Is Joo Kyul Kyung the pronounciation of Zhou Jieqiong? Or is Kyul Kyung her Korean name and Jieqiong her Chinese one?
EDIT: Also I just want to say, Nayoung is my girl crush. She's so pretty. I think her showing no emotions makes her very funny

Or maybe it's just the way they edited it, but it's funny

Stone Nayoung.
