Cube's new boy group Pentagon had their debut showcase on October 10 where they talked about their agency seniors.

As this was Cube's first boy group in four years after BTOB, Pentagon was asked about any stories involving their seniors.  Member Hongseok said, "HyunA and CLC came to the MV set to show their support.  They recharged our fighting morale so we went on (full of energy) growling."

Shinwon added, "BTOB's Eunkwang gave us good advice.  We will work even harder in order to not damage the names of B2ST and BTOB."

They were then asked what sets them apart from those two boy groups, and leader Hui said, "Rather than differences, we want to become a group that can combine the voice of BTOB with the elegant performance of B2ST." 

Good luck, boys!
