Oasis (2002) on Netflix

Jong-du, a young man just out of prison for manslaughter, is a social misfit: fidgety, snuffling, laughing inappropriately, without a super ego. When released, he calls on the family of the victim; they send him away, but not before he has seen Gong-ju, a young woman disabled severely by cerebral palsy. Both are abused by their families, and both are used by them as well. Although their relationship begins with Jong-du's criminal behavior, a friendship develops. They talk of favorite things; he washes her hair; they go out; in late night phone calls, he helps her past her fears of the dark. Is there a place in the world for these two inarticulate people?
