It's BTOB 5 year Anniversary! BTOB Community has been preparing and celebrating for this moment. We are going to share the evolution of BTOB from 2012 to present. I had found some videos that show how much they had changed. Even though their appearances had changed, they are still goofy as when they debuted 5 years ago.

What do you think? Can you see a difference from when they debuted and how they are now? I mean music style wise?
