MBLAQ attended the showcase commemorating the release of their sixth mini-album 'Broken' at the Children's Grand Park in Seoul on March 24.  Here, Lee Joon revealed something surprising to his fans.

Lee Joon said, "My mother told us that she wanted to give us a song, but as she only wrote school songs before, I turned her down.  She put in sound effects and these days, she even practices these things all night," surprising the other members.

He said, "The song is good, but I thought the quality might fall.  However, my mother is even now diligently writing songs for us."

Seungho said thoughtfully, "I didn't know she was working hard for us without us even knowing.  I want to at least sing a duet with her."
