School's Kahi cheered on her new label mates NU'EST.

On March 16th, Kahi wrote via her official Twitter page, "NU'EST finished their first debut stage! 'Fighting' to an awesome beginning!"

She continued, "2AM who made a comeback and they were awesome along with 2nd place finisher Ailee who put on a killer live performance and was awesome too! So good to see everyone enjoying themselves on stage! No words needed for Big Bang who won a #1 win without even performing!"

Ahead of her tweet, NU'EST performed their debut song "Face" on KBS 2TV's 'Music Bank'. They perfectly pulled off their 'chair' choreography to their upbeat, exciting rhythm.

Kahi's Twitter followers who read her tweet remarked, "So good to see her take care of her juniors~", "Congratulations to NU'EST on their debut~", "Big Bang Zzang!", and more.

In related news, Big Bang won their second consecutive #1 K-Chart win this week on Music Bank.
