2009–2014: Debut and career beginningsEdit

JB is a former B-boy. He, along with member Jinyoung, successfully auditioned for JYP Entertainment in 2009, both winning first place at the open audition.[7]

In 2011, JB was cast in the role of Jang Woo-jae in the television drama Dream High 2.[5] The drama began airing on January 30, 2012 on KBS for 16 episodes.[8]

In May 2012, JB and fellow trainee Jin-young debuted as the duo JJ Project with the single album Bounce.[7][9] Their official music video for the title track "Bounce" was released on May 19.[10]

On March 11, 2013, it was announced that JB would be appearing as Seo Mi-joon on MBC's new drama When a Man Falls in Love.[6] On January 16, 2014, the two members of JJ Project debuted as part of a seven-member boy band called Got7.[11]


In 2015 JB played the lead role in Dream Knight, a virtual musical television drama, as a superhero version of himself, alongside his fellow Got7 members, featuring actress Song Ha-yoon as the female lead role.[12][13] He was nominated for the "Rising Star Award" at the K-Web Fest in July.[14]

On November 24, 2017, it was revealed that JB had donated 10 million won to the Pohang Earthquake Relief Fund.[15]

In 2018, together with group mate Yugyeom, he participated in the art collaboration project "Collaboran" for carbonated mineral water brand Perrier with American multimedia artist Ben Jones. The creation process was revealed through a reality show released in May.[16]

On March 5, 2019, JB and his group mate Yugyeom debuted as a duo, Jus2, which is a sub-unit of Got7.

Personal lifeEdit

During his younger years, his parents divorced due to his father's drinking problem, and his mother later remarried.[17] His family runs a tomato farm in Ilsan.[18]

On September 12, 2014, JB was involved in a minor car accident while the driver was trying to change lanes to avoid a parked car when a bus came up behind, causing their car to hit a van. Neither JB nor his staff suffered major damage.[19]

In 2016, JB was unable to participate in several Got7's Fly Tour concerts and a M!Countdown performance due to a spinal disc injury.[20][21] He returned for the Fly in Singapore concert at the Suntec Singapore Convention & Exhibition Centre, showing a full recovery.[22]

JB is currently majoring in Film at Konkuk University.[23][24]
