After more than a decade writing hits for K-pop acts behind the scenes, she’s now a front-facing artist, helped along by the announcement of a KPop Demon Hunters sequel.

K-pop, pop, R&B, dance-pop.

Vocals, piano.
Labels
Her KPop Demon Hunters recordings were released through Republic Records, which handled the soundtrack. Before that she worked largely as a credited songwriter through publishing deals rather than as a signed recording artist.

At an estimated 5 ft 4 in (163 cm), EJAE matches the average height of an American woman exactly and stands roughly eye-to-eye with K-pop vocalists like Red Velvet’s Wendy, one of the many artists she has written songs for.
Weight
Around 50 kg (110 lbs), estimated.
Boyfriend / Spouse
EJAE appears to be single as of 2026, and she’s never publicly confirmed a relationship. She’s one of the more private figures to come out of the K-pop writing world, and the handful of interviews she gave after KPop Demon Hunters exploded stuck almost entirely to music, her trainee years and the pressure of singing “Golden” live. No partner has appeared on her social media, and she hasn’t been linked to anyone in the Korean or American press. Given how recently she became a public name, that may change.

Best Known For
Singing Rumi’s vocals in KPop Demon Hunters (2025) as part of the fictional trio HUNTR/X, and co-writing “Golden,” which topped the Billboard Hot 100 and became one of the biggest songs of the year.
First Album
The KPop Demon Hunters soundtrack (2025) is her first major release as a performer. She sings lead on “Golden,” “How It’s Done” and “What It Sounds Like,” and co-wrote all three plus “Takedown.”
EJAE’s Favorite Things
She’s talked about loving big ballads and belt-heavy vocal arrangements, and she’s said Korean food is her comfort default. Her preferred working setup is a small home studio where she can cut demo vocals herself.
EJAE’s Facts
She trained at SM Entertainment for about a decade starting around age 11 and came close to debuting with the group that became Red Velvet. She never debuted as an idol.
Her songwriting credits include Red Velvet’s “Psycho,” plus cuts for aespa, TWICE and KATSEYE. Many listeners knew her name from liner notes years before they knew her face.
“Golden” was written as a demo she expected another singer to record. Her guide vocal ended up in the finished film.
The note on the word “soul” in “Golden” sits so high that it became a social media challenge in 2025, with thousands of failed attempts posted to TikTok.
KPop Demon Hunters became Netflix’s most-watched film ever, and the soundtrack put multiple HUNTR/X and Saja Boys songs into the Hot 100 simultaneously.
Rumi’s speaking voice is performed by actress Arden Cho, not EJAE. The two split the role.
Netflix confirmed a sequel with director Maggie Kang returning, which pushed EJAE back into the spotlight alongside her own solo material.
She records alongside Audrey Nuna and REI AMI, who voice Mira and Zoey respectively, as the singing lineup of HUNTR/X.
