サンケンロック

Ken Kitano, a Japanese delinquent, drops out and follows Yumin, the girl he loves, to South Korea after she leaves to become a police officer there. Broke and adrift in Seoul, he saves an old man from a beating and is recruited by a small street gang, which makes him its boss. As the Sun-Ken Rock group grows, Ken hides his criminal life from Yumin, who despises gangs and has no idea what he does.
