Friend 2

Sung-Hoon was raised by his mother and doesn't have any memories of his real father. His childhood was miserable, surrounded by his mother's gangster friends. He eventually became a gang member himself. He is now imprisoned for fighting against other gang members in a Buddhist temple. Meanwhile, Joon-Seok has been in prison for almost 17 years and is set for release in the near future. A woman comes to the prison and requests to talk with Joon-Seok. The woman was in his circle of friends during his high school days. She informs Joon-Seok that her son Sung-Hoon is an inmate in the same prison. She asks Joon-Seok to protect her son from other gang members. Joon-Seok soon takes Sung-Hoon under his wings in prison.
