EJAE's journey from a long-term K-pop trainee to the singing voice behind Rumi in Kpop Demon Hunters has been described by fans as one of endurance, quiet perseverance, and eventual recognition. For years, online speculation claimed she was rejected from idol line-ups for being 'too old'. But the truth tells is far more layered: one grounded in timing, company direction, and the realities of the idol system, not her age.
According to Chosun Ilbo, one of South Korea's leading newspapers, EJAE trained under SM Entertainment for over ten years beginning in 2003. Born in December 1991 in South Korea and raised in the United States, she returned to Seoul to chase her dream of becoming a K-pop idol. While attending an international school, she balanced education with relentless training, waiting for her long-promised debut.
