TEEN TOP's Niel, who recently made his return as a solo artist, and Pentagon's Hui made a lively appearance as guests on KBS CoolFM's 'Lee Eun Ji's Gayo Plaza', which aired on January 17 KST.

During the show, Hui shared a heartwarming anecdote, revealing that all the members of Pentagon showed up at the music video filming site for his solo album's title track, "Hmm BOP".

Gratefully, Hui mentioned, "What's even more surprising is that they didn't tell me they were coming; they just showed up." To add some humor to the situation, radio host Lee Eun Ji playfully remarked, "Isn't that for content?" Hui then explained, "I usually announce, 'I'm going,' but this time, there was no notice. When I finished filming the music video and came out, they were all waiting for me."

Meanwhile, Niel light-heartedly expressed his mock disappointment by saying, "The TEEN TOP members didn't even make an appearance. Those rascals," while adding a touch of humor with, "I haven't followed them on social media yet, and I won't in the future either."
