Heejin, born Jeon Hee-jin, is a South Korean singer best known as a founding member of the girl group LOONA, for which she was the first member revealed in 2016 ahead of the group's staggered pre-debut rollout. She released an early self-titled single, "Vivid," as part of that project. In 2022 and 2023, amid a contract dispute, Heejin and several LOONA groupmates terminated their contracts with their former agency and signed with Modhaus, the company led by LOONA's former creative producer Jaden Jeong. She became a member of ARTMS, the Modhaus girl group made up of former LOONA members, which debuted in 2024 with the album "DALL" and its single "Virtual Angel." Heejin also made her solo debut with the EP "K" in 2023. Known for her work across LOONA's conceptual catalog, she has continued her career under Modhaus in both group and solo settings.
