Yuna, the youngest member of ITZY who debuted in 2019, has been cast as the lead in the Netflix drama 'Don't Cross the Line.' The series depicts a high-teen romance between the student body presidents of rival boys' and girls' schools separated by a wall. Yuna began her acting career with a special appearance in tvN's 'Undercover Miss Hong' earlier this year, followed by a supporting role in the upcoming 'My Favorite Employee,' and is now taking on a Netflix lead role, accelerating her acting career. Ryujin, her groupmate, celebrates her 8th year since debut and has announced consecutive lead roles in films 'Shaving,' 'Night on the Ground,' and 'High School Detective' this year. Tzuyu from TWICE is also expected to begin acting activities, and Miyeon from (G)I-DLE has been selected as the protagonist of the new season of tvN's 'Bulgasal: Immortal Souls' following a special appearance in 'The Employee Who Sees Destiny.' Industry insiders analyze that acting activities among senior girl group members debuted 8-10 years ago have become noticeably active. Production companies increasingly prefer idols with existing fandoms and high public recognition over newcomer actors, as this secures buzz before release and ensures global interest.
