JBJ (Hangul: 제이비제이), also known as Just Be Joyful, was a South Korean project boy group under Fave Entertainment, consisting of six members who previously participated in the 2017 reality show Produce 101 Season 2. The members of the group were Taehyun, Kenta, Sanggyun, Longguo, Hyunbin and Donghan. CJ E&M Entertainment supervised the group's release production. Their contracts lasted about seven months after their October debut and they were, therefore, not permanent. On October 17, 2017, JBJ released their first extended play Fantasy. The title track "Fantasy" peaked at 23 on the Gaon Music Chart. On January 17, 2018, they released their first comeback with their second extended play True Colors and its title track, "My Flower". Later that year, on April 17, the group released a special deluxe edition of the previous two EPs, titled New Moon. The album has three new tracks, one of them being the title track "Call Your Name", and it was their final album. They officially disbanded at the end of April 2018. Currently, member Taehyun is a member of his pre-JBJ group, HOTSHOT, and is also a soloist singer under his full name, Roh Tae Hyun. Sanggyun, who left his company and consequently his pre-JBJ group Topp Dogg, is now signed to Kenta's company and together they form the duo JBJ95. Longguo and Donghan (under his full name Kim Dong Han) are soloists singers and Hyunbin continued with his acting career.
