The Kim family—father Ki-taek, mother Chung-sook, daughter Ki-jung and son Ki-woo—live in a small semi-basement apartment (banjiha),[10] have low-paying temporary jobs as pizza box folders, and struggle to make ends meet.[11] One day, Min-hyuk, a friend of Ki-woo's and a university student, gives the family a scholar's rock, which is meant to promise wealth to whoever possesses it. He suggests that, when he leaves to study abroad, Ki-woo should take over his job as an English tutor to the wealthy Park family's daughter, Da-hye. Ki-woo poses as a university student and is hired by the Parks; Mrs. Park decides they will call him "Kevin".
