Fact Check: Hyein's Real Age in 2023 and the Truth Behind Her Rapid Debut
By David Miller
Public astonishment over Hyein’s early competence overlooked a critical detail: she entered the industry long before ADOR signed her. She had built an extensive professional portfolio throughout elementary school.
At age eight, Hyein began working as a commercial child model. Her portfolio expanded rapidly across youth fashion catalogs, runway shows, and magazine editorials. By 2017, she joined the kids' pop group USSO Girl under the stage name U.jeong, releasing singles and performing on small stages across Seoul. That project served as an early testing ground for synchronized group routines and live microphone work.
She later became a prominent cast member on Pocket TV's popular YouTube variety program Play With Me Club. From 2019 to 2021, she appeared in dozens of videos, documenting dance practice sessions, vlogs, and beauty tests. Audiences watched her develop self-presentation skills on camera in real time. Her public history was not hidden; archives of her practicing BTS and TXT choreographies circulated widely after ADOR announced NewJeans.
When ADOR CEO Min Hee-jin held global auditions to construct NewJeans, Hyein brought camera readiness that few peers possessed. She did not require remedial media training. She had already accumulated thousands of hours in front of professional studio lights before ever signing her trainee contract with HYBE.
