Friend
친구 (original)
Despite their different family backgrounds, four friends grew up together in the wearisome years of the 70s. But as time goes by, each of them takes a different life path. After enrolling in college, Sang-taek and Joong-ho return to visit Dong-su and Joon-suk, only to find one of them in jail and the other on drugs. Slowly life takes difficult turns where friends become rivals in the crime world. Regarded as the quintessential crime saga of Korean cinema, Friend was the highest grossing South Korean movie of all time upon its release.
