On the recent episode of MBC's television show 'Buddy into the Wild', Byul made a guest appearance.
While watching a video of HAHA and singer Sung Si-kyung on a trip together, Byul commented, "I'm actually a huge fan of Sung Si-kyung."
She continued, "Sung Si-kyung is a singer that all other singers look up to, you know. He will always be my very celebrity."

Byul said, "There was this time when I talked about Sung Si-kyung to HAHA. At that time, I referred to Sung Si-kyung as Si-kyung oppa."
She resumed, "HAHA was like, 'Don't call him Si-kyung 'oppa'.'", then laughed at HAHA's cute jealousy.

He went on, "Not only is he tall, he also went to one of the three top universities in Korea. He's also got a candy-like voice."
Another host Yoo Se-yoon jokingly responded, "Yeah, I hate that guy so much."
