Made in Hong Kong (1997) Fruit Chan

Autumn Moon is a young, gonowhere triad whose selfregard far outstrips his talents or accomplishments. While working as a debt collector, Moon meets feisty teen Ping, who suffers from renal failure and needs a kidney transplant, though her chances of receiving one are slim. Nevertheless, Moon falls for Ping and idealistically resolves to improve himself and become her saviour. But that goal may be futile for someone of Moons station and temperament.
