Eunice
Biography
Who Is Eunice of DIA?
Eunice (유니스), born Heo Su-yeon on September 2, 1991, in Busan, South Korea, is a South Korean idol, singer, and dancer best known as the main vocalist and main dancer of the K-pop girl group DIA. As the oldest member of the lineup, she has been called the group’s steady anchor, and she is widely recognized among fans as the only original member to take part in every single DIA activity since the group’s debut.
Early Life and Trainee Years
Before she ever stepped on a DIA stage, Eunice walked a long and winding road familiar to many K-pop idols. She first trained under Star Empire Entertainment and, for a brief stretch, became attached to the girl group Jewelry under her real name. That lineup never released material with her, so she moved on to MBK Entertainment to keep chasing her debut. Years of dance training at what would become Korea National University of Arts sharpened the choreography skills fans see in every DIA comeback today.
Debut With DIA and Rise as a Performer
Eunice finally debuted on September 14, 2015, as part of DIA’s first studio album, “Do It Amazing.” From that day forward, she built a reputation as a dependable main vocalist and main dancer, later stepping into the leader role during the “Happy Ending” era. In December 2016 she joined DIA’s first official sub-unit, BCHCS, expanding her reach beyond the full group’s promotions. Her bass-playing skills and songwriting credits, including co-writing “Will You Go Out With Me,” show a musician who does far more than just perform in front of the camera.
Milestones, Music Show Win, and Group Hiatus
DIA celebrated its first-ever music show win with “WooWoo” on The Show in 2018, a milestone Eunice experienced firsthand as one of the group’s longest-standing members. When DIA parted ways with PocketDol Studio in 2022 and shifted toward individual schedules, Eunice used the moment to explore a solo path, releasing her debut solo single “Blue Ros3 (miracle)” in May 2023.
Personality and Fun Facts
Off stage, Eunice is known for a laid-back, playful streak: she is a devoted Homer Simpson fan (hence the nickname “The Simpson Nerd”), enjoys collecting action figures, and keeps a lighthearted “Tom and Jerry” rivalry with fellow member Huihyeon. Longtime AID fans appreciate her warmth, consistency, and the quiet dedication that has carried DIA through nearly a decade of changes.
