Profile

EUNSEO is a WJSN vocalist who has also pursued acting under her birth name Son Ju-yeon. Her group work includes the original 2016 debut, later studio recordings and the WJSN THE BLACK unit.

In 2023, her agency introduced updated acting-profile photos as she expanded her television work. The WJSN THE BLACK single and acting roles are not her own solo music album, so the profile does not claim a separate solo recording career.

Eunseo has contributed vocals and performances to WJSN and the THE BLACK unit, while also working in acting. The unit’s music belongs to a collaborative lineup rather than to her individual solo discography.
