~ Oh Geun-sae screaming his sentiments to Mr. Park.

Oh Geun-sae is the main antagonist of the 2019 Oscar-winning South Korean film Parasite. He is the husband of Guk Moon-kwang, who hid in a bunker for four years before the events of the film to escape loan sharks. 

He was portrayed by Park Myung-hoon


Moon-kwang rings the bell and asks to be let in, claiming that she comes to retrieve something in the basement. As the rest of the family hides, Choong-sook lets Moon-kwang in. In the basement, the former housekeeper opens a secret door to a bunker, where her husband Geun-sae has been hiding for 4 years to avoid the loan sharks.

As Choong-sook threatens to call the police, the rest of the Kims stumbled into view. Moon-kwang quickly captures the Parks' new driver and tutors addressing each other as father and children. As she threatens to send the clip to the Parks, a fight ensues and the Kims subdue the couple.

The phone rings and they learn that because of heavy rain, the Parks have cancelled the camping trip and will be home soon. The Kims scrambled to confine Moon-kwang and Geun-saw, then clean up and hide, while Choong-sook makes ram-don as requested by Mrs. Park. Moon-kwang breaks free and runs up the basement stair into the kitchen, but Choong-sook kicks her back down, severely wounding her. Later, Moon-kwang dies from her wounds as Geun-sae cries.

The following day, Mrs. Park throws a birthday party for her child, Da-song, and invites the Kims to participate. As the party proceeds, Ki-woo carries his lucky rock down to the bunker, intending to use it as a weapon to dispose of Geun-sae. Geun-sae ambushes Ki-woo and cracks his head open with the rock.

Geun-sae stabs Ki-jeong in the chest. His appearance triggers Da-song's traumatic memory and the kid begins to have a seizure. Ki-taek rushes to stop Ki-jeong's bleeding, but Mr. Park yells at him to throw the car key over so he can drive Da-song to the hospital. Realizing that Geun-sae was right about rich people, Ki-taek grabs the knife and stabs Mr. Park before running away. The thrown key is trapped under the fighting Choong-sook and Geun-sae. Choong-sook kills Geun-sae with a meat skewer.

In the aftermath of Geun-sae's murderous rampage, it's revealed that Ki-woo survived his injuries but Ki-jeong did not make it and died from her wound while Ki-taek has retreated into the same bunker where Geun-sae lived for four years. This leaves the police with no clue of where Ki-taek is, yet Geun-sae's motives are left a mystery to the public. Convicted by the Parks for fraud, Ki-woo and Choong-sook go back to live in poverty, with the former aspiring to one day buy the former Park household to free his father. In this way, Geun-sae succeeded in avenging his wife's death, as his actions destroyed both the Kim and Park families.


  • Despite his antagonistic role, Geun-sae isn't considered a villain by director Bong Joon-ho according to an interview with Empire. In Joon-ho's words, there are no true antagonists in Parasite as every main character has sympathetic and unsympathetic qualities, especially the Kims and the Parks. For this wiki's sake and in general, however, Geun-sea is considered an antagonist, given his murderous rampage against the Kims at the climax to avenge Guk Moon-kwang's death.
  • It is possible that Geun-sae's murderous rampage during Da-song's birthday party may have killed the boy. As Geun-sae caused a trauma on Da-song, his appearance during the party triggered Da-song's fears and caused him a seizure, and Mrs. Park previously said that if one of Da-song's seizures are not treated in fifteen minutes it can place him on serious danger. This is unconfirmed, however, as Da-song never appears in the film after that.
  • Some people interpret that Geun-sae being the one to kill Ki-jeon symbolizes her punishment for not alleviating Da-Song's trauma through art therapy. While the other members of the Kim family helped by Parks by teaching Da-hye, driving Mr. Park to his work and performing housework, Ki-jeon is so far the only one who didn't help the Parks. Thus, the "ghost" kills her for not curing Da-song's need for medical attention.
