K-pop boy band Wanna One caused controversy on Monday after Mnet broadcast their candid comments, which included swearing and complaining, hurting sales of their new album released the same day. 

The group's agency YMC Entertainment apologised for Wanna One’s scandalous remarks on Mnet's Star Live. The band released their second EP “0+1=1 (I Promise You)” the same day. 

“We will make sure similar incidents do not happen again,” YMC said.

Mnet released a behind-the-scenes video clip of the members bantering before performing.

In the footage, Park Ji-hoon was shouting about their lack of freedom.

“Why don't we get paid?” Kang Daniel said.

Park also complained about the members getting only 20 per cent of what they earn. Ong Seong-wu went on to complain about his lack of sleep.

Kang even mentioned, in vulgar terms, using the bathroom in the morning. 

The lead track from Wanna One's latest release, Boomerang, reached No 1 on Mnet Music, and No 2 on Melon, Soribada, Bugs Music and Naver Music at 8am on Tuesday. The boy band’s performance was weaker than I.P.U., released two weeks ago, which tops seven charts.
