돌아온 사나이(1960) / A Returned Man (Dol-a-on sana-i) (1960)

A man drafted into the Pacific War comes home with a burned face and, believing his wife has buried him, quietly raises another lost child instead of finding her, while she remarries and brings up the son he never knew he had. Years later their paths cross at a company party, and the film spends its last stretch on whether a man can undo a life he built out of shame.
