BTOB's "boring-line", supposedly consisting of Hyunsik, Ilhoon, and Peniel, made a guest appearance on the July 26 broadcast of 'Hongki's Kiss the Radio'.

The three "boring" BTOB members each introduced their solo singles through the 'Piece of BTOB' project. Then, they had a time answering questions sent in by listeners, including one which asked, "[I'm] curious what male fans mean to BTOB." Hyunsik answered, "First and foremost, we are thankful [for them]. When we see male fans at performances and such, it makes us really happy. They know this. That we actually like our male fans more." 

When tasked with telling any member, company staff, or managers something outright, Ilhoon said, "[The staff] tend to send music files in .wav format. The difference in file size is about 4 times that of .mp3 files, so I would appreciate it if they sent .mp3 files from now on." 

Finally, Hyunsik mentioned about the possibility of a BTOB comeback, "BTOB are preparing for an album, but there are no spoilers to give out just yet. BTOB's album will be out after everyone's solos. We will not comeback in the middle of the solos."
