SEOUL, June 23 (Yonhap) -- Kim Mu-yeol and Jung Ryeo-won have been cast in Netflix's new medical drama series "First Doctor," directed by Hong Jong-chan of hit series "Teach You a Lesson" (2026) and "Juvenile Justice" (2022), the streaming giant said Tuesday.

Jung will lead the series as Heo Ji-wan, a pediatric surgeon dubbed the "troublemaker" at her hospital for her blunt and reckless personality, but who is devoted to protecting her child patients and saving the pediatric surgery department from closure, according to Netflix.

Kim, who led the cast in the recent hit "Teach You a Lesson," will play Bae Su-wol, an easygoing anesthesiology professor, who is a longtime friend of Heo.

The cast also includes Ha Yoon-kyung as Ki Eun-gyeol, a clever third-year resident who often clashes with Heo. Ha previously appeared in the television series "Extraordinary Attorney Woo" (2022) and "Hospital Playlist" (2020).

The upcoming series marks the second collaboration between Hong and acclaimed screenwriter Kim Min-suk, following "Juvenile Justice."
