Leobeu (러브 / Leobeu) (1999)

A marathon runner goes to LA to live with his brother and an adopted sister he never met. He feels an attraction towards her, but she can't seem to stand him and just ignores him at will. While he admires her from afar, a team-mate of his finds him in LA and begs for his return to Korea. His story unfolds before the brother and adopted sister's very eyes. And at that moment, she begins to respect him and the feeling gradually becomes mutual.
