On the June 7th episode of 'Kim Shin Young's Noon Song of Hope', DK Kim Shin Young asked Seolhyun about her friendship with Jung Hae In, and the AOA member responded, "We knew each other because we used to practice together a long time ago. Jung Hae In oppa's debut was in AOA's 'Moya' music video. That's why we know each other."
She continued, "Recently, I said we were friendly, but Jung Hae In oppa's gotten too popular lately." Jimin also added, "I'm kind of awkward with him."
DJ Kim Shin Young also mentioned, "Song Eun Yi said there's no kid as nice as Jung Hae In," and Jimin agreed, "That's true. He's very nice."
