Background
Heekie's path to debut was defined by patience and perseverance. Before joining High Up Entertainment, she spent years training under some of South Korea's biggest entertainment companies, including YG Entertainment and Source Music. Those experiences exposed her to different training styles and helped shape her into a well-rounded performer long before UNCHILD was formed. Altogether, she trained for roughly eight to nine years, making her the group's longest-trained member and one of the most experienced rookies of her generation.
In April 2023, Heekie joined High Up Entertainment, where she continued preparing for debut while helping build the chemistry of the future UNCHILD lineup. Her leadership qualities and years of experience eventually earned her the role of group leader. Officially introduced as a member on April 7, 2026, Heekie debuted with UNCHILD just weeks later, playing an active role not only as a performer but also as a choreographer for the group's debut.
