A Pink's Hayoung put Super Junior's Heechul on blast on 'Knowing Brothers'.

 
On the June 30th installment of the show, Hayoung spoke up, saying, "I have something to say to Heechul," making everyone pay attention. He responded fearfully, "I took care of you on 'Game Show', didn't I?"

However, the A Pink member continued, "I was unimportant to him. Heechul's ideal type is a woman he's seen for the first time. When he first meets you, he treats you really well, but when female guests come on, he would turn his back to me. I felt disappointed."

Heechul explained, "We were close, so there was no reason for us to act. We were family," but Hayoung joked, "How am I your family?"
