Hyein is the youngest member of NewJeans, the ADOR girl group under HYBE that debuted in July 2022. The group broke from K-pop habit by releasing music and videos with no advance teasing, and it quickly became one of the most discussed girl groups of its era. After a long contract dispute with the label, Hyein returned to ADOR along with Hanni and Haerin, and Minji's return followed in the summer of 2026. In July 2026 the four-member group marked its fourth anniversary with a film series that featured Hyein in her own short film.
