BtoB celebrated their 1 year anniversary!

A year ago on March 22, 2012, BtoB debuted with "Imagine" and "Insane" on 'M! Countdown'.

Time flies fast as it's already been a year since their debut, and Peniel took to BtoB's official Twitter to celebrate. He wrote, "Woo!! 1 year since our debut! Wow... Congrats us! :) haha :P shout outs to everyone that has supported us up until now! We promise to keep working hard so expect a lot alright? ;) Thank you guys so much!! :D".

It's been a while since BtoB last promoted with "WOW", so fans are patiently waiting for their return. The members have been active in various dramas, variety shows, vlogs, and by featuring in other artists' songs.

Congratulations to BtoB!
