Kim Jun Seo

Kim Jun Seo is a South Korean singer, born 20 November 2001. He finished ninth on the 2019 audition show Under Nineteen and debuted in the project group 1THE9, joined WEi when 1THE9 disbanded in 2020, is also a member of ALPHA DRIVE ONE, and is signed to OUI Entertainment. That system runs on an enormous funnel: thousands of trainees, years of preparation, and only a fraction who ever release anything under their own name. Surviving an audition show and then carrying on through more than one group already clears a bar that most people who attempt this never reach. He is in his mid-twenties now, at the point where a career either consolidates or quietly turns into something else.
