His family moved to Tokyo and stayed in hiding for a while until the people found his family. His father was murdered by these people and after this Choi was forced to work for them or watch them kill his mother to. This turned Choi in to the life of crime. During this time he moved around a lot in Europe doing work for them until one day his mother told him to escape and leave. So after this Choi moved away to America. He stayed in Washington DC for almost 10 years before moving to Los Santos.

But the tickets started to pile up due to him driving recklessly and he had to find a job. He meet Jeffrey Connors and Winter Springs one day and asked if they have any work.
