Kim Hyun Jin is a South Korean singer, dancer, former member of LOONA (이달의 소녀), LOOSSEMBLE (루셈블), and LATENCY (레이턴시). She graduated from Hanseong Girls’ High School.

In October 2016, Blockberry Creative (블록베리크리에이티브) decided to debut a girl group through an 18-month-long pre-debut project. She was the second to be revealed and released her single "Around You" in November 2016. After 4 members were revealed, she formed the sub-unit LOONA 1/3 with them and released the EP "Love & Live" in March 2017.

She officially debuted in August 2018 as the group's dancer, vocalist, rapper, and visual with their first EP, "[+ +]".

In November 2022, member Chuu was removed from the group after winning a partial injunction against the agency to terminate her contract. The company blamed Chuu and cited an abuse of power as the cause for her removal. However, the remaining members filed an injunction to terminate their contracts three days after Chuu was removed. The agency even teased a comeback scheduled for January 2023, which was promptly boycotted by the fans and postponed indefinitely. In May 2023, her injunction was granted, and she left the company.

She signed with CTDENM (씨티디이엔엠) and re-debuted in September 2023 as LOOSEMBLE's leader, vocalist, dancer and visual with their first EP, also titled "Loossemble". The group was not successful and, on November 29, 2024, CTDENM announced that their exclusive contracts had ended, effectively disbanding the group.

In January 2026, she re-debuted once again, but now as the drummer of LATENCY, an all-female rock band managed by Oddinary Records (오디너리 레코즈), with their first single, "It Was Love". However, only months after re-debuting, she announced her departure from the band and the agency, citing health issues, as she was not fully prepared for the demanding requirements of being a drummer.
