Parasite Movie

Ki-woo is the son of the Kim family, a smart and ambitious young man who feels held back by poverty. After getting referred for a tutoring gig, he orchestrates a plan in which his whole family begins working for the same wealthy family. He has good intentions, even if he is dishonest about how he achieves success, and just wants to create a better life for his family.

After the run-in with Moon-gwang and her husband, Ki-woo becomes exceedingly attached to the lucky rock that his friend gave him, and carries it around as a totem. After Geun-sae bludgeons him with it, Ki-woo emerges from a coma all the more motivated to ascend the class ladder, buy the Parks' home, and reunite with his father, who is living in the subterranean bunker.
