On the June 2nd installment of 'Knowing Brothers', AOA's Seolhyun and Jimin as well as Kim Shin Young featured as guests. During her Q&A system, Seolhyun told the 'Knowing Brothers' cast, "I was watching TV with my parents, and my dad asked me, 'Are you really close with Heechul?'"
She continued, "I told my dad honestly, 'He only calls me during broadcasts, but we don't contact each other personally.' That's when my mom said, 'What a bad kid. I didn't think he would be like that.'"
