Jang Gyu-ri, the South Korean actress and former fromis_9 member who plays Hong Jae-in in Four Hands, Two Sonatas

Jang Gyu-ri

BIOGRAPHY

Jang Gyu-ri (Korean: 장규리; born 27 December 1997 in Seoul) is a South Korean singer and actor signed to JUST Entertainment, with twenty-one screen credits.

She is a former member of the girl group fromis_9, and moved into acting after the group.

In tvN’s 2026 music drama Four Hands, Two Sonatas (포핸즈) she plays Hong Jae-in, a viola major with a sharp musical ear who is looking for music that actually resonates with her, across all twelve episodes.

BLGLFlix editorial view

Twenty-one screen credits is a working actor rather than a crossover experiment, and that is worth setting against the story usually told about idols who move into drama. Jang Gyu-ri left fromis_9 and kept working. The acting is the career now, not a side project attached to a music one.

Only one of those twenty-one credits brings her onto this site. Four Hands, Two Sonatas is recorded here as a bromance rather than a Boys’ Love series, because no source describes it as one. The distinction matters: a close male friendship written with real weight is not the same thing as a romance, and treating the two as interchangeable would misrepresent both the show and the genre.

One small conflict is left visible rather than smoothed away. TMDB gives her character only as Jae-in, while the English Wikipedia article on the series gives the full name Hong Jae-in. The fuller version is used on this page, and the shorter one is what appears on TMDB.
