Park Seo-jun and Han So-hee return to lead the cast of Gyeongseong Creature Season 2 on Netflix.

Season 1 of the sci-fi Korean series revolves around a dangerous parasitic organism called "Najin" which causes its host to mutate and turn into a terrifying monster. 

Gyeongseong Creature's debut season is set in 1945, focusing on Chae-ok's search for her missing mother whom she later discovers as the Najin's main host. 

Season 2 puts the spotlight on modern-day Seoul in 2024, but it still focuses on Chae-ok as the main protagonist. Gyeongseong Creature Season 2 premiered on Netflix on September 27.

It is later revealed that Ho-jae and Yong-gil are actually private investigators who work on low-profile cases.
