Friend (Hangul: 친구; RR: Chin-gu) is a 2001 South Korean film written and directed by Kwak Kyung-taek. Upon its release, it became the highest-grossing South Korean movie of all time. Its record was surpassed in 2003 by Silmido.
This film is the director's experience about his friends, a semi-autobiography set in his hometown, Busan, and the actors speak with a strongly accented Busan dialect. The film changed the public images of Jang Dong-gun and Yu Oh-seong; previously, Jang had been famous for romantic comedies and Yu had appeared in movies with mostly cult interest.
The film follows the lives of four childhood friends: Joon-seok, the leader of the group and whose father is a powerful mob boss; Dong-su, whose father is an undertaker; class clown Jung-ho; and Sang-taek, who was an exemplary student. As children they play together, sell sexually explicit pictures cut from a magazine, and wonder if a South Korean Olympic swimmer could outrace a sea turtle. Jung-ho also showed the rest of them a VCR that his mother had, and this film he found on it. It turns out to be a pornographic movie, and the boys are entranced while arguing over what a "menstruation" was, with them believing that it was the word that adults used to describe the "vagina".
as i walked inside i donned a smile that wasn't mine, i need to leave it behind. my eyes were stained red, cuz i was crying again, now i just need a friend. [chorus] i had it all, but i still wanted more, and now i'm stuck with almost nothing at all, i don't know why you put up with all the stupid shit that, i tired to pull of on you, you're still by my side. and i can see your crying face, but i just can't erase it sets it all back into place. i read the note you wrote 1000 times again, now i just need a friend...... [chorus] you're still by my side.
