JeA appeared on SBS powerFM's 'Choi Hwa Jung's Power Time' on April 5, where she talked about Jang Geun Suk, or Chief Jang, who mentored on Mnet's 'Produce 101' with her.

"How's Jang Geun Suk in real life?" she was asked.  She replied, "Among us, he was the youngest (maknae), but he bought us food quite a lot.  He put so much importance on catering, making us full.  I liked it."

Choi Hwa Jung said, "If he buys you a lot of food, he's your oppa and hyung."  JeA agreed with, "That's right.  However, we called him the Chief.  We'd say things like, 'Oh, did Chief Jang arrive?'"
