On the August 12 broadcast of SBS PowerFM's 'Cultwo Show', GOT7's BamBam and Sunmi appeared as guests. Comedian Shin Bong Sun also joined as a special radio DJ.

On this day, BamBam revealed, "I'm still too shy to look at Sunmi directly in her eyes." He continued, "She feels like a celebrity, in my heart. When Sunmi debuted, I was probably 9-10 years old. She is a sunbae and also a star. Currently, it has become a lot more comfortable. But I still can't look at her eyes."
