Lee Chae-young

Lee Chae-young (이채영), known as Isa, is one of the members who gives STAYC its emotional texture. She debuted with the group on November 12, 2020 through Star to a Young Culture, joining the six-member roster that turned High Up Entertainment into one of K-pop's most efficient hitmaking labels.

Isa's profile lands best when it is framed through STAYC's full catalog arc rather than a generic member summary. The group built momentum by keeping its songs sharp, melodic, and instantly replayable, and that discipline carried through later releases including WE NEED LOVE, TEENFRESH, and Metamorphic. Isa sits inside that structure as part of the member mix that kept the group from feeling interchangeable.

By 2026, STAYC's importance inside High Up had only grown. The debut of UNCHILD made the label's expansion strategy visible, but STAYC remained the act that proved the producer vision could sustain a real long-tail idol brand. Isa's page matters because it connects that bigger label story back to one specific artist inside the lineup that made it work.
