Hundreds of enthusiastic fans were packed in a small space to welcome the actor/model. The movie is a sequel of the 2001 South Korean box office hit "Friend," which was highest grossing South Korean film of all time until 2003.
Kim plays the role of Sung Hoon, a gangster who was put in prison and hooks up with his fellow inmate Joon Seok, played by South Korean actor Yu Oh Seong.
The two soon scheme to help Joon regain power in his gang.
Kim admitted that the pressure of sharing leads with acclaimed South Korean actors Yu Oh Seong and Joo Jin Mo was great, but advice from the two helped him to act better.
"They are such established actors, so there is definitely some pressure. I'd be lying if I said there was no pressure. The thing I worried most about was that they were acclaimed actors. I don't want to sully their name, so I tried my best to act out my part. I want to give my thanks to the two actors, who taught me a lot. I told them that I love them," he explained.
