On October 6 episode of tvN's talk show 'Amazing Saturday', JB made a guest appearance.
Not long after the talk began, one of the cast BOOM asked another cast Hyeri, "Do you know JB?"
As she hesitantly said, "Yes." followed by an awkward smile, other hosts started growing their suspicion.

With a grin, he continued, "They might have dated for a bit when they were trainees, or..."

All people at the studio reacted, "You guys must be close then."

He went on, "But Hyeri just spoke informally to me when we met for the very first time."
Hyeri talked in shock, "Did I? I wouldn't have done that."
JB answered, "You did. So, I was like, 'Alright, whatever.' and that's how we got close."
