Subin of Dal Shabet recently uploaded a video to Instagram of her speaking Kazakh (correct me if I’m wrong) to fans in Kazakhstan, where they recently performed.

Never heard of a K-pop group going to Kazakhstan before, but Dal Shabet, VIXX, Kim Tae Woo, Seo Kang Joon, Hanbyul, 2MAX, and December were also at the event, called 2016 Feel Korea.
Anyway, thought it was quite a cool gesture of her to record this for her fans in the country since we always hear K-pop idols speaking Korean (obviously) and English, or even Japanese and Chinese, but rarely (never?) Kazakh.
