'Knowing Brothers' revealed next week's preview featuring BTOB.

In the preview for the February 26th episode of JTBC's 'Knowing Brothers', Minhyuk, Changsub, Hyunsik, Peniel, and Sungjae gather together for the first time as a group in 4 years after serving their mandatory military service. Eunkwang was absent as he tested positive for COVID-19. 

On the upcoming episode, Sungjae and Minhyuk reveal the talents that would likely never make them any money, the BTOB members play the show's headphone game, and the 'Knowing Brothers' cast members compete against the idol group with water guns and flour balloons as punishments.

In other news, BTOB are making a comeback with their full album 'Be Together' on February 21 KST.
