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."
