JBJ is a project group made of Noh Tae Hyun, Takada Kenta, Kim Sang Kyun, Kim Yong Guk, Kwon Hyun Bin, and Kim Dong Han. All of the members are from 'Produce 101', and it's a group that came together because fans so badly wanted to see their formation. Originally, their contract was to last until April, 2018, but CJ E&M, the boys' individual labels, and the boys themselves, are currently looking at extending the contract to December, 2018.
According to OSEN, all parties are currently talking optimistically on extending the contract. This means that JBJ will end at the same time as Wanna One.
