Early life and background

Kim Woo-jin was born on 8 April 1997 in Bucheon, Gyeonggi Province, South Korea. He grew up in Bucheon and later attended the School of Performing Arts Seoul, from which he graduated. Music was a lifelong ambition: he has said that becoming a singer was his childhood dream. He trained for a year at SM Entertainment before moving to JYP Entertainment in October 2017 to continue his preparation as an idol trainee.

Career

Woo-jin first appeared to the public as a contestant on Mnet’s reality survival series that formed the boy band Stray Kids. The show concluded with the creation of Stray Kids and the group released a pre-debut mini-album titled Mixtape in January 2018. He debuted with the band on the album I Am Not (2018).

In October 2019 JYP Entertainment announced that Woo-jin had decided to leave Stray Kids following the end of his exclusive contract, citing personal reasons. After his departure he pursued a solo career as a singer and actor.

As a solo artist he released his first solo album, The Moment: A Minor, in 2021. He continued releasing music and in 2023 put out his second EP, The Moment: Bounce. His solo work has been acknowledged at award events; in 2023 he received a Best Artist award at the Asia Top Awards.

Woo-jin has contributed original soundtrack songs for South Korean television series, including "Because It’s You" for Let Me Be Your Knight (2021), "In the End" for Reborn Rich (2022), and "Dive" for King the Land (2023). He also appeared as himself in the 2021 documentary film Finger Killer.

In addition to recording, Woo-jin has performed on stage and screen. In 2022 he embarked on his first world tour, titled Still Dream. He made his acting debut in an HBO Max series in 2023, playing the role of Kyung-min in Beyond the Closet. That same year he took on musical theatre, appearing as Adam Anderson/Eric Anderson in Sherlock Holmes: The Secret of the Andersons.

Public profile

Physically, Woo-jin is listed at approximately 175 cm (5'9") and around 65 kg (143 lbs). He has black hair and black eyes. Fans know his official fandom name as CUBS. Outside of work he enjoys listening to music, playing games and shopping. He has said that if he had not pursued singing he might have become a music teacher or vocal trainer.

Musically versatile, Woo-jin plays guitar and has trained in kendo, a modern Japanese martial art. His musical tastes include artists such as Bruno Mars and Gaho, and his favourite foods include tandoori chicken and chicken with cheese. He identifies as non-vegetarian and favors the autumn season.

Controversy and legal response

In September 2020 Twitter posts alleged instances of sexual harassment involving Woo-jin. He denied the claims, stating he did not know the accusers or the locations mentioned, and pursued legal action for defamation. Subsequent examinations and reporting noted issues with the evidence cited in the social-media allegations; a 2021 documentary titled Finger Killer examined those allegations and their aftermath.

Latest updates

Recent highlights include his 2022 world tour Still Dream, the 2023 EP The Moment: Bounce, his role in Beyond the Closet (2023), and his appearance in the 2023 musical Sherlock Holmes: The Secret of the Andersons. He continues to release soundtrack work for television and to perform both as a solo artist and on stage.
