On June 22 episode of SBS' television show 'Sleep Out', the members were seen sitting around a campfire outside in the evening.
Each member of 'Sleep Out' read out a letter that they wrote to each other, and Moon Byul was the first one to read hers out.

With teary eyes, she continued, "So, I've been thinking to myself, 'Is it right for me to keep working in this industry? Is this the right job for me?' But I'm worried that if I take a break now, then I'll have to start all over again and build this whole career again.'"
She went on, "I feel like there won't be any next if I take time off now. So, there are lots of things going inside my head these days. But I feel like I get to forget all my worries when I'm with you guys. Meeting you guys was one of the best things that has ever happened to me. I would like to thank you for that."
Lastly, she added, "Thank you for giving me your warm support at all times. My heart felt warm. I want to become an unnie like you guys when I get older."

Ba-da also stated, "I know exactly how you feel, Moon Byul. I've been there myself in the past. 10 to 20 years ago, we've felt exactly the same as how you feel now. That's why we were able to give you advice, and try to look after you more. It's okay."
